## What is Fasting Center?

Free fasting tracker and timer for intermittent fasting, OMAD, and extended water fasts. No ads, no account needed.

Fasting Center is built around your numbers, not generic guesses. Start a fast, follow 17 fasting stages on a live ring, and see weight, fat loss, and energy use projected from your own body stats, then measured against what actually happened.

TRACK YOUR FAST

ASK YOUR FASTING ASSISTANT

TWO CALCULATORS

- Personalized from your sex, age, height, weight, body fat, and activity

MEASURE YOUR PROGRESS

- Log weight, body fat, waist, ketones, glucose, and blood pressure
