Fasting tracker

The fasting tracker in LifeWell is a timer for an eating window, plus the history of the windows you have kept. Track intermittent fasting windows with built-in support for popular protocols like 16:8, 18:6, 20:4, and OMAD. Start a fast timer, monitor elapsed time, and review your fasting history and streaks. The protocols are presets for a duration, nothing more — the app does not decide whether fasting suits you, does not adjust the window for you, and does not know what you ate when the window opened.

Questions

Which fasting protocol is best for beginners?

The 16:8 protocol (16 hours fasting, 8 hours eating) is the most approachable for beginners. It typically means skipping breakfast and eating between noon and 8 PM.

Can I drink water during a fast?

Yes. Water, black coffee, and unsweetened tea are generally considered acceptable during fasting periods. The tracker focuses on food intake timing.

Is intermittent fasting safe?

For most healthy adults, intermittent fasting is considered safe. However, it is not recommended for pregnant or breastfeeding women, children, or people with certain medical conditions. Consult a healthcare provider before starting.
