Your fasting window, planned.

Pick a protocol, tell us when you wake up and work out, and we'll set your eating and fasting windows.

Intermittent fasting schedule

Eating window
8:00 AM – 4:00 PM
Fasting window
4:00 PM – 8:00 AM

Break the fast with the first meal; finish the last meal roughly 1 hour before the window closes. Hydrate freely — water, black coffee, and unsweetened tea won’t break the fast.

FAQ

Good to know

Which protocol should I start with?+

16:8 is the standard entry point — an 8-hour eating window is close to how most people already eat once you skip late-night snacks. Harder protocols (18:6, 20:4, OMAD) work for some but aren't more effective per the current research.

Does fasting break if I drink coffee?+

Black coffee, unsweetened tea, and water don't meaningfully raise insulin and don't break a fast for weight-loss or metabolic-health purposes. Cream, milk, and sweeteners do.

When should I work out?+

For morning workouts, start the eating window an hour post-workout so recovery nutrition lands promptly. For evening workouts, time the last meal to be the post-workout meal and end the window ~2 hours before sleep.
