WHAT IT’S REALLY ABOUT

Insulin, ketones, and habits: a new blueprint for fat loss

Dr. Benjamin Bikman argues that insulin control, not calorie counting, should be the central focus of sustainable fat loss and metabolic health. He explains how chronically high insulin drives fat storage, hunger, and brain fog, and why lowering carbohydrates can increase metabolic rate, satiety, and access to stored fat via ketones. The discussion covers ketogenic diets, exogenous ketones, GLP‑1 drugs like Ozempic, creatine, sleep, stress, and practical daily routines that fit real life. Throughout, Bikman stresses flexibility (keto isn’t the only path), the importance of preserving muscle, and using tools like CGMs, labs, and simple behavioral shifts to make 2026 a genuinely transformative health year.

IDEAS WORTH REMEMBERING

5 ideas

Prioritize lowering insulin, not just cutting calories, to lose fat

Calorie restriction alone often leads to hunger and rebound weight gain; lowering insulin by reducing refined carbs lets you eat adequate protein and fat, access stored body fat, and feel less hungry while shrinking fat cells.

Use carb control and meal timing to stabilize energy and cravings

Minimize carbs at breakfast and lunch, eat a large protein‑ and fat‑rich lunch, and avoid late‑night snacking so you don’t go to bed hyperglycemic—this improves sleep, reduces evening cravings, and supports better metabolic health.

Leverage ketones for brain, heart, and appetite benefits

In low‑insulin states (fasting or low‑carb), the liver turns fat into ketones, which fuel the brain and heart efficiently, reduce anxiety and hunger, and may aid conditions like depression, migraines, epilepsy, and cognitive decline.

If you use GLP‑1 drugs, treat them as temporary training wheels

Bikman suggests low‑dose, time‑limited GLP‑1 use, paired with low‑carb coaching, to break carb cravings and establish new habits, rather than long‑term reliance that can erode muscle and eventually lose effectiveness.

Protect and build muscle with protein, resistance training, creatine, and omega‑3

During weight loss, you risk losing lean mass; lifting weights, eating sufficient protein, supplementing creatine and omega‑3s help preserve or build muscle, which is crucial for metabolism, longevity, and quality of life.
