Fasting, exercise, and diet each do something the others can't. Here's what makes extended fasting unique — and why all three work better together

Discover what extended fasting does to your brain — from ketone-powered energy and reduced neuroinflammation to increased BDNF, autophagy, and mental clarity.

Extended fasting can dramatically improve blood sugar regulation and insulin sensitivity. Here’s my real Dexcom CGM data and fasting results.

How fast do ketones rise during fasting? In my 7-, 9-, and 10-day water fasts, I tracked how quickly I entered ketosis and what made the biggest difference. Turns out, movement early in the fast helps you reach deep ketosis faster — and burn more fat along the way.
