# Fasting 16:8

*Diet · the Undiet catalog · https://undiet.app/diets/fasting-16-8*

Less a diet than a schedule: eating is kept within a set window (a common one is 8 hours). What you eat is up to you.

- Goal: Weight loss, More energy
- Approach: Time-restricted
- Effort: Moderate

## How it works

- Pick an eating window (e.g. 12pm to 8pm)
- Water, black coffee and tea outside it
- No calorie counting required by the method

## What people report

*General, not from Undiet data.*

Mornings are the hard part at first, then it becomes routine.

## The protocol

- Fasting window: 16 hours
- Typical window: 12:00 to 20:00
- Eating window: 8 hours

## In Undiet

Fasting 16:8 is an eating pattern in the Undiet catalog. Marking it records what you are already doing: a self-report marker, never a recommendation. From that day it is a period on your timeline, with your weight and how the days felt drawn across it.
