Most Replayed Moment: Insulin Is The Reason You're Gaining Fat! How To Lower It Now

[restricted term] resistance and the resulting metabolic dysfunction stem from the cycle of frequent carbohydrate consumption, which triggers repeated [restricted term] release and ultimately damages the body’s ability to process glucose efficiently. This metabolic damage is exacerbated by dietary habits and the prevalence of processed foods lacking fiber.

Cycle of Metabolic Damage From Frequent Carbohydrate Consumption

When sugar or glucose is consumed, the body must quickly remove it from the bloodstream because glucose is toxic at elevated levels. Excessive glucose in the blood leads to glycation, wherein glucose attaches to blood vessel walls, blood components, and hemoglobin, impairing the normal function of chemicals, enzymes, and hormones and accelerating the aging process. Glycated molecules lose their efficacy, and high blood glucose directly contributes to cellular dysfunction and premature aging.

Upon glucose consumption, the pancreas produces [restricted term] to transfer glucose into the liver, muscles, and other tissues, effectively reducing blood glucose levels. In typical eating patterns where food—particularly carbohydrates and glucose—are consumed every few hours, the pancreas is continually stimulated to release [restricted term]. Since [restricted term] stays in the bloodstream for up to four hours, more prolonged than glucose itself, frequent intake perpetuates elevated [restricted term] levels.

Chronic High [restricted term] Causes [restricted term] Resistance, Needing More [restricted term] For Same Blood Sugar Control

Repeated, prolonged exposure to high [restricted term] causes the body to become desensitized—a common hormonal adaptation. The pancreas must then produce increasingly higher levels of [restricted term] to maintain blood sugar control, a phenomenon known as [restricted term] resistance.

This state allows individuals to have normal blood sugar and A1c results, masking underlying metabolic dysfunction while high background [restricted term] silently damages the body’s systems. Early detection of hyperinsulinemia via [restricted term] testing is crucial, as individuals often have many years of high [restricted term] and advancing coronary artery disease even before diabetes is diagnosed. By the time blood sugar control finally fails and diabetes is officially recognized, the opportunity for early intervention and prevention is lost.

Background [restricted term] Drives Visceral and Ectopic Fat Accumulation

Persistently high [restricted term] acts as a storage hormone, directing excess calories into fat storage, especially in visceral areas—the belly and around internal organs. This process results in the typical protruding stomach seen in those with high [restricted term] levels. Visceral fat, located deep within the abdominal cavity and surrounding organs, cannot be pinched like subcutaneous fat.

Metabolically, visceral fat is highly active. Unlike subcutaneous fat, it produces large amounts of inflammatory substances such as interleukin-6 and tumor necrosis factor, contributing to systemic inflammation. Laboratory markers like elevated CRP, interleukin-6, and tumor necrosis factor reveal the inflammatory state associated with excess vi ...

Fasting Preserves Muscle and Removes Visceral Fat Unlike Calorie Restriction

Pradip Jamnadas distinguishes the physiological effects of calorie restriction from those of fasting. When calories are simply reduced, the body perceives a sustained deficit and slows down metabolism, promoting the breakdown of both fat and muscle to conserve energy. This means muscle loss is significant alongside fat loss, as the body tries to utilize every available energy source.

In contrast, fasting triggers a different metabolic response. Once food intake stops, the body first utilizes glucose stored in muscles and liver in the form of glycogen. After about 12 hours of fasting, glycogen stores are depleted, prompting the body to switch to burning stored fat for fuel. The first fat to be mobilized is visceral fat, which is particularly inflammatory and harmful. This process not only targets the body’s most detrimental fat stores but also spares muscle tissue, preserving lean body mass. Skin retraction is improved, so after significant fat loss, there is less loose skin compared to calorie restriction, where muscle and subcutaneous loss can lead to flabbiness and skin laxity.

After 12 Hours of Fasting, the Body Depletes Glycogen, Then Uses Stored Fat For Fuel

Jamnadas describes that after the glycogen is exhausted around the 12-hour mark, fat breakdown begins in earnest. The body produces ketones as a result, moving fat out of storage and utilizing it as the primary energy source.

Choose Fasting Protocols Based On Health Goals and Starting Point

Fasting protocols vary according to the individual’s health status and objectives. For those aiming to reduce visceral fat and improve metabolic health, a basic intermittent fasting protocol is recommended. This starts with a 12-12 pattern: twelve hours of fasting, consuming only non-caloric liquids such as water, black tea, green tea, or black coffee, and twelve hours of eating. This initial phase typically lasts two to three weeks.

More intensive regimens include the 18-6 protocol, where the fasting window expands to 18 hours and the eating window is six hours, still permitting only calorie-free beverages during fasting. This method accelerates visceral fat loss due to prolonged fasting periods and is maintained to achieve targeted fat reduction.

For obese patients with diabetes requiring dramatic metabolic improvements, weekly 48-hour fasts or three-day fasts every nine days are used, sometimes in conjunction with one meal a day (OMAD). Jamnadas cites cases of supervised fasts extending up to 72 days, during which water, black coffee, black tea, electrolytes, and occasionally MCT oil for hunger are consumed. Such approaches can result in diabetes reversal, normalized blood pressure, and substantial fat loss—up to 55-60 pounds—with remarkable skin retraction and improvements in joint and skin health. Even longer supervised fasts have led to the loss of massive body weight without the adverse skin and muscle effects seen with calorie restriction.

Fasting Produces Ketones, a Cleaner and More Efficient Fuel Than Glucose, With Cognitive and Physical Benefits

During fasting, once fat metabolism begins, the liver converts fatty acids into ketones—a superior alternative fuel to glucose. This shift depends on low [restricted term] levels, which enable fats to be liberated from stores. Ketone metabolism is cleaner than glucose, producing less oxidative stress and fewer reactive oxygen species (ROS), thereby reducing cellular damage.

Ketones act not only as fuel but as signaling molecules, inducing brain-derived neurotrophic factor (BDNF) production. This growth factor enhances cognition, stimulates the growth of new brain cells, sharpens reflexes, and improves vision. This evolutionary adaptation ensures heightened performance during periods without food, improving the likelihood of survival and resource acquisition.

Fasting Boosts Stem Cell Mobilization and [restricted term] For Tissue Repair and Muscle Growth

Fasting stimulates the bone marrow to release pluripotent stem cells, which can become various cell types, including muscle and skin cells. This aids in tissue repair and regeneration after the fast. Of particular note are endothelial progenitor cells, which repair the lining of blood vessels—a process enhanced by intermittent fasting and time-restricted f ...

Excessive Aerobic Activity Raises Inflammation and Coronary Risk, Challenging the Belief That More Cardio Is Always Beneficial

Excessive Aerobic Activity Increases Inflammation and Coronary Artery Disease Risk Compared To Shorter, Intense Workouts

Pradip Jamnadas observes that people who perform excessive aerobic activity—such as cycling 100 miles a day, running on treadmills for two hours, or regularly engaging in marathon training—actually experience more inflammation in their bodies and develop greater coronary artery disease than those who engage in short sprints, resistance exercises, or HIIT (High-Intensity Interval Training). This challenges the belief that more cardio is always beneficial for heart health.

Rate-Limiting Step In Repairing Metabolic Damage From Excessive Exercise Is Production of Antioxidants Like Glutathione and Superoxide Dismutase, Meaning Prolonged Exercise Overwhelms Body’s Ability to Manage Oxidative Stress

Jamnadas explains that excessive exercise generates a surge of reactive oxygen species. The rate-limiting step in repairing the resulting metabolic damage is the body’s ability to produce antioxidants, specifically glutathione and superoxide dismutase. When the exercise load surpasses the body’s capacity to produce these chemicals, oxidative stress accumulates, contributing to inflammation and cardiovascular disease.

Balanced Exercise Blends Cardio, Resistance, and Hiit to Boost Heart Health and Metabolism

Limit Aerobic Activity To 15-20 Minutes to Ensure Cardiovascular Endurance Without Excessive Inflammation and Oxidative Damage

Jamnadas recommends including aerobic training for cardiovascular endurance by running or cycling—but for a limited duration, just 15 to 20 minutes per session. This provides the necessary endurance benefits without causing excessive inflammation or oxidative damage.

Resistance Exercises Using Body Weight

He finds that simple resistance exercises, often using one's own body weight—such as floor exercises, planks, leg lifts, and similar movements—work best and are sufficient for most people.

Interval Training Features 30-45 Seconds of Intense Effort and Rest

Jamnadas advocates for HIIT, where the approach involves exercising intensely for 30 to 45 seconds, then resting completely for a similar amount of time. This structure allows the body to address the reactive oxygen species produced during the intense bursts of activity, promoting metabolic recovery and minimizing damage.

Women's Exercise Responses During Fasting Differ Due to Hormonal Sensitivity and Hypothalamic Regulation

Fasted Aerobic Exercise Can Deplete Glucose in Women, Triggering Reproductive Shutdown as the Hypothalamus Prioritizes Pregnancy Defense

Steven Bartlett references Dr. Stacey Sims’ research, noting that women are more hormonally sensitive to fasting and glucose depletion. Prolonged fasted aerobic exercise can drop women’s blood glucose, prompting the hypothalamus to conserve resources for potential pregnancy and sometimes causing menstrual cycle disruption.

Jamnadas agrees that having women run for extended periods (e.g., 40 minutes) while fasting risks excessive glucose depletion and potential muscle breakdown due to the body's protective response.

Women Can Safely Perform Resistance and High-Intensity Interval Training While Fasting Without Muscle Breakdown

According to Jamnadas, most women—including those on fasting programs—can handle resistance and HIIT while fasted without muscle breakdown or glucose-related issues, unless they are pregnant or seeking pregnancy. He observes that women perform just as well as men in fasted HIIT routines and resistance training, both of which emphasize intense muscle work and rest.

Exercise Type, Not Gender, Key in Fasted Hiit and Resistance Training Performance

Jamnadas stresses that exercise type—rather than gender—is the primary determinant of safe and effec ...
