Your fasting
window
Start your fast, watch the clock, and see exactly what your body is doing — hour by hour, from the first switch to fat-burning all the way through to autophagy.
Fed State
What happens, hour by hour
- 0h
Fed State
Digesting and absorbing your last meal. Insulin is high; the body runs on incoming glucose.
- 4h
Switching Over
Blood sugar settles, insulin falls, and the body begins reaching for stored energy.
- 12h
Fat-Burning Begins
Glycogen runs low and fat becomes the main fuel. Early ketones appear.
- 16h
Autophagy Rising
Cellular “clean-up” steps up — worn-out components get recycled. The signature fasting window.
- 18h
Deep Ketosis
Ketones climb, mental clarity often peaks, inflammation signals settle.
- 24h
Renewal
Growth-hormone support and deeper autophagy. A full day of metabolic rest.
Fasting hits harder with a guide
Dr. Anirudh’s 72-hour guided water fast — daily live sessions, a private community, and a doctor watching over the whole reset.
Educational only — not medical advice. Fasting isn’t right for everyone: if you’re pregnant or breastfeeding, underweight, diabetic on medication, or have a history of disordered eating, please speak with Dr. Anirudh before starting.
