Intermittent fasting works mainly when it reduces total intake — not because magic happens during fasting hours. Head-to-head studies often show similar weight loss versus daily calorie limits.
Who should be careful
- Pregnant or breastfeeding people
- History of eating disorders
- People on medications that require food
- Athletes with high training loads — unless coached
If you try it
A 10–12 hour overnight fast — finishing dinner by 8 p.m. and eating breakfast after 8 a.m. — is a gentle entry point many people already approximate.
Healthy eating does not have to be perfect. MealCoach.ai and Coach Kibo help you build better meals, understand what works for your body, and stay consistent — without shame or endless calorie math.
