Fasting
Fast smarter, not harder.
CombiFast builds a gentle, flexible fasting rhythm around your wake time, bedtime and work — and lets you adjust any day without guilt.
Schedules
Beginner-friendly progression
12:12
Eat 8am – 8pm
The natural overnight fast. The right place for most beginners.
14:10
Eat 10am – 8pm
A modest extension — often just a later first meal or no late snack.
16:8
Eat 12pm – 8pm
A common intermediate rhythm for people who aren't hungry in the morning.
CombiFast never pushes extreme fasting. Signs to slow down: dizziness, poor sleep, irritability or obsessive thoughts about food. Fasting should feel calm.
Morning Reset
A simple fasting-friendly ritual
We don't describe these drinks as “detoxing” the body. Olive oil belongs inside your eating window, not in a strict fast.
