9 Health Benefits of Fasting, Backed by Science

Intermittent fasting is not a diet. It does not tell you what to eat but when to eat. You consciously fast during a specific period, and you eat at certain times of the day. Intermittent fasting is not only a way to lose weight but also to improve your health.

Intermittent fasting is excellent for losing weight because it creates a caloric deficit (1). 

  • Calorie-input: You decrease the calories you eat by skipping one or more meals.
  • Calorie-output: You increase the number of calories you burn by increasing your metabolism by up to 14% (23).

Besides, intermittent fasting can drastically lower your insulin levels (5), which is beneficial if you want to lose weight and also helps prevent type 2 diabetes.

Research has shown that you can lose 3% to 8% of your weight in a period of 3 to 24 weeks (6).
