The 20 amino acids that comprise proteins;
18 of them are
Nonpolar Amino Acids: “GAVIL” (Glycine, Alanine, Valine, Isoleucine, Leucine)
Polar Amino Acids: “STAG” (Serine, Threonine, Asparagine, Glutamine)
Acidic Amino Acids: “DE” (Aspartate, Glutamate)
Basic Amino Acids: “LARH” (Lysine, Arginine, Histidine)
Aromatic Amino Acids: “PheTyrTrp” (Phenylalanine, Tyrosine, Tryptophan)
Heterocyclic Amino Acid: “Pro” (Proline)
Remember that essential amino acids are those our bodies cannot produce, so we need to obtain them through our diet. Aspartic acid, being non-essential, doesn’t fall into that category, but it’s still valuable for overall health.
a fascinating amino acid with several important roles in the body:
Structure and Function:
Cysteine is a non-essential amino acid, meaning our bodies can synthesize it.
It’s a key component of glutathione, a powerful antioxidant found in all tissues.
Glutathione is made from cysteine, glutamic acid, and glycine.
Cysteine is also a building block for collagen, which affects skin elasticity and texture.
It’s a major protein in skin, nails, and hair (found in beta-keratin).
Antioxidant Properties:
Cysteine’s thiol side chain participates in enzymatic reactions as a nucleophile.
It contributes to the antioxidant activity of glutathione, protecting cells from oxidative damage.
Health Benefits:
Supports detoxification processes.
Aids in hair and nail tissue recovery.
Helps protect the brain and liver from alcohol, drugs, and cigarette smoke damage.
Guards against harmful toxins and radiation effects.
May reduce the effects of aging, promote muscle building, and aid fat burning.
Encourages white blood cell activity and supports immune function.
Food Sources:
Cysteine can be produced by our bodies, but it’s also found in high-protein foods like pork, chicken, eggs, milk, and cottage cheese.
Vegetarians can get it from garlic, granola, and onions.
Essentiality: Glutamic acid is a non-essential amino acid.
Function:
Abundant in the brain, playing a role in neural communication.
Converts to glutamine and vice versa during metabolic processes.
Food Sources: Found in plant proteins, beef, poultry, dairy, eggs, seafood, and soy.
AGEs play a significant role in aging and age-related cognitive decline by contributing to oxidative stress, inflammation, and various forms of cellular damage in the brain. Adopting a lifestyle and diet that minimize AGE formation can help protect brain health and reduce the risk of neurodegenerative diseases.
AGEs are harmful compounds formed when proteins or fats combine with sugars in the bloodstream through a process called glycation. They accumulate naturally as we age and are also found in certain foods, particularly those that are processed or cooked at high temperatures.
Oxidative Stress:
AGEs increase oxidative stress in the brain by generating free radicals. This oxidative damage can impair cellular functions and contribute to neurodegeneration.
Inflammation:
AGEs can bind to specific receptors called RAGE (Receptor for Advanced Glycation End-products), triggering inflammatory pathways. Chronic inflammation is linked to various neurological conditions.
Impaired Blood-Brain Barrier (BBB):
The accumulation of AGEs can weaken the blood-brain barrier, making it more permeable to harmful substances, which can lead to neuronal damage and contribute to cognitive decline.
Protein Cross-linking:
AGEs can cause proteins to cross-link and form aggregates, disrupting normal cellular functions. This is similar to the formation of amyloid plaques in Alzheimer's disease.
Mitochondrial Dysfunction:
AGEs impair mitochondrial function, reducing energy production and increasing the production of reactive oxygen species, which can further damage brain cells.
Hippocampus:
The hippocampus is crucial for memory and learning. AGE accumulation in this region is associated with cognitive decline and memory impairment.
Cortex:
The cortex, involved in higher-order brain functions such as thought, perception, and memory, can also be affected by AGE-related damage, leading to reduced cognitive abilities.
Amygdala:
Involved in emotional regulation, the amygdala can be impacted by AGEs, potentially affecting mood and increasing the risk of anxiety and depression.
Basal Ganglia:
This region, important for motor control and various cognitive functions, can be adversely affected, potentially contributing to movement disorders like Parkinson's disease.
Dietary Modifications:
Reduce High-AGE Foods: Limit consumption of foods cooked at high temperatures (e.g., fried, grilled, roasted).
Increase Antioxidant-rich Foods: Fruits, vegetables, and whole grains can help neutralize free radicals and reduce oxidative stress.
Healthy Cooking Methods:
Prefer steaming, boiling, or slow-cooking over high-temperature methods to reduce AGE formation in foods.
Glycemic Control:
Maintain stable blood sugar levels through a balanced diet, regular exercise, and possibly medication if necessary.
Lifestyle Factors:
Regular Exercise: Physical activity can help reduce oxidative stress and improve overall health.
Smoking Cessation: Smoking increases AGE formation, so quitting can significantly lower AGE levels.
Supplements and Medications:
Certain compounds, such as vitamins C and E, and medications like metformin, have been shown to reduce AGE levels and their effects.
Exercise is an especially effective tool for helping to offset decreases in metabolism related to weight loss. To keep your metabolism revved, the American College of Sports Medicine says:
aim for more than 250 minutes of moderate aerobic activity each week plus
two strength training sessions.
(Note: The strength sessions should be at least 48 hours apart to give your muscles time to recover.)
Aerobic activity, also known as cardio exercise, is highly effective for weight loss and long-term weight maintenance. Here are some key points about how aerobic activity contributes to weight management:
Calorie Burning: Aerobic exercises increase your heart rate and help burn calories. The more intense the activity, the more calories you burn, which aids in creating a calorie deficit necessary for weight loss.
Fat Loss: Consistent aerobic activity helps reduce body fat, particularly visceral fat, which is associated with numerous health risks.
Metabolic Boost: Regular aerobic exercise boosts your metabolism, helping you burn more calories even at rest.
Walking: A simple and accessible form of aerobic exercise. Brisk walking can significantly contribute to weight loss and maintenance.
Running/Jogging: High-calorie burning activities that improve cardiovascular health and stamina.
Cycling: Both outdoor cycling and stationary biking are excellent for burning calories and improving leg strength.
Swimming: A full-body workout that is gentle on the joints while providing significant calorie burn.
Dancing: Engaging and fun, dancing can be a great way to burn calories and improve overall fitness.
Group Fitness Classes: Classes such as Zumba, step aerobics, or kickboxing provide a structured and social way to engage in aerobic exercise.
Frequency: Aim for at least 150 minutes of moderate-intensity or 75 minutes of high-intensity aerobic activity per week, as recommended by the CDC. For substantial weight loss, more exercise may be needed.
Intensity: Mix moderate and high-intensity workouts to maximize calorie burn and improve cardiovascular health. High-Intensity Interval Training (HIIT) is particularly effective.
Consistency: Regular exercise is crucial for maintaining weight loss. Incorporate aerobic activities into your daily routine to ensure consistency.
Variety: Mix different types of aerobic exercises to keep your workouts interesting and target different muscle groups.
Tracking: Monitor your progress through fitness apps, wearables, or a simple exercise log to stay motivated and track your improvements.
Set Realistic Goals: Start with achievable goals and gradually increase the intensity and duration of your workouts.
Stay Hydrated: Drink plenty of water before, during, and after exercise to stay hydrated.
Warm-Up and Cool-Down: Always begin with a warm-up and end with a cool-down to prevent injury and aid in recovery.
Listen to Your Body: Pay attention to your body’s signals and avoid overtraining. Rest is crucial for recovery and long-term success.
Combine with Strength Training: Incorporate strength training exercises to build muscle, which can help increase your resting metabolic rate.
By integrating regular aerobic activity into your lifestyle, you can effectively lose weight and keep it off, improving your overall health and well-being.

Akkermansia muciniphila is a fascinating gut bacterium that resides in the mucus layer of the colon. Here are some key points about it:
Role: It plays a pivotal role in maintaining gut health and preventing chronic diseases. Specifically, it helps protect the intestinal epithelial cells, which act as a barrier between your immune system and the gut environment2.
Natural Boost: You can increase your levels of Akkermansia naturally by focusing on real food. A healthy diet rich in fiber, polyphenols, and prebiotics can support its growth2.
Peptide-tyrosine-tyrosine (PYY) released by the intestine
Peptide YY (PYY), also known as peptide tyrosine-tyrosine, is a gut hormone synthesized and secreted by enteroendocrine cells mainly in the distal small intestine (jejunum and ileum) and large intestine in response to feeding1. Here are some key points about PYY:
Function: PYY acts as a satiety signal, helping to reduce food intake. When released, it contributes to feelings of fullness and satisfaction after a meal.
Structure: PYY is a short peptide consisting of 36 amino acids. The two major forms are PYY 1-36 and PYY 3-36. PYY 3-36 is the most common form in circulation and binds to the Y2 receptor, influencing appetite regulation2.
Release Mechanism: Luminal free fatty acids (FFAs) can trigger the release of PYY from endocrine cells in the lower intestine. Its biological actions include inhibiting gut motility and gastrointestinal and pancreatic secretions3.
Orexigenic and anorexigenic pathways.
These neurons stimulate eating and encourage appetite.
Key neuropeptide hormones associated with orexigenic activity include:
Anorexigenic Neurons:
These neurons suppress appetite, helping to regulate food intake.
Notable anorexigenic hormones include:
Understanding these pathways is crucial for maintaining a balanced energy homeostasis.
A hormone disruptor.
Bisphenol A (BPA) is indeed an endocrine disruptor. It has been incorporated into many plastics used in everyday items, such as plastic bottles, food containers, and cash register receipts. BPA’s structure resembles natural estrogen, allowing it to bind to estrogen receptors in cells and induce inappropriate responses, including increased cell proliferation that could promote tumor development
Endocrine disruptors are natural or synthetic chemicals that can interfere with the hormone system in various ways. These disruptions may include increasing the production of some hormones, decreasing the production of others, and interfering with their signaling, which can lead to health problems123. Here are some common endocrine disruptors:
Bisphenol A (BPA): Used in polycarbonate plastics and epoxy resins, BPA is found in food packaging, toys, and other applications.
Atrazine: A widely applied herbicide used to control weeds in crops like corn, sorghum, and sugarcane.
Dioxins: Byproducts of certain manufacturing processes, such as herbicide production and paper bleaching.
Perchlorate: An industrial chemical used in rockets, explosives, and fireworks, sometimes found in groundwater.
Phthalates: Used as liquid plasticizers in products like food packaging, cosmetics, fragrances, and children’s toys.
Phytoestrogens: Naturally occurring substances with hormone-like activity found in some plants, such as soy foods.
Remember that while complete avoidance of endocrine disruptors is challenging, making informed choices can help reduce exposure and potential health effects.
It is caused by consuming proteins with sugars or fats.

is the rate at which your body burns energy for basic functions, such as breathing or making your heart beat, as well as building cells, hormones, and antibodies.
Cellular signaling and fats are intricately connected as lipids play crucial roles in the processes of cellular communication. Here are some key points to understand how fats, particularly lipids, are involved in cellular signaling:
Phospholipids: Major components of cell membranes, creating a bilayer that serves as a barrier and platform for signaling molecules.
Steroids: Cholesterol and other steroids are involved in membrane structure and function, and can also serve as signaling molecules themselves (e.g., steroid hormones).
Sphingolipids: Involved in cell membrane structure and signaling pathways.
Eicosanoids: Derived from arachidonic acid, these include prostaglandins, thromboxanes, and leukotrienes, which are involved in inflammatory responses and other signaling processes.
Lipid Bilayer: The cell membrane's lipid bilayer is essential for creating a controlled environment for cellular signaling. It houses receptors, ion channels, and other proteins crucial for signal transduction.
Microdomains (Lipid Rafts): Specific areas within the lipid bilayer, known as lipid rafts, are enriched in cholesterol and sphingolipids. These rafts organize signaling molecules for efficient signal transduction.
G-Protein Coupled Receptors (GPCRs): These receptors traverse the lipid bilayer and are involved in transmitting signals from extracellular ligands (e.g., hormones, neurotransmitters) to intracellular G-proteins, initiating various signaling cascades.
Tyrosine Kinase Receptors: These receptors also span the membrane and, upon binding to their ligands, activate intracellular signaling pathways through phosphorylation events.
Diacylglycerol (DAG) and Inositol Triphosphate (IP3): These molecules are generated from the phospholipid PIP2 by the action of phospholipase C. DAG remains in the membrane and activates protein kinase C (PKC), while IP3 diffuses through the cytoplasm to release calcium from intracellular stores.
Arachidonic Acid: Released from membrane phospholipids, it serves as a precursor for eicosanoids, which are potent signaling molecules involved in inflammation and other cellular processes.
Prostaglandins: These are involved in the regulation of inflammation, blood flow, and the formation of blood clots.
Sphingosine-1-phosphate (S1P): Plays roles in immune cell trafficking, angiogenesis, and cell survival.
Ceramide: Involved in apoptosis (programmed cell death) and stress responses.
Membrane Fluidity: The types of fats present in the cell membrane affect its fluidity and, consequently, the function of membrane proteins and signaling pathways.
Lipid Composition: Changes in lipid composition can modulate signaling pathways. For instance, diets high in certain fats can alter membrane composition and affect signaling related to insulin resistance and inflammation.
Cholesterol: Necessary for the formation of lipid rafts and proper functioning of membrane proteins. Both too much and too little cholesterol can disrupt cellular signaling.
Dietary Fats: Omega-3 and omega-6 fatty acids from the diet can be converted into signaling molecules (e.g., eicosanoids) that have different effects on inflammation and cellular responses.
Fats are integral to cellular signaling, affecting the structure and function of cell membranes, acting as second messengers, and serving as precursors for various signaling molecules. The balance and types of fats in the diet and within the body play crucial roles in maintaining healthy cellular communication and overall physiological functions.
bond dipoles
intermolecular forces
molecular geometry
Bond dipoles are a measure of the polarity of a chemical bond between two atoms. They arise when there is a difference in electronegativity between the bonded atoms, causing a partial positive charge to develop on the less electronegative atom and a partial negative charge on the more electronegative atom. This creates a dipole moment, which is a vector quantity with both magnitude and direction.
Dipole Moment (μ): The dipole moment is calculated as the product of the charge difference and the distance between the charges. It is usually expressed in Debye units (D).
Electronegativity: The ability of an atom to attract electrons towards itself in a chemical bond. When two atoms have different electronegativities, a bond dipole is formed.
Intermolecular forces are forces of attraction or repulsion between molecules (as opposed to intramolecular forces, which hold atoms together within a molecule). These forces are responsible for many physical properties of substances, such as boiling points, melting points, and solubilities.
London Dispersion Forces (Van der Waals Forces): Weakest intermolecular forces caused by the temporary polarization of molecules due to the movement of electrons.
Dipole-Dipole Interactions: Forces between polar molecules where positive and negative dipoles interact.
Hydrogen Bonds: A special type of dipole-dipole interaction, which occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine. Hydrogen bonds are stronger than regular dipole-dipole interactions.
Ion-Dipole Interactions: Forces between an ion and a polar molecule. These are particularly important in solutions of ionic compounds in polar solvents like water.
Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule. The geometry of a molecule affects its physical and chemical properties, including reactivity, polarity, phase of matter, color, magnetism, and biological activity.
VSEPR Theory (Valence Shell Electron Pair Repulsion Theory): A model used to predict the geometry of molecules based on the repulsion between electron pairs around a central atom. The idea is that electron pairs (bonding and lone pairs) will arrange themselves as far apart as possible to minimize repulsion.
Common Geometries:
Linear: Bond angle of 180°, as seen in CO2.
Trigonal Planar: Bond angle of 120°, as seen in BF3.
Tetrahedral: Bond angle of 109.5°, as seen in CH4.
Trigonal Bipyramidal: Bond angles of 90° and 120°, as seen in PCl5.
Octahedral: Bond angle of 90°, as seen in SF6.
Bent/Angular: Seen in molecules with lone pairs on the central atom, like H2O.
Trigonal Pyramidal: Seen in NH3.
Understanding these concepts is crucial in predicting and explaining the behavior of molecules in various chemical contexts.
Beef, chicken liver, salmon, and eggs are the major source of choline.
Cortisol stimulates appetite through a combination of physiological and psychological mechanisms, including the mobilization of energy stores, influence on metabolic processes, effects on appetite-regulating hormones, and impact on brain regions responsible for hunger and reward. This complex interplay ensures that the body has sufficient energy to manage stress but can also lead to increased food intake and potential weight gain if stress and cortisol levels remain chronically elevated.
Cortisol is produced by the adrenal glands in response to stress. It plays various roles in the body, including regulating metabolism, immune response, and the stress response. Here’s why cortisol stimulates appetite:
(DHA) is an essential omega-3 fatty acid found in cold-water fish, such as salmon. It plays a crucial role in the development of eye and nerve tissues1. Your body needs DHA for a healthy brain, and it’s also beneficial for heart health
dietary requirements can vary based on genetics, health status, and lifestyle.
Animal-Based Foods Only:
The diet consists entirely of animal products, including beef, pork, chicken, fish, eggs, and some dairy (especially those low in lactose like butter, hard cheeses, and heavy cream).
Exclusion of Plant Foods:
All plant-based foods are excluded, including fruits, vegetables, grains, legumes, nuts, and seeds.
Focus on Fatty Cuts:
Emphasis is often placed on fatty cuts of meat to ensure adequate calorie intake and to maintain ketosis, similar to the ketogenic diet.
Simple Meal Preparation:
Meals are simple, often just a piece of meat cooked with minimal seasoning or preparation.
Weight Loss:
Many people report significant weight loss on the carnivore diet due to the elimination of carbohydrates and potential reduction in overall calorie intake.
Improved Mental Clarity:
Some individuals experience enhanced mental clarity and focus, possibly due to stable blood sugar levels and reduced intake of inflammatory foods.
Reduced Inflammation:
By eliminating plant-based foods that can be inflammatory for some people, the diet may help reduce overall inflammation and related symptoms.
Digestive Health:
People with certain digestive issues, such as irritable bowel syndrome (IBS) or Crohn’s disease, might find relief from symptoms by following a carnivore diet.
Simplification of Food Choices:
The diet simplifies food choices and meal planning, which can be appealing for those who find it challenging to navigate complex dietary guidelines.
Nutrient Deficiencies:
Eliminating all plant foods can lead to deficiencies in essential nutrients such as vitamin C, fiber, and various phytonutrients. It’s crucial to monitor and address potential deficiencies.
Long-Term Sustainability:
The restrictive nature of the diet can make it difficult to sustain long-term, both socially and practically.
Lack of Fiber:
The absence of fiber in the diet can lead to digestive issues for some individuals, such as constipation.
Potential Health Risks:
High consumption of red and processed meats has been associated with increased risks of certain diseases, including cardiovascular disease and some cancers. The long-term health effects of a carnivore diet are not well-studied.
Social and Practical Challenges:
Adhering to a strict carnivore diet can be challenging in social situations and when eating out, as it severely limits food choices.
The carnivore diet is a highly restrictive eating plan that focuses solely on animal products. While some individuals report significant health benefits, it is essential to approach the diet with caution due to potential nutrient deficiencies and other health risks. Consulting with a healthcare provider or a registered dietitian before starting the carnivore diet is advisable, especially for those with underlying health conditions or concerns about nutritional adequacy.
is taken to mean the traditional diets in a much broader region, including southern France and Spain as well as Morocco, Turkey, Syria, Israel, Lebanon, and Egypt..
The classic Mediterranean diet is the eating pattern of the people who lived in areas bordering the Mediterranean Sea—especially the olive-growing areas of Crete, Greece, and southern Italy—in the late 1950s and early 1960s. This is the time period after the region overcame the food shortages and economic difficulties following World War II but before socioeconomic changes introduced more meat, processed foods, and vegetable oils other than olive oil. Today, "Mediterranean diet" is taken to mean the traditional diets in a much broader region, including southern France and Spain as well as Morocco, Turkey, Syria, Israel, Lebanon, and Egypt.
The traditional Mediterranean diet is characterized by:
• High consumption of vegetables, fruits, legumes, and whole or minimally processed grains.
• Low consumption of meat and meat products (maybe two to three times per month).
• Low consumption of dairy products.
The primary fat is olive oil, which is used to cook and dress the abundant vegetables and legumes. Grains are whole or in the form of fermented sourdough breads or pasta cooked al dente, which lowers the glycemic index and the glycemic load (measures of how the carbohydrates in a specific food affect blood sugar levels).
The combination of the various components of the Mediterranean diet may be more important than any one component in isolation. In other words, it’s about more than just the olive oil or the red wine. For example, when you stew vegetables in olive oil with garlic, onion, parsley, oregano, and basil, you are creating a dish rich in fiber, vitamins, minerals, and phytochemicals, as well as healthy monounsaturated fats.
A number of observational studies have found that a
Mediterranean diet is associated with reduced risk of developing
several chronic diseases—including cancer, Parkinson’s disease,
Alzheimer’s disease, type 2 diabetes, and cardiovascular disease.
Some clinical trials echo those findings.
The PREDIMED study enrolled 7,447 adults at high risk for
cardiovascular disease and followed them for eight years. The
participants were randomly assigned to follow one of three diets—a
Mediterranean diet supplemented with olive oil, a Mediterranean
diet supplemented with nuts, or a lower-fat diet (the control
group). The results show Mediterranean diet benefits to include a
significant reduction in heart attacks, strokes, and cardiovascular
deaths, as well as reduced risks of developing type 2 diabetes,
peripheral artery disease, and breast cancer.
Was developed by Martha Clare Morris, a nutritional epidemiologist at Rush University Medical Center, through a study funded by the National Institute on Aging.
There are also five food groups to limit in the MIND diet:
• Red meat: less than four meals per week.
• Butter and stick margarine: less than one serving per week.
• Cheese: less than one serving per week.
• Pastries and sweets: less than five servings per week.
• Fast food: less than once per week.

• naltrexone-bupropion (Contrave)
• liraglutide (Saxenda)
• phentermine-topiramate (Qsymia).
Physicians typically prescribe weight-loss medications to people with obesity or those who are overweight with weight-related health risks. If you have a body mass index (BMI) of 30 or more or a BMI of 27 or more with weight-related health risks such as heart disease or type 2 diabetes, and if you haven’t been able to lose weight through lifestyle changes alone, you’re a candidate.
When people are given larger portions of food, they tend to eat more, leading to increased caloric intake. This portion size effect can contribute to weight gain and has significant implications for public health and obesity prevention. Strategies to address this include promoting smaller portion sizes, educating people about portion control, and encouraging mindful eating practices.
Endocrine disruptors are natural or synthetic chemicals that can interfere with the hormone system in various ways. These disruptions may include increasing the production of some hormones, decreasing the production of others, and interfering with their signaling, which can lead to health problems123.
Common endocrine disruptors:
Remember that while complete avoidance of endocrine disruptors is challenging, making informed choices can help reduce exposure and potential health effects.
Endorphins are a group of hormones produced by the central nervous system and the pituitary gland. They function as neurotransmitters and play a crucial role in the body's ability to manage pain and stress. The name "endorphin" is derived from "endogenous," meaning produced within the body, and "morphine," a pain-relieving substance. Here are key points about endorphins:
Pain Relief:
Natural Painkillers: Endorphins act on the opiate receptors in the brain, reducing the perception of pain and promoting a feeling of well-being.
Response to Injury: They are released in response to pain and stress, helping to alleviate discomfort.
Stress Reduction:
Stress Response: Endorphins are released during periods of stress to help the body manage and mitigate stress effects.
Calming Effect: They induce a sense of calm and relaxation, which can help reduce anxiety and tension.
Mood Enhancement:
Euphoria: High levels of endorphins can lead to feelings of euphoria, often referred to as the "runner's high" experienced after prolonged exercise.
Antidepressant Effect: Endorphins can improve mood and have a mild antidepressant effect.
Immune System Boost:
Immune Function: Some studies suggest that endorphins can enhance immune system function, contributing to overall health.
Exercise:
Physical Activity: Activities like running, swimming, cycling, and even walking can stimulate the release of endorphins.
Intensity: Higher intensity exercises tend to produce a greater release of endorphins.
Food:
Spicy Foods: Consumption of spicy foods containing capsaicin can trigger endorphin release.
Chocolate: Eating chocolate can also stimulate the production of endorphins.
Laughter:
Humor: Laughing, especially deep belly laughs, can increase endorphin levels.
Acupuncture and Massage:
Alternative Therapies: Acupuncture and massage therapy have been shown to promote the release of endorphins, providing pain relief and relaxation.
Social Interactions:
Positive Social Interactions: Engaging in social activities and forming strong social bonds can boost endorphin levels.

Mind-Body Practices: Practices like meditation, yoga, and deep breathing exercises can enhance the release of endorphins.
Here is a comprehensive list of the essential nutrients, vitamins, and minerals that both males and females need for optimal health. The specific daily requirements may vary based on age, sex, and life stage.
Exercise is an especially effective tool for helping to offset decreases in metabolism related to weight loss. To keep your metabolism revved, the American College of Sports Medicine says to aim for more than 250 minutes of moderate aerobic activity each week plus two strength training sessions. (Note: The strength sessions should be at least 48 hours apart to give your muscles time to recover.)
New research indicates that physical activity helps regulate weight in ways that go well beyond energy expenditure. A combination of aerobic exercise and strength training boosts levels of a hormone-like substance called irisin, which is generated in skeletal muscles and travels through the bloodstream to fat tissue and other organs.
Irisin nudges the composition of fat tissue in a healthier direction by turning some of your white fat cells (which are mainly storage depots for calories) into beige cells (which resemble energy-burning, heat-producing brown cells).
Irisin levels naturally decline with age, so exercise is an important way of keeping up levels in older adults. High levels of irisin are associated with greater muscle mass and strength, as well as greater insulin sensitivity—an important factor for anyone with diabetes. By contrast, low levels correlate with obesity and insulin resistance.
Exercise also enhances your gut bacteria
Exercising increases the levels of the bacterium Akkermansia muciniphila, which is believed to be associated with lower levels of obesity and related metabolic disorders.
Akkermansia muciniphila is a type of bacteria that resides in the human gut. It has garnered significant interest in recent years due to its potential health benefits and role in maintaining gut health. Here are some key points about Akkermansia muciniphila:
Gram-Negative Bacterium: It is a Gram-negative, anaerobic bacterium.
Mucin-Degrading: A. muciniphila is known for its ability to degrade mucin, a glycoprotein component of the mucus layer lining the gut.
Gut Barrier Integrity: By degrading mucin, A. muciniphila plays a role in maintaining and renewing the mucus layer of the gut, which is crucial for gut barrier integrity.
Metabolic Health: Research has shown that higher levels of A. muciniphila are associated with improved metabolic health, including better glucose metabolism and reduced body weight.
Anti-Inflammatory Effects: A. muciniphila has been linked to anti-inflammatory effects in the gut, which may help in conditions like inflammatory bowel disease (IBD) and other inflammatory conditions.
Immune System Modulation: It can influence the immune system, potentially enhancing immune responses and maintaining immune homeostasis.
Obesity and Diabetes: Studies have suggested that A. muciniphila may help in managing obesity and type 2 diabetes by improving insulin sensitivity and reducing fat mass.
Probiotic Potential: Due to its beneficial effects, there is growing interest in developing A. muciniphila-based probiotics or supplements.
Gut Microbiota Composition: A. muciniphila is considered a beneficial member of the gut microbiota, and its presence is often associated with a healthy gut microbial ecosystem.
Diet and Prebiotics: Certain dietary components, such as prebiotics (e.g., inulin), can promote the growth of A. muciniphila in the gut.
Fiber-Rich Foods: Consuming a diet rich in fiber can help support a healthy gut microbiota, including A. muciniphila.
Akkermansia muciniphila is an important gut bacterium with several potential health benefits, particularly in maintaining gut barrier function, metabolic health, and reducing inflammation. Ongoing research continues to explore its role in human health and its potential therapeutic applications.

exercise just makes you feel better by increasing your blood levels of endorphins—the “feel-good” chemicals often credited for the “runner’s high.”
Fats are integral to cellular signaling, affecting the structure and function of cell membranes, acting as second messengers, and serving as precursors for various signaling molecules. The balance and types of fats in the diet and within the body play crucial roles in maintaining healthy cellular communication and overall physiological functions.
Polyunsaturated Omega Fatty Acids
You will find beneficial monounsaturated and polyunsaturated fats in olive, canola, sunflower, and safflower plant and oils as well as in avocados, nuts, seeds, olives, and fatty fish such as salmon and sardines.
Cellular signaling and fats are intricately connected as lipids play crucial roles in the processes of cellular communication. Here are some key points to understand how fats, particularly lipids, are involved in cellular signaling:
Phospholipids: Major components of cell membranes, creating a bilayer that serves as a barrier and platform for signaling molecules.
Steroids: Cholesterol and other steroids are involved in membrane structure and function, and can also serve as signaling molecules themselves (e.g., steroid hormones).
Sphingolipids: Involved in cell membrane structure and signaling pathways.
Eicosanoids: Derived from arachidonic acid, these include prostaglandins, thromboxanes, and leukotrienes, which are involved in inflammatory responses and other signaling processes.
Lipid Bilayer: The cell membrane's lipid bilayer is essential for creating a controlled environment for cellular signaling. It houses receptors, ion channels, and other proteins crucial for signal transduction.
Microdomains (Lipid Rafts): Specific areas within the lipid bilayer, known as lipid rafts, are enriched in cholesterol and sphingolipids. These rafts organize signaling molecules for efficient signal transduction.
G-Protein Coupled Receptors (GPCRs): These receptors traverse the lipid bilayer and are involved in transmitting signals from extracellular ligands (e.g., hormones, neurotransmitters) to intracellular G-proteins, initiating various signaling cascades.
Tyrosine Kinase Receptors: These receptors also span the membrane and, upon binding to their ligands, activate intracellular signaling pathways through phosphorylation events.
Diacylglycerol (DAG) and Inositol Triphosphate (IP3): These molecules are generated from the phospholipid PIP2 by the action of phospholipase C. DAG remains in the membrane and activates protein kinase C (PKC), while IP3 diffuses through the cytoplasm to release calcium from intracellular stores.
Arachidonic Acid: Released from membrane phospholipids, it serves as a precursor for eicosanoids, which are potent signaling molecules involved in inflammation and other cellular processes.
Prostaglandins: These are involved in the regulation of inflammation, blood flow, and the formation of blood clots.
Sphingosine-1-phosphate (S1P): Plays roles in immune cell trafficking, angiogenesis, and cell survival.
Ceramide: Involved in apoptosis (programmed cell death) and stress responses.
Membrane Fluidity: The types of fats present in the cell membrane affect its fluidity and, consequently, the function of membrane proteins and signaling pathways.
Lipid Composition: Changes in lipid composition can modulate signaling pathways. For instance, diets high in certain fats can alter membrane composition and affect signaling related to insulin resistance and inflammation.
Cholesterol: Necessary for the formation of lipid rafts and proper functioning of membrane proteins. Both too much and too little cholesterol can disrupt cellular signaling.
Dietary Fats: Omega-3 and omega-6 fatty acids from the diet can be converted into signaling molecules (e.g., eicosanoids) that have different effects on inflammation and cellular responses.
Fats are integral to cellular signaling, affecting the structure and function of cell membranes, acting as second messengers, and serving as precursors for various signaling molecules. The balance and types of fats in the diet and within the body play crucial roles in maintaining healthy cellular communication and overall physiological functions.

They are gases in Earth's atmosphere that trap heat. They let sunlight in but prevent some of the heat that the sunlight brings from leaving the atmosphere. This phenomenon is known as the greenhouse effect, which helps keep our planet warm enough to support life. However, human activities have significantly increased the concentrations of these gases, contributing to global warming and climate change. Here’s an overview of key greenhouse gases, their sources, and their impact:
The greenhouse effect is a natural process where greenhouse gases absorb and emit infrared radiation, warming the Earth’s surface and lower atmosphere. Without this effect, Earth would be too cold to sustain life as we know it. However, the enhancement of the greenhouse effect due to increased concentrations of GHGs is leading to global warming and climate change.
Greenhouse gases are critical components of the Earth’s atmosphere that help regulate its temperature. However, human activities have increased the concentrations of these gases, leading to enhanced greenhouse effects and global warming. Addressing the challenges posed by greenhouse gases requires concerted efforts to reduce emissions, transition to sustainable energy sources, and adopt practices that mitigate their impact on the climate.
Cardiometabolic risk factors are conditions and behaviors that increase the likelihood of developing cardiovascular disease (CVD) and metabolic disorders, such as type 2 diabetes and metabolic syndrome. These risk factors can often be interrelated and tend to cluster together, significantly elevating the overall risk of heart disease, stroke, and diabetes.

Managing these risk factors through healthy lifestyle choices, regular screenings, and appropriate medical interventions can significantly reduce the risk of developing serious health complications.
Iron is a major component of hemoglobin, a protein found in red blood cells. Hemoglobin binds to oxygen in the lungs and carries it to all parts of the body. Without enough iron, there aren’t sufficient red blood cells to transport oxygen, leading to fatigue and weakness12.
Hemosiderin is a protein compound that helps the body store iron. When there’s an excess of hemosiderin in the body, iron becomes trapped within tissues, leading to staining or discoloration of the skin. These golden-yellow-brown spots often appear on the lower legs, particularly between the ankles and knees. The primary cause of hemosiderin staining is chronic venous insufficiency (CVI), which results from compromised blood flow due to ineffective leg vein valves. Other factors, such as trauma, broken bones, or surgical incisions, can also contribute to hemosiderin staining12. While the staining itself is usually painless, it’s essential to address any underlying health conditions associated with it! 😊

are proteins that bind with histamine, a neurotransmitter involved in various physiological processes. There are four main types:
H1 Receptor: These receptors are primarily located on smooth muscle cells, endothelial cells, and neurons. Activation of H1 receptors mediates various responses, including smooth muscle contraction (leading to bronchoconstriction and intestinal cramping), increased vascular permeability (resulting in edema), and stimulation of sensory nerve endings (causing itching and pain). H1 antagonists, commonly known as antihistamines, are used to alleviate symptoms of allergies and allergic reactions1.
H2 Receptor: Found mainly in the stomach lining (parietal cells), H2 receptors regulate gastric acid secretion by stimulating the production of hydrochloric acid. H2 antagonists (H2 blockers) are used to reduce stomach acid production and treat conditions like gastroesophageal reflux disease (GERD) and peptic ulcers1.
H3 Receptor: These receptors are predominantly located in the central nervous system (CNS), particularly in regions associated with neurotransmitter release and modulation. H3 receptors act as presynaptic autoreceptors and heteroreceptors, regulating the release of neurotransmitters such as dopamine, serotonin, norepinephrine, and acetylcholine. Modulation of H3 receptors is being explored as a potential target for various neurological and psychiatric disorders1.
H4 Receptor: Initially discovered on immune cells (mast cells, eosinophils, and T cells), H4 receptors are involved in immune responses, including chemotaxis (cellular movement in response to chemical signals) and cytokine production. These receptors play a role in inflammation and allergic reactions. Ongoing research aims to better understand their involvement in immune-related disorders and develop potential therapeutic interventions1.
Octanoylation refers to the process of modifying a molecule by attaching an eight-carbon fatty acid called octanoate. In the context of the hormone ghrelin, octanoylation occurs at a specific site (Serine 3) and is essential for its biological effects. Ghrelin, which plays a role in energy and glucose homeostasis, requires this modification to bind and activate its receptor. The enzyme responsible for ghrelin octanoylation is ghrelin O-acyltransferase (GOAT)
An octanoylated peptide refers to a peptide that has undergone a specific posttranslational modification called serine octanoylation. In this process, an eight-carbon fatty acid (octanoate) is attached to a serine residue within the peptide. One well-known example of an octanoylated peptide is ghrelin, a hormone involved in energy homeostasis and appetite regulation1. Ghrelin’s octanoylation is essential for its binding to and activation of its receptor, making it a crucial modification for its biological function. Somatotrophs, also known as somatotropic cells, are specialized cells found in the anterior pituitary gland. Here’s what you need to know:
Function: Somatotrophs produce and release growth hormone (GH), also called somatotropin. GH plays a crucial role in stimulating body growth, particularly the growth of epiphyseal cartilages.
Stimulation: These cells are stimulated to release GH in response to somatocrinin (also known as growth hormone-releasing hormone, GHRH), which comes from the hypothalamus.
Percentage: Somatotrophs constitute about 30-40% of the cells in the anterior pituitary.
Clinical Significance:
Deficiency: Low levels of somatotropin can lead to pituitary dwarfism before puberty or during bone tissue growth.
Excess: Over-secretion of growth hormone can cause gigantism (excessive growth) before puberty or acromegaly (abnormal growth in adults).
Remember, these cells play a vital role in regulating growth and overall health.
Push you to eat more
Slows metabolism
Increases when you need to eat.
Ghrelin, also known as the “hunger hormone,” plays a crucial role in regulating appetite and energy balance. Here are some key points about ghrelin:
Production and Release:
Functions:
Appetite Regulation: Ghrelin signals the hypothalamus (a part of the brain) to increase appetite, making you feel hungry when your stomach is empty.
Fat Storage: It promotes fat storage in the body.
Growth Hormone Release: Ghrelin stimulates the pituitary gland to release growth hormones.
Digestive System: It stimulates the movement of food through the digestive system, from the stomach to the intestines.
Insulin Control: Ghrelin also contributes to controlling insulin release.
Cardiovascular Health: It plays a role in protecting cardiovascular health1.
Comparison with Leptin:
Leptin, produced by fat cells, decreases appetite and signals fullness.
Ghrelin and leptin work together to regulate short-term and long-term weight control, respectively1.
Remember that ghrelin levels are highest right before mealtimes, and they decrease after eating
Tells the brain when enough food is on board.
Low level, Lack of energy, food, Leptin makes a signal to eat.
WHEN YOU EAT IN A HURRY: As you eat and drink, your stomach fills, activating stretch receptors in your stomach. These receptors send satiety messages to your brain via the vagus nerve, which connects the brain to the stomach. Then, as food enters your small intestine, appetite hormones are released, sending additional fullness messages to your brain.
The process doesn’t happen immediately. It can take 20 minutes or longer for your brain to realize it’s time to put down your fork. Eating too quickly doesn’t allow this intricate system sufficient time to work, making it easy to overeat without even realizing it.
Eating processed carbohydrates raises insulin levels, and
insulin drives calories into fat cells for storage,
A condition in which the body's cells become less responsive to the hormone insulin. Insulin is crucial for regulating blood sugar levels by facilitating the uptake of glucose (sugar) from the bloodstream into cells for energy. When cells become resistant to insulin, more insulin is needed to achieve the same effect, leading to higher levels of insulin in the blood (hyperinsulinemia) and often higher blood glucose levels.
In insulin resistance, the cells do not respond effectively to insulin. This impairs glucose uptake, leading to elevated blood glucose levels. The pancreas compensates by producing more insulin, but over time, this can lead to pancreatic beta-cell dysfunction and decreased insulin production.
Insulin resistance is a condition where the body's cells become less responsive to insulin, leading to higher blood sugar and insulin levels. It is a significant risk factor for type 2 diabetes and other metabolic disorders. Managing insulin resistance involves lifestyle changes such as improving diet, increasing physical activity, losing weight, and sometimes taking medication. Regular monitoring and proactive management can help prevent the progression to more serious health conditions.
Insulin resistance is a condition in which the body's cells become less responsive to the hormone insulin. Insulin is crucial for regulating blood sugar levels by facilitating the uptake of glucose (sugar) from the bloodstream into cells for energy. When cells become resistant to insulin, more insulin is needed to achieve the same effect, leading to higher levels of insulin in the blood (hyperinsulinemia) and often higher blood glucose levels.
Normal Insulin Function: Under normal conditions, insulin binds to receptors on the surface of cells, triggering a series of reactions that allow glucose to enter the cell.
Insulin Resistance: In insulin resistance, the cells do not respond effectively to insulin. This impairs glucose uptake, leading to elevated blood glucose levels. The pancreas compensates by producing more insulin, but over time, this can lead to pancreatic beta-cell dysfunction and decreased insulin production.
Genetic Factors: Family history and genetic predisposition can increase the risk of developing insulin resistance.
Obesity: Excess body fat, particularly visceral fat (around the abdomen), is strongly associated with insulin resistance.
Physical Inactivity: Lack of regular physical activity contributes to weight gain and can impair insulin sensitivity.
Diet: Diets high in refined carbohydrates, sugars, and unhealthy fats can contribute to insulin resistance.
Hormonal Imbalances: Conditions like polycystic ovary syndrome (PCOS) are associated with insulin resistance.
Inflammation: Chronic low-grade inflammation in the body can interfere with insulin signaling.
Age: Insulin resistance tends to increase with age.
Medications: Some medications, such as corticosteroids, can induce insulin resistance.
Often, insulin resistance itself does not cause noticeable symptoms. However, it can lead to conditions that do have symptoms:
Type 2 Diabetes: Symptoms include increased thirst, frequent urination, fatigue, blurred vision, and slow-healing wounds.
Metabolic Syndrome: A cluster of conditions that occur together, increasing the risk of heart disease, stroke, and type 2 diabetes. These conditions include high blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels.
Type 2 Diabetes: Insulin resistance is a major risk factor for developing type 2 diabetes. As the condition progresses, the pancreas cannot keep up with the increased demand for insulin, leading to high blood sugar levels.
Cardiovascular Disease: Insulin resistance is associated with an increased risk of atherosclerosis (hardening and narrowing of the arteries), hypertension, and other cardiovascular diseases.
Metabolic Syndrome: A cluster of conditions that increases the risk of heart disease, stroke, and diabetes.
Non-Alcoholic Fatty Liver Disease (NAFLD): Insulin resistance can lead to the accumulation of fat in the liver.
Polycystic Ovary Syndrome (PCOS): Insulin resistance is a common feature of PCOS and contributes to the reproductive and metabolic complications of the condition.
Blood Tests: Measuring fasting blood glucose, insulin levels, and Hemoglobin A1c (HbA1c) can help diagnose insulin resistance and its associated conditions.
Oral Glucose Tolerance Test (OGTT): Measures the body’s response to glucose over a period of time after consuming a glucose-rich drink.
Homeostasis Model Assessment of Insulin Resistance (HOMA-IR): A calculation using fasting blood glucose and insulin levels to estimate insulin resistance.
Dietary Changes:
Balanced Diet: Focus on whole grains, lean proteins, healthy fats, and plenty of fruits and vegetables.
Low Glycemic Index Foods: These foods cause a slower rise in blood glucose levels.
Reduce Sugars and Refined Carbs: Minimize the intake of sugary foods and beverages and refined grains.
Physical Activity:
Regular Exercise: Aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity per week, along with muscle-strengthening exercises.
Weight Management:
Lose Excess Weight: Even a modest weight loss (5-10% of body weight) can significantly improve insulin sensitivity.
Medications:
Metformin: Often prescribed for managing blood glucose levels in people with type 2 diabetes and sometimes for those with insulin resistance.
Lifestyle Changes:
Reduce Stress: Chronic stress can worsen insulin resistance.
Improve Sleep: Quality sleep is important for maintaining healthy insulin levels.
Insulin resistance is a condition where the body's cells become less responsive to insulin, leading to higher blood sugar and insulin levels. It is a significant risk factor for type 2 diabetes and other metabolic disorders.

Leptin is a hormone primarily produced by adipose (fat) tissue. It plays a crucial role in regulating energy balance by inhibiting hunger, which in turn helps to regulate body weight. Here are key points about leptin production and its functions:
Primary Source: Adipose Tissue
White Adipose Tissue: The majority of leptin is produced by white adipose tissue, which stores fat and regulates energy balance.
Other Sources: Although adipose tissue is the primary source, small amounts of leptin are also produced by:
Brown Adipose Tissue: Involved in thermogenesis (heat production).
Placenta: During pregnancy, the placenta produces leptin, which may play a role in fetal development and maternal energy regulation.
Stomach: Some leptin is produced in the stomach, particularly in the gastric epithelial cells.
Skeletal Muscle: Minor amounts are produced in skeletal muscle.
Regulation of Appetite and Food Intake:
Leptin acts on the hypothalamus in the brain, where it helps to suppress appetite and promote the feeling of satiety (fullness).
Higher levels of leptin signal the brain that the body has sufficient energy stores, reducing hunger and food intake.
Energy Expenditure:
Leptin increases energy expenditure by stimulating thermogenesis, particularly in brown adipose tissue.
Metabolic Regulation:
Leptin influences various metabolic processes, including glucose metabolism and insulin sensitivity.
Reproductive Function:
Adequate levels of leptin are necessary for normal reproductive function. Low leptin levels, often associated with low body fat, can lead to reproductive dysfunction.
Immune Function:
Leptin has a role in modulating immune responses, particularly in enhancing the function of T-cells.
Leptin Resistance: In many cases of obesity, there is an overproduction of leptin, but the body becomes resistant to its effects. This leptin resistance means that despite high levels of leptin, the brain does not receive the signal to reduce hunger and increase energy expenditure, leading to continued overeating and weight

Estos números son aproximaciones y pueden variar según las condiciones y el estado de la célula.
The most basic unit of the brain
Neurotransmitters are crucial for the proper functioning of the nervous system and play significant roles in our daily lives, affecting everything from mood and cognition to muscle control and pain perception. Understanding the balance and interactions of these neurotransmitters is key to addressing various neurological and psychiatric conditions.
Neurotransmitters are chemical messengers that transmit signals across synapses from one neuron to another in the brain and throughout the nervous system. They play a crucial role in regulating a wide range of physiological processes and behaviors, including mood, sleep, appetite, learning, memory, and muscle contraction.
Acetylcholine (ACh):
Functions: Involved in muscle activation, attention, learning, and memory.
Anandamide:
Functions: Involved in pain, depression, appetite, memory, and fertility.
Dopamine:
Functions: Plays a key role in reward, motivation, pleasure, motor control, and regulation of mood.
Endorphins:
Functions: Natural painkillers that reduce pain perception and promote a feeling of well-being.
Epinephrine (Adrenaline):
Functions: Involved in the fight-or-flight response, increasing heart rate, and mobilizing energy reserves.
GABA (Gamma-Aminobutyric Acid):
Functions: The primary inhibitory neurotransmitter in the brain, reducing neuronal excitability and promoting relaxation.
Glutamate:
Functions: The primary excitatory neurotransmitter in the brain, involved in learning, memory, and synaptic plasticity.
Histamine:
Functions: Involved in immune responses, regulates sleep-wake cycles, and controls appetite.
Norepinephrine (Noradrenaline):
Functions: Involved in arousal, alertness, attention, and the fight-or-flight response.
Oxytocin:
Functions: Plays a role in social bonding, sexual reproduction, childbirth, and the period after childbirth.
Serotonin:
Functions: Regulates mood, appetite, sleep, memory, and learning.
Substance P:
Functions: Involved in pain perception and the regulation of mood and anxiety.
These neurotransmitters are essential for various physiological and psychological functions, and imbalances in their levels or activity can contribute to numerous health conditions.
Synthesis: Neurotransmitters are synthesized from precursor molecules within the neuron.
Storage: They are stored in synaptic vesicles within the presynaptic neuron.
Release: Upon receiving an electrical signal (action potential), neurotransmitters are released into the synaptic cleft.
Binding: Neurotransmitters bind to specific receptors on the postsynaptic neuron, causing a response.
Reuptake/Degradation: After their action, neurotransmitters are either taken back up into the presynaptic neuron (reuptake) or broken down by enzymes.
Neurotransmitter imbalances are often linked to various mental health conditions, leading to the development of medications that target specific neurotransmitter systems (e.g., SSRIs for serotonin in depression, antipsychotics for dopamine in schizophrenia).
Understanding neurotransmitter functions helps in diagnosing and treating neurological disorders and in the development of new therapies.
Neurotransmitters are essential for communication within the nervous system, influencing every aspect of human behavior and physiological function. Their intricate balance and interaction are crucial for maintaining mental and physical health.
An obesogenic environment promotes behaviors that contribute to obesity, such as high-calorie diets and sedentary lifestyles. Addressing these environments requires a multifaceted approach, including policy changes, community initiatives, workplace wellness programs, and individual lifestyle modifications. By creating supportive environments that encourage healthy eating and physical activity, we can combat the rise of obesity and its associated health risks.
Oxilofrine has not been approved for use in the United States but more than 50% of the supplements analyzed contained this substance. Of these, a shocking 43% contained amounts that exceeded the recommended pharmacological dose.
The recommended pharmacological dose refers to the specific amount of a medication that is advised for administration to achieve the desired therapeutic effect while minimizing the risk of side effects and toxicity. This dose is typically established based on clinical trials, research studies, and clinical practice guidelines. It takes into account factors such as the average effective dose, the medication's pharmacokinetics and pharmacodynamics, and the safety profile for the target population.
The recommended dose usually includes:
Starting Dose: The initial amount of medication given to begin treatment, which is often lower to assess the patient's tolerance.
Maintenance Dose: The dose required to maintain the desired therapeutic effect after the initial response has been achieved.
Maximum Dose: The highest amount of medication that can be safely administered without causing significant adverse effects.
For example, in the context of MAOI antidepressants:
The starting dose is the initial amount given to assess the patient's response and tolerance.
The maintenance dose is the dose adjusted based on the patient's response to achieve ongoing therapeutic benefits.
The maximum dose is the highest dose recommended to avoid toxicity and severe side effects.
Healthcare providers determine the appropriate dose for individual patients based on various factors, including age, weight, overall health, the severity of the condition being treated, and the patient's response to the medication.

Afferent signals come from outside stimuli and tell your brain what they are sensing. For example, afferent neurons bring information about temperature, touch, pain, and other sensory experiences to the brain. These signals are integrated and processed in the brain, which then coordinates a response via efferent signals back to the rest of the body
Efferent signals, also known as motor signals, are nerve impulses that travel from the central nervous system (CNS) to the muscles and glands. These signals allow your body to carry out specific actions, such as moving a limb or secreting hormones. In contrast to afferent signals, which convey sensory information to the CNS, efferent signals are responsible for executing commands from the brain and spinal cord.
7-8 hours of sleep: low Ghrelin (full) and high Leptin (got enough food feeling)
Lack of sleep: high Ghrelin (hungry) and low Leptin (unsalisfiable)
Lack of sleep also has been found to affect the risk for chronic diseases such as diabetes, heart disease, and Alzheimer’s, maintaining a regular sleep schedule makes smart sense.

Hydroxycut was voluntarily withdrawn after the FDA received reports of liver toxicity, seizures, and a type of muscle pain called rhabdomyolysis. Although the current Hydroxycut products no longer contain the troublesome ingredients (notably ephedra), medical literature continues to note adverse effects from the supplement.
Oxilofrine has not been approved for use in the United States but more than 50% of the supplements analyzed contained this substance. Of these, a shocking 43% contained amounts that exceeded the recommended pharmacological dose.
When used in combination with lifestyle modification, weight-loss surgery has been proven to be the most effective therapy available, yielding long-term results and better health for people with serious weight problems—particularly those who also suffer from weight-related health issues.
Successful weight-loss surgery may produce these health benefits, among others:
• Diabetes
• High blood pressure
• High cholesterol
• Sleep apnea.
Each of the ailments above significantly improve or completely disappear in roughly 60% to 80% of people who undergo weight-loss surgery. The result of these health benefits: a nearly 30% lower risk of early death.
A 2019 study found that in a group of people diagnosed with both diabetes and obesity, those who had weight-loss surgery significantly lowered their risk of experiencing a heart attack, stroke, heart failure, or similar cardiovascular emergency.
Moreover, a range of other health problems also lessen following surgery, including arthritis, asthma, gastroesophageal reflux disease, infertility, sexual dysfunction, and urinary incontinence.
When combined with a healthy lifestyle, the results of weight-loss surgery can be dramatic. Within the first two years after the procedure, people typically achieve a maximum weight loss of roughly 20% to 35% of their initial body weight.
Over time, weight loss tends to decline, but the loss is often maintained in a range that still produces significant health improvements.
Endoscopic sleeve gastrectomy (ESG) is a minimally invasive weight-loss procedure designed to reduce the size of the stomach using an endoscopic approach, without the need for traditional surgery. Here's an overview of the procedure, its benefits, risks, and other relevant details:
Procedure:
Technique: ESG is performed using a flexible endoscope, which is inserted through the mouth and into the stomach. The endoscope is equipped with a suturing device that allows the surgeon to place sutures in the stomach.
Goal: The sutures create a sleeve or tube-like shape in the stomach, significantly reducing its volume and capacity. This helps in reducing food intake and promoting a feeling of fullness with smaller amounts of food.
Duration: The procedure typically takes about 60 to 90 minutes and is performed under general anesthesia.
Benefits:
Minimally Invasive: ESG is less invasive compared to traditional surgical methods like laparoscopic sleeve gastrectomy. There are no external incisions, which reduces the risk of complications and speeds up recovery time.
Weight Loss: Patients can achieve significant weight loss, typically losing about 15-20% of their total body weight within the first year.
Reversibility: Unlike some surgical weight-loss procedures, ESG can be reversed if necessary, as it does not involve removing any part of the stomach.
Short Recovery Time: Most patients can return to their normal activities within a few days to a week after the procedure.
Risks and Considerations:
Complications: Although rare, potential complications include bleeding, infection, and gastrointestinal perforation.
Follow-up: Regular follow-up with a healthcare provider is essential to monitor progress, manage potential side effects, and provide nutritional guidance.
Lifestyle Changes: Successful long-term weight loss requires adherence to a healthy diet and regular physical activity. ESG is a tool that aids weight loss, but lifestyle changes are crucial for maintaining results.
Eligibility:
Candidates: ESG is typically recommended for individuals with a body mass index (BMI) of 30 or higher who have not had success with other weight-loss methods. It may also be an option for those who are not candidates for traditional bariatric surgery due to medical reasons.
Outcomes:
Weight Loss: Patients often experience substantial weight loss within the first six months to a year following the procedure.
Health Improvements: Weight loss can lead to improvements in obesity-related conditions such as type 2 diabetes, hypertension, sleep apnea, and more.
Dietary Guidelines:
Initial Phase: Patients typically start with a liquid diet immediately after the procedure and gradually progress to pureed foods, soft foods, and eventually regular foods over several weeks.
Long-term Diet: A balanced, nutrient-rich diet with appropriate portion sizes is essential for maintaining weight loss and overall health.
Physical Activity:
Regular exercise is important to support weight loss and overall well-being. Patients should follow their healthcare provider’s recommendations for starting and maintaining an exercise routine.
Support:
Many patients benefit from participating in weight-loss support groups or counseling to address emotional and psychological aspects of weight loss.
Endoscopic sleeve gastrectomy offers a promising option for individuals seeking a less invasive approach to weight loss. However, as with any medical procedure, it is important to discuss the potential benefits and risks with a qualified healthcare provider to determine if it is the right choice for the individual’s specific circumstances.
A tautology is a statement that is always true, regardless of the truth values of its individual components. In logic and mathematics, tautologies play an important role. For example, the statement “Either it will rain tomorrow, or it won’t” is a tautology because it is true regardless of the weather forecast. Similarly, in propositional logic, the expression

It takes just one day to alter the composition of your gut bacteria.
In one Harvard study, researchers found that changes in diet could affect a person’s gut microbes in as little as one day.
Your gut is home to more than 100 trillion microbial cells regulating immune and digestive health and even influencing your mood. That’s more than triple the number of human cells in your body (estimated to be 30 trillion cells
Your microbial cells, or microbes, are incredibly diverse, with up to 1,150 different species that potentially live in your gut.
people struggling with obesity have been found to have gut bacteria that are less diverse and genetically rich than those of lean people. That’s potentially a problem because scientists are also finding that certain microbes may help you stay slim by stimulating the production of hormones that keep you feeling full, such as leptin.
Other gut bacteria may promote weight gain by increasing the fermentation of carbohydrates, encouraging the body to absorb more of their calories.
Still other microbes may prompt the body to store greater amounts of fat.
One reason water may tame your appetite is that it makes you feel more full. It stretches your stomach, sending signals of fullness to your brain.
The timing of drinking water after a meal can depend on individual preferences and digestive health, but here are some general guidelines:
Immediately After Eating:
It's generally safe to drink water right after a meal. It helps in the digestion process by aiding the movement of food through the digestive tract.
During a Meal:
Drinking water during a meal can help with digestion and make swallowing easier. However, some believe that excessive water intake during a meal might dilute digestive juices, potentially slowing down the digestion process.
30 Minutes After a Meal:
Some nutritionists recommend waiting about 30 minutes after a meal before drinking a significant amount of water. This is thought to allow the body to properly absorb the nutrients from the food.
Before a Meal:
Drinking a glass of water about 30 minutes before a meal can aid digestion and help control appetite, which might prevent overeating.
Hydration Needs: Ensure you are meeting your daily water intake needs throughout the day, not just around meals.
Digestive Health: If you have specific digestive issues, such as acid reflux or slow digestion, consult with a healthcare professional for personalized advice.
Individual Preferences: Listen to your body and adjust based on how you feel after eating and drinking at different times.
Ultimately, there is no strict rule, and the best practice is to stay hydrated throughout the day while observing how your body responds to drinking water at different times.
CBT for obesity, therapists help their patients identify and change sabotaging thoughts that perpetuate overeating and weight gain.
At the same time, CBT addresses thoughts and actions related to personal issues such as appearance, self-confidence, and quality of friendships.
The actual weight loss depends on your starting weight and the degree to which your body has adapted to reduced calories by slowing metabolism.
The old “3,500 calories equal 1 pound” rule is wrong
Scientists have uncovered 445 different genes that have been linked to some aspect of obesity. (Open our page on the topic in a new window by clicking here.) https://www.harvardhealthonlinelearning.com/learn/course/lose-weight-and-keep-it-off/getting-started/challenges-of-weight-loss?page=3
Some people do indeed seem to put on weight faster than others, and genetics can play a significant role in this variability. Here are some key points explaining why genetics can influence weight gain:
Basal Metabolic Rate (BMR): Genetic variations can affect an individual's basal metabolic rate, which is the number of calories the body needs to maintain basic physiological functions at rest. A lower BMR can make it easier to gain weight.
Appetite Regulation: Genes can influence hormones related to hunger and satiety, such as leptin and ghrelin. Variations in these genes can lead to differences in appetite and food intake.
Fat Storage and Distribution: Genetic factors can determine how and where the body stores fat. Some people may be genetically predisposed to store fat more efficiently or in specific areas of the body.
Energy Efficiency: Some individuals may have a genetic tendency to use energy more efficiently, meaning they require fewer calories for the same activities, which can lead to weight gain if calorie intake is not adjusted accordingly.
Response to Diet and Exercise: Genetic differences can affect how the body responds to different types of diets and exercise regimens. Some people may lose or gain weight more easily based on their genetic makeup.
Prader-Willi Syndrome: A genetic disorder that causes insatiable hunger, leading to excessive eating and weight gain.
Bardet-Biedl Syndrome: Another genetic disorder that can cause obesity, among other symptoms.
While lifestyle factors such as diet and physical activity are crucial determinants of weight, genetic factors can significantly influence an individual's propensity to gain weight. Understanding the role of genetics can help tailor more effective weight management strategies and provide insight into the biological mechanisms underlying weight gain.

Healthy weight management is not about dieting or counting calories. It’s about turning the skills you’ve learned into habits—eating healthful food that fills you up without loading you down, learning to avoid hunger that sends you on a binge, setting up your kitchen so that you don’t see tempting snacks, savoring your food so that it provides greater satisfaction, and so forth.
