About

Ayuname follows your intermittent fast and explains, hour by hour, what each phase is said to involve. It is educational information: the app counts time, it does not measure anything about your body. THE FASTING PHASES, EXPLAINED • Fed state (0h): digestion under way • Drawing on stores (4h): the body uses what it has stored • Fat burning (12h): a greater use of stored fat is described • Early ketosis (16h): ketone bodies appear • Full ketosis (18h): ketones matter more as fuel • Autophagy (24h): cellular recycling, studied mostly in animals • Prolonged fast (36h) • Three-day fast (72h): usually done with supervision THE PLAN THAT FITS YOU 16:8, 18:6, 20:4, OMAD and long fasts. Change it whenever you want. YOUR FULL HISTORY Every fast, your streaks and months of progress. AN ALERT AT EVERY PHASE We tell you when the timer reaches a new phase. YOUR DATA IS YOURS Works without an account. With one, your history survives a new phone. Free, no ads. Optional premium features. Ayuname is a wellness app: it is not a medical device, it does not diagnose or treat any condition, and it is not a substitute for medical advice. Talk to your doctor before fasting, especially if you are pregnant, taking medication or living with a medical condition.
