How to make 16:8 work
The window is arithmetic; sticking to it is habit. Put the eating window over the part of the day you are most social or most active, keep water and black coffee flowing during the fast, and don\'t use the window as licence to eat more than your day needs — fasting is a schedule, not a diet. What and how much you eat between 18:00 and 02:00 still decides your results, so pair this with the TDEE and macro calculators.

Frequently asked questions
What is my eating window on 16:8 starting at 18:00?
Your eating window runs 18:00 to 02:00 — 8 hours — and you fast the other 16 hours, from 02:00 until 18:00 the next day.
What can I drink during the fast?
Water, black coffee and plain unsweetened tea are the usual choices that keep the fast intact. Anything with calories — milk, sugar, juice — ends the fast, so a splash of milk in coffee counts as breaking it.
Is 16:8 good for beginners?
Yes — 16:8 is one of the gentler schedules and a sensible place to start. Ease in over a week rather than jumping straight to the full fast.
Other schedules
General information, not medical advice. Fasting is not for everyone — if you are pregnant, underweight, or have a health condition, talk to a doctor first.
