📖 CHAPTERS

1. 1
   0:00 – 13:00

   Visceral Fat, Insulin and the New Face of Heart Disease

   Jamnadas introduces visceral fat as a critical warning sign and frames heart disease as an inflammatory, metabolic process increasingly affecting younger people. He explains what plaques are, how heart attacks are actually caused by plaque rupture and clots, and why treating only the blockage misses the deeper causes.

2. 2
   13:00 – 27:40

   A 28-Year-Old Heart Attack and the Insulin Problem

   Using a 28‑year‑old heart attack patient, Jamnadas illustrates how prediabetes and hyperinsulinemia damage arteries long before diabetes is diagnosed. He describes how he discovered widespread glucose intolerance and later high insulin in supposedly ‘non‑diabetic’ cardiac patients.

3. 3
   27:40 – 41:20

   Glucose, Insulin, and How Frequent Eating Breaks Metabolism

   Jamnadas explains in simple terms how glucose and insulin work, how glycation damages proteins and accelerates aging, and how frequent carb intake locks people into chronically high insulin. He links processed, low‑fiber foods and frequent snacking to insulin resistance and visceral fat.

4. 4
   41:20 – 53:40

   Why Fasting Beats Calorie Restriction for Visceral Fat and Repair

   He draws a sharp distinction between simple calorie restriction and true fasting, arguing that fasting uniquely lowers insulin and triggers a suite of regenerative processes. The conversation covers glycogen depletion, visceral fat mobilization, inflammatory fat types, and how he prescribes various fasting protocols.

5. 5
   53:40 – 1:11:20

   Ketosis, Autophagy, Stem Cells and Fasting Physiology

   The discussion dives into the deeper biology of fasting: ketones as a clean brain fuel, cycling between glucose and ketone metabolism, stem cell mobilization after refeeding, and autophagy/mitophagy as mechanisms for cellular renewal and improved mitochondrial function.

6. 6
   1:11:20 – 1:29:40

   Best Exercise for the Heart: Rethinking Cardio

   Jamnadas challenges the primacy of long, steady‑state cardio, asserting that excessive endurance work increases inflammation and arterial disease in his patients. He outlines a balanced exercise prescription emphasizing short aerobic sessions, body‑weight resistance, and properly structured HIIT, especially timed with fasting.

7. 7
   1:29:40 – 1:47:00

   Gut Microbiome, Leaky Gut and Fatty Liver as Cardiac Risks

   The conversation turns to the gut as the body’s most important interface with the environment. Jamnadas explains how a disrupted microbiome and leaky gut lead to fatty liver, systemic inflammation, and coronary disease, and how he uses coronary calcium scores to track interventions.

8. 8
   1:47:00 – 1:56:40

   Calcium Supplements, Vitamin K2, and Nutrient Gaps

   Jamnadas pushes back on routine calcium supplementation, especially for women, highlighting its association with vascular calcification. He emphasizes hormones (vitamin D3 and K2) over raw calcium, notes the impact of warfarin on K2, and argues that modern diets are too low in K2, necessitating supplementation.

9. 9
   1:56:40 – 2:08:40

   Building a Heart-Healthy Gut: Fiber, Ferments, Sleep and Omega-3

   He offers practical gut‑health guidance: high and diverse fiber intake, fermented foods, and lifestyle habits like sleep and stress management. He highlights our widespread fiber deficiency and links even a single bad night of sleep to next‑day insulin resistance.

10. 10
    2:08:40 – 2:25:20

    Toxins, Mold and Their Surprising Role in Heart Disease

    Jamnadas defines toxins broadly—pesticides, plastics, heavy metals, and especially mold—and describes how modern environments overwhelm liver and gut detox systems. He shares how often he now finds mold toxicity and how treating it can flatten coronary disease progression.

11. 11
    2:25:20 – 2:52:40

    Food Sensitivities, Micro-Inflammation and Rethinking ‘Healthy’ Foods

    The discussion explores non‑traditional drivers of inflammation such as celiac disease and food sensitivities, then tackles common dietary misconceptions around bread, rice, fruit, and cooking methods. Jamnadas offers specific preparation techniques to reduce harm from staple foods like white rice.

12. 12
    2:52:40 – 3:09:00

    Everyday Signs of Systemic Inflammation and Poor Cardiovascular Health

    Jamnadas outlines how he informally assesses cardiovascular risk by looking at patients, then broadens to systemic signs of inflammation like joint pain, skin issues, and mental health. He also connects oral and sinus microbiomes, bad breath, and chronic sinusitis to heart valve and coronary disease.

13. 13
    3:09:00 – 3:20:40

    Caffeine, Palpitations and the Vagus Nerve

    Using the host’s experience of post‑workout palpitations, Jamnadas explains how excessive exercise and caffeine can dysregulate the autonomic nervous system via the vagus nerve. He describes how gut ischemia from over‑exercise impairs vagal tone and outlines how he treats functional arrhythmias by fixing the gut.

14. 14
    3:20:40 – 3:34:20

    Hacking the Vagus Nerve: Breathing, Cold, Humming and More

    This segment details practical ways to stimulate and strengthen the vagus nerve. Jamnadas describes controlled breathing patterns, eye movements, cold application, humming, laughing, and the Valsalva maneuver as simple tools to boost parasympathetic activity and promote cardiovascular and emotional resilience.

15. 15
    3:34:20 – 3:54:20

    Cholesterol, LDL, Statins and the Real Culprit: Small Dense Particles

    Jamnadas reframes cholesterol’s role in heart disease, emphasizing that total LDL is less important than whether LDL particles are small, dense and oxidized. He outlines the five key drivers of damaging LDL, questions blanket statin therapy, and notes risks of statin side effects.

16. 16
    3:54:20 – 4:10:40

    Blood Pressure, Breakfast, and the Doctor’s Own Routine

    He connects hyperinsulinemia and sleep apnea to high blood pressure, suggesting many cases are reversible. The conversation then turns to practical daily eating patterns, his skepticism of breakfast, and details of his personal diet and supplement regimen.

    Screening for Silent Disease and The Importance of Presence

    In closing, Jamnadas lays out the two key tests he thinks every adult over 30 should get, then reflects on loss, limitation and living in the present. He shares his father’s story of outliving grim cardiac prognoses through lifestyle changes and how medicine taught him to focus on the current moment.
