Obesity and Insulin Resistance Over 50

Trace the history of the US food supply from the 1800s to today, showing how refined foods, sugar, and carbohydrates shaped obesity and insulin resistance.

Ancel Keys popularized the diet heart hypothesis linking cholesterol to heart attacks, but the lesson highlights cherry picking and causation vs. correlation. Replacing fat with sugar coincided with obesity.

Explore how politics and industry shaped the FDA food pyramid, the rise of sugar in processed foods, and the shift toward low-fat guidance impacting obesity and insulin resistance.

Define obesity by BMI and recognize its limitations, including visceral fat importance. Explore genetic influences, environmental factors, and the hormonal role of insulin in the obesity epidemic.

Understand how your health care team navigates evolving research, patient care, and staying up to date, with input from doctors, nurse practitioners, and dietitians, to address obesity and insulin resistance.

Learn how carbohydrates drive insulin and blood sugar swings, why refined carbs and fructose fuel obesity and insulin resistance, and how ketosis and ketones offer steady energy and appetite control.

Examine how protein drives insulin response and satiety, and compare red meat, dairy, eggs, and fish, with guidance on ketosis and dairy's impact on obesity and diabetes risk.

Discover how fat and cholesterol are not enemies; explore how LDL particle size, oxidation, and inflammation relate to heart disease, and how reducing sugar while embracing fats supports weight loss.

Discover how insulin and other hormones regulate glucose, fat storage, and satiety, including GLP-1, GIP, cortisol, and leptin, in obesity and insulin resistance.

Examine stimulants and older obesity medications, including fen-phen history and phentermine, highlighting short-term use, potential side effects, addiction risk, and the need for medical monitoring.

Review common non-stimulants and supplements for obesity, including cantref, Contrave, Plenty, orlistat, and berberine. Explain mechanisms, safety considerations, and how access may involve prescriptions or online consultations.

Explore the newest obesity drugs for adults over 50, including GLP-1 therapies, their incretin-based mechanisms, weekly injections, potential weight loss, and insurance considerations.

Examine how statins lower cholesterol but may not prevent heart disease, and how inflammation and insulin resistance influence cholesterol and heart health in obesity and insulin resistance over 50.

Learn how insulin, a key hormone, regulates glucose and fat storage, and how chronic high insulin promotes insulin resistance, elevates the body's set weight, and contributes to obesity.

Understand how insulin resistance drives high blood sugar and glycation, affecting the heart, vessels, liver, eyes, kidneys, and GI tract, with microbiome and incretin effects shaping risk.

Explore how brain insulin resistance impairs glucose uptake and energy, linking to Alzheimer disease, migraines, vascular dementia, and neuropathies.

Insulin resistance links obesity to endocrine and autoimmune diseases, including type 1 diabetes, type 2 diabetes, polycystic ovarian syndrome, thyroid issues, and psoriasis.

Investigate how insulin resistance links obesity to cancer and how a ketogenic diet may influence tumor growth across multiple cancers, with tissue-specific and genetic components.

Establish your baseline for obesity and insulin resistance through formal testing, including fasting glucose, HbA1c, fasting insulin, lipid panel, triglyceride HDL ratio, and cardiometabolic markers, then reassess after weight plateau.

Track weight, log meals and exercise, and monitor glucose and ketones at home to track progress. Use heart rate, blood pressure, and sleep factors to manage insulin resistance over 50.

Learn to cut added sugars and manage net carbs using fiber and sugar alcohols, track with weekly logs, reduce to 50g daily, and replace grains with fats and protein.

Discover how vegan and vegetarian diets risk vitamin and mineral deficiencies, and how targeted supplements—B12, iron, omega-3s, vitamin D3, vitamin K2, iodine, zinc, magnesium—support health; use tests to guide dosing.

Practice intermittent fasting with an 8–10 hour eating window to lower insulin, boost autophagy, and improve metabolic health in obesity and insulin resistance over 50.

Discover how exercise supports health without relying on weight loss, and why high-intensity resistance and variable-resistance training improve insulin sensitivity, bone density, balance, and quality of life.

Explore strategies to lower insulin through a low-carb, high-fat approach, ketogenic ratios, meal timing, labs, and supportive communities for managing obesity and insulin resistance.

Explore online resources, books, and communities that support low-carb, high-fat approaches to obesity and insulin resistance, with cgms, fasting, and brain health insights.
