Ramadan Fasting (RF) protocols (28-30 days) have insufficient evidence to draw definitive conclusions regarding their effects on body weight, composition, or glycemic control compared to Time-Restricted Feeding.
Do not rely on Ramadan Fasting as a proven, standalone strategy for weight loss or metabolic health improvement based on current scientific evidence. The data is too sparse to recommend it over established methods like TRF.
LimitedRefutesVERY_LOW confidence
Concerning RF, only two studies were available and thus, conclusions were not drawn.
Why this rating
Only two RCTs were found, making any conclusion weak.

- Time-restricted feeding (TRF) with an 8-hour eating window (16:8) produces moderate weight loss in individuals with overweight or obesity, with effects potentially exceeding 5% of initial body weight when combined with caloric restriction.Good
- Time-restricted feeding (TRF) improves insulin sensitivity and glycemic control (including reduced glucose variability and HbA1c) in individuals with overweight or obesity, independent of significant weight loss in some studies.Good
