• Dr. Jamnadas frames belly-focused visceral fat as a major warning sign because he sees it as inflammatory and tied to insulin resistance.
• He says frequent sugar, refined carbohydrate, and processed food intake keeps insulin elevated and can push people toward heart disease before they realize it.
• He introduces fasting as a tool for lowering insulin and mobilizing visceral fat once stored glucose has been used.
• The opening previews his wider prevention lens: sleep, mold, excessive aerobic exercise, calcium supplements, fruit intake, and rice preparation all come up as cardiovascular risk factors.

• Dr. Jamnadas tells Steven that cardiology is not only blocked arteries; it also includes heart muscle disease, valves, peripheral circulation, and microvascular dysfunction.
• He explains that a heart attack often happens when an inflamed plaque ruptures and a blood clot seals the artery, not simply because plaque slowly fills the whole pipe.
• He uses a 28-year-old heart attack patient to show that visceral fat, fatty liver, and high insulin can exist before a formal diabetes diagnosis.
• His prevention approach is to ask why plaque formed, why the plaque became unstable, and why the blood was prone to clotting.

• Dr. Jamnadas explains that glucose is needed for energy, but too much glucose in the bloodstream glycates proteins, enzymes, hormones, and blood vessel structures.
• He says insulin clears glucose from the blood, but eating carbohydrates every few hours can keep insulin high because insulin stays elevated longer than glucose.
• He warns that normal A1c or glucose can hide years of hyperinsulinemia before diabetes is finally diagnosed.
• He connects chronically high insulin with fatty liver, visceral belly fat, inflammation, and difficulty losing weight.

• Dr. Jamnadas says he often starts people with 12 hours fasting and 12 hours eating, then moves toward an 18-hour fast with a 6-hour eating window.
• For major weight loss or diabetes reversal, he discusses longer fasts, but he presents those as medically supervised interventions.
• He distinguishes fasting from calorie restriction because fasting lowers insulin and changes the body's physiology rather than only reducing calories.
• He says the first 12 hours use glycogen, then the body begins drawing from fat stores, including visceral fat.

• Dr. Jamnadas explains ketones as an alternate fuel the liver makes from fat when glucose is low and insulin has dropped.
• He tells Steven that people are designed to switch between glucose use and fat-derived ketone use rather than stay in one fuel state forever.
• He presents ketones as cleaner fuel in the sense that they create fewer reactive oxygen species during mitochondrial energy production.
• He links fasting and ketogenesis with brain-derived neurotrophic factor, better repair signaling, and improved metabolic efficiency.

• Dr. Jamnadas says fasting and refeeding can mobilize stem cells, including immune-related cells and repair-oriented progenitor cells.
• He is especially interested in endothelial progenitor cells because they help repair the lining of blood vessels.
• He says fasting raises growth hormone, which is why he often has patients exercise near the end of a fasting window.
• He favors resistance training near the peak of a fast as a way to support muscle while insulin is low.

• Steven raises the concern that women may respond differently to fasted workouts because of glucose and hormone sensitivity.
• Dr. Jamnadas answers by separating long aerobic exercise from resistance exercise and high-intensity intervals.
• He is more cautious about long fasted treadmill-style cardio than he is about resistance training.
• He says women in his practice have done well with HIIT-style work that alternates intense effort with full rest.

• Dr. Jamnadas says he cycles patients out of strict ketosis because the goal is metabolic flexibility, not permanent ketosis.
• After a weight-loss goal, he describes time-restricted feeding such as 18/6 as a maintenance pattern.
• He explains autophagy as the cell recycling redundant parts when new parts are not coming in.
• He connects fasting with mitophagy, meaning mitochondrial recycling that can leave cells producing energy more efficiently.

• Dr. Jamnadas says he sees more inflammation and coronary artery disease in people who chronically overdo long aerobic exercise.
• He still values some aerobic training for endurance, but suggests keeping it modest rather than making it the whole program.
• He highlights short sprints, resistance exercise, bodyweight movements, and HIIT as more useful patterns for many patients.
• He emphasizes rest intervals so the body can clear the metabolic byproducts created by hard exercise.

• Dr. Jamnadas tells Steven that the gut is a major border between the outside world and the body, and that a damaged gut lining can drive inflammation.
• He links leaky gut with bacterial wall products reaching the liver and contributing to fatty liver.
• He says fatty liver can come from alcohol, leaky gut, or excess insulin converting glucose into fat.
• He follows coronary calcium scores over time and wants treatment to stop the score from rapidly rising.
• He says real food, more fiber, microbiome repair, and nutrition support can help flatten coronary calcium progression in his patients.

• Dr. Jamnadas says he stops calcium supplements in his cardiac patients and focuses instead on vitamin D3 and K2.
• He explains D3 as helping calcium absorption and K2 as helping keep calcium from building up in the wrong places, including blood vessels.
• He stresses fiber because beneficial gut bacteria eat fiber and produce helpful metabolites.
• He recommends fermented foods such as kefir because they provide bacteria and postbiotics, including vitamin K2 and short-chain fatty acids.
• He says variety matters, aiming for many different plant fibers across the week rather than the same narrow food list.

• Dr. Jamnadas says sleep is essential for repair, gut microbiome balance, vagus nerve function, and insulin sensitivity.
• He tells Steven that one bad night of sleep can make a person insulin resistant the next day.
• He defines toxins as exposures the body should not have to process, including pesticides, herbicides, plastics, PFAS, BPA, alcohol, heavy metals, and mold.
• He says the gut and liver are central detox systems, but modern exposure levels can overwhelm them.
• He treats mold exposure as a real source of chronic low-grade inflammation and says it can affect cardiovascular health.

• Dr. Jamnadas says that when a healthy-looking person develops coronary disease, there is usually a hidden source of inflammation if you dig deeply enough.
• He lists mold, leaky gut, food sensitivities, celiac disease, pesticides, herbicides, toxins, and nutritional deficits as examples to investigate.
• He tells Steven that the fastest route to his operating table is nutrient-deficient processed food: refined wheat, cookies, cakes, fast food, packaged foods, artificial sweeteners, and sugary drinks.
• He says white rice should be soaked, cooked with extra water, cooled, and reheated to reduce arsenic exposure and create more resistant starch.
• He warns that blackened, fried, and overcooked foods create advanced glycation end products that drive inflammation.
• He calls out excessive fruit and vegetable seed oils as foods people may think are healthy but that can worsen fatty liver, omega-6 imbalance, and inflammation when overused.

• Dr. Jamnadas tells Steven he looks beyond BMI and pays close attention to where weight is carried.
• He says a protruding belly is a problem because it suggests visceral fat, which he sees as metabolically dangerous.
• He links joint pain, rheumatoid symptoms, psoriasis, and skin disease with underlying inflammation in many patients.
• He describes diet change, gut repair, intermittent fasting, exercise, stress management, and sleep as connected ways to reduce that inflammatory load.

• Dr. Jamnadas says the microbiome runs from the mouth through the gut, and each region can influence cardiovascular risk.
• He treats poor dental hygiene and harmful oral bacteria as serious because he links them with valve disease and coronary calcification.
• He says chronic sinusitis is ongoing inflammation, and fungal sinusitis can be another mold-related inflammatory source.
• His broader point is that coronary disease is affected by the whole lifestyle environment, including food, oral health, sinus health, gut health, and mental state.

• Dr. Jamnadas compares caffeine with adrenaline and says too much caffeine can keep the body in a constant sympathetic state.
• He separates moderate coffee from heavy caffeine use because coffee also provides polyphenols and soluble fiber for gut bacteria.
• He says palpitations are urgent when someone has underlying structural heart disease, blocked arteries, cardiomyopathy, or valve disease.
• When a young otherwise healthy person has palpitations, he often looks for sympathetic-parasympathetic imbalance, stress, leaky gut, and vagus nerve dysfunction.

• Dr. Jamnadas says extreme exercise can divert blood from the gut to the muscles and temporarily impair the gut and enteric nervous system.
• He describes the vagus nerve as the body's major communication line between the brain, gut, heart, lungs, and repair systems.
• He says modern life keeps people in sympathetic fight-or-flight and does not give enough parasympathetic rest-and-repair time.
• He recommends vagus nerve practices such as four-count inhale and eight-count exhale breathing, humming, singing, laughing, cold stimulation, and gentle eye or neck techniques.
• He links better vagus nerve function with improved heart-rate variability, blood pressure, inflammation markers, clotting tendency, and repair.

• Dr. Jamnadas explains LDL as a cholesterol-carrying lipoprotein but says the real concern is damaged, oxidized, small dense LDL.
• He identifies glucose, omega-6 excess, advanced glycation end products, toxins, and leaky gut as drivers of damaged LDL particles.
• He explains plaque formation through oxidized LDL damaging the endothelial lining, macrophages consuming that LDL, and foam cells becoming part of plaque.
• He is nuanced on statins: they lower LDL, but he wants clinicians and patients to monitor side effects and focus on whether cardiovascular events are actually being reduced.

• Dr. Jamnadas says high insulin prevents blood vessels and capillaries from dilating properly, which can contribute to high blood pressure.
• He says he looks for causes such as sleep apnea and hyperinsulinemia rather than accepting essential hypertension as unexplained.
• He tells Steven that most adults can skip breakfast and eat lunch and dinner to create an 18-hour fasting window; if breakfast is necessary, he suggests skipping dinner instead.
• He describes his own pattern as small amounts of carefully sourced meat or fish, vegetables, lentils and curries, kefir, inulin, omega-3, D3, K2, magnesium, vitamin C, nattokinase, and probiotics.
• He emphasizes sourcing, such as grass-finished animal foods, because he is trying to reduce omega-6 and toxin exposure.

• Dr. Jamnadas says the key question is how to screen for inflammation and coronary artery disease before a crisis.
• He recommends a coronary calcium score for adults over 30 who have concerns; a zero score means no coronary calcium, while a positive score means atherosclerosis is present.
• He says a positive coronary calcium score should lead to a prevention-focused cardiology plan.
• He recommends inflammatory blood work that looks beyond basic cholesterol, including LDL particle size, oxidized LDL, CRP, interleukin-6, tumor necrosis factor, A1c, and glucose.
• He tells Steven that brain fog, memory decline, depression, sleep disturbance, and body changes can be signs of inflammation even when someone does not feel obviously sick.

• Dr. Jamnadas closes by describing how his father changed diet and lifestyle after bypass surgery and lived decades longer than expected.
• He uses that story to reinforce his belief that simple changes can improve health span even when heart disease is already present.
• He also acknowledges the limits of medicine and the emotional weight of wondering whether more could have been done.
• He says learning to live in the present moment helps people act with courage instead of being trapped in regret or future worry.
