Dr. Boz on Reversing Insulin Resistance: Diet, Ketones, and Hormones

Understanding Insulin Resistance

• 💡 Insulin resistance is a primary driver of chronic aging, weight gain, and disease, often manifesting in middle age with excess weight, arthritis, and abdominal fat.
• ⚠️ Constantly high insulin levels lead to the body storing excess glucose as fat, growing fat cells, and promoting inflammatory responses like skin tags and potentially cancer growth.
• 🧠 Symptoms include frequent hunger, energy crashes, and difficulty going long periods without food due to fluctuating blood sugar levels.

The Ketogenic Approach to Reversal

• 🎯 The core strategy involves drastically reducing total carbohydrates to 20 grams per day to lower insulin levels.
• 🚀 Exogenous ketones (BHB) can be used initially to signal the liver to start producing ketones, aiding the transition and making the low-carb diet more manageable.
• 🍳 A high-fat, high-protein diet (initially ~80% fat) is recommended, focusing on foods like eggs with extra yolks, bacon, and brisket, while carefully selecting low-carb vegetables.
• 🔑 By lowering insulin, the body can begin to access stored fat for energy, leading to benefits like lower blood pressure, improved sleep, and better energy levels within days.

Hormonal Impact and Fat Metabolism

• ⚡ Insulin dictates resource storage, primarily in the liver and fat cells; when constantly elevated, the body struggles to release this stored energy.
• 💡 As insulin decreases and ketones circulate, fat cells are signaled to release stored resources, including essential hormones like testosterone and vitamin D.
• 📈 For women, insulin resistance can be hardier, requiring meticulous tracking of morning fasting glucose and ketones to manage hormonal fluctuations and fat storage, especially during menopause.

Key Levers for Metabolic Health

• ⏳ Time-restricted eating, particularly avoiding food after sunset, significantly impacts insulin levels and aids in fat release.
• 🏃 Zone 2 training and saunas are highlighted as effective methods for growing new mitochondria and improving overall energy production, with 120 minutes of Zone 2 weekly linked to a 25% reduction in all-cause mortality.
• 💧 Magnesium deficiency is a common culprit for symptoms like restless legs and poor sleep, often exacerbated by the diuretic effect of ketogenic diets; float tanks are recommended for effective magnesium absorption.

Monitoring Progress and Long-Term Health

• 📊 Morning fasting blood glucose and ketone levels are crucial metrics to assess metabolic health and track progress, with normal levels indicating the body is accessing fat stores.
• ⚠️ Consistently high fasting glucose (above 95) or low ketone levels (below 0.5) suggest persistent insulin resistance, requiring adjustments to diet or lifestyle interventions.
• 🍽️ While a ketogenic diet is often the initial focus, long-term metabolic health may allow for some carbohydrates, but maintaining stable insulin levels and avoiding the
