Glucose toxicity and glycation
In the bloodstream, excess glucose can glycate proteins and blood vessel components. The discussion frames this as a driver of impaired enzyme and hormone function and accelerated aging.

Dr Pradip Jamnadas is a cardiologist and expert in metabolic health, known for his work on insulin resistance, fasting, and cardiovascular disease prevention. In this moment, he breaks down the real driver behind modern health issues: insulin resistance. Dr Jamnadas explains exactly what habits keep insulin elevated and causes visceral fat gain, inflammation, and diseases like diabetes. He also reveals the key to reversing this metabolic dysfunction, that you can start implementing today.

Insulin’s role in clearing blood sugar
Insulin is described as the signal that moves glucose out of the blood and into cells, including liver and muscle. The key idea is that insulin rises after carbohydrate intake to normalize blood glucose.
Frequent carb intake and sustained insulin
Eating carbohydrates every few hours repeatedly elevates insulin before it fully returns to baseline. Because insulin lingers longer than glucose, this pattern is presented as keeping background insulin chronically high.
Insulin resistance development
Chronic exposure to high insulin is described as leading to insulin resistance, requiring higher insulin doses for the same glucose-lowering effect. The transcript frames this as a gradual metabolic deterioration over years.
Processed foods and rapid absorption
Low-fiber processed foods are presented as being absorbed quickly, forcing sharper pancreatic insulin responses. This is tied to faster swings in glucose and repeated insulin surges.
Hyperinsulinemia before diabetes diagnosis
The conversation argues that people can have years of high insulin while standard markers like A1C still look normal. It frames diabetes as a late-stage failure after a long prevention window has passed.
Visceral fat as a glucose-driven storage pattern
High insulin is portrayed as directing energy storage toward the abdomen and internal organs rather than evenly distributed weight gain. Visceral fat is emphasized as hard to pinch because it accumulates around organs.
Fatty liver and ectopic fat storage
Insulin is described as pushing glucose into the liver, contributing to fatty liver. The discussion extends ectopic fat to organs like the pancreas and areas around the heart.
Inflammatory nature of visceral fat
Visceral fat is characterized as producing more inflammatory signals than subcutaneous fat. Markers mentioned include IL-6, TNF, and CRP as reflections of systemic inflammation.
Ectopic fat around coronary arteries and plaque risk
The transcript links fat surrounding coronary arteries to inflammation and plaque formation. It notes that imaging such as CT may assess inflammation in perivascular fat.
Screening insulin levels earlier
An argument is made for measuring insulin levels as an early screening tool before overt diabetes. The speaker claims many clinicians do not routinely test insulin or lack familiarity with using it.
Belly-dominant body shape as a clinical clue
A protruding abdomen with comparatively lean limbs is presented as a phenotype suggestive of insulin resistance. The discussion links this pattern to difficulty losing weight due to insulin’s storage effects.
Fasting versus calorie restriction
Fasting is framed as lowering insulin and enabling access to stored energy, while simple calorie restriction is said to slow metabolic rate and increase lean tissue loss. The core claim is that the physiology differs meaningfully between the two.
Fuel use shift during fasting
The first ~12 hours are described as using glycogen from liver and muscle, followed by increased fat mobilization. Visceral fat is presented as an early target during the fat-burning phase.
Ketone production and metabolic effects
Ketones are described as liver-produced fuels derived from free fatty acids when insulin is low. The conversation claims ketones generate fewer reactive oxygen species and act as signaling molecules that alter physiology.
Cyclical ketosis rather than permanent ketosis
The speaker recommends cycling between glucose-based metabolism and ketosis rather than staying ketogenic indefinitely. Maintenance suggestions include time-restricted feeding and occasional longer fasts.
Fasting protocols and progression
Time-restricted eating examples include starting with 12:12, then moving to 18:6 after a few weeks. More aggressive approaches discussed include weekly 48-hour fasts or periodic multi-day fasts for significant weight loss or diabetes reversal.
Applicability of fasting for women
The transcript states most women can fast similarly to men, with exceptions for pregnancy or trying to conceive. It presents fasting as broadly feasible with appropriate context and monitoring.
Extended fasting under medical supervision
Case examples include a 72-day supervised fast with reported improvements in weight and metabolic markers. Another example describes a much longer supervised fast with large weight loss and less excess-skin appearance than expected.
Electrolytes and hunger management during fasting
The speaker suggests using non-caloric fluids and adding electrolytes such as salt to water. For cravings, a small amount of MCT oil is mentioned as an option.
Autophagy and cellular recycling
Fasting and ketosis are linked to autophagy, described as breaking down and removing redundant cellular components. The transcript claims this improves cellular efficiency and function.
Mitophagy and mitochondrial renewal
The discussion highlights mitochondrial turnover during fasting as a reason people may feel better afterward. It links newer mitochondria to improved ATP production and reduced reactive oxygen species.
Fasting, growth hormone, and workout timing
The speaker claims fasting increases growth hormone and recommends exercising near the end of a fast. The suggested approach emphasizes muscle retention and potential muscle gain despite not eating beforehand.
Stem cells, progenitor cells, and vascular repair
Fasting is described as mobilizing stem cells, including endothelial progenitor cells that help repair blood vessel lining. This is positioned as particularly relevant for vascular health and injury repair.
Immune effects attributed to fasting
The transcript claims fasting-related stem cell activity improves immune resilience and reduces common infections. This is presented as an observed benefit among people who fast.
Women, fasted exercise, and training type
A concern is raised that fasted aerobic workouts may be more stressful for some women and could increase muscle breakdown. The response recommends resistance training or HIIT as better-tolerated options in a fasted state.
Exercise recommendations for heart health
The speaker suggests excessive long-duration aerobic training may increase inflammation and correlate with more coronary disease in their clinical experience. Recommended training emphasizes short aerobic sessions plus resistance work and HIIT-style intervals.
HIIT structure and recovery rationale
HIIT is described as short bursts of intense effort followed by equal rest to allow metabolic cleanup. Antioxidant systems like glutathione and superoxide dismutase are mentioned as limiting factors that rest intervals help accommodate.
