Mixed outcomes from a complete of 130 clinical trials present that intermittent fasting may assist cut back weight, body mass index (BMI), physique fats, “dangerous” cholesterol, fasting blood sugar, and blood pressure, amongst different danger elements related to weight problems.

The opposite, known as the “5:2 Food regimen” is analogous, however entails 2 days per week of zero or very low-calorie consuming and 5 days of regular consuming.
Much less useful have been time-restricted consuming, involving fasting 12-24 hours per day, and “zero calorie alternate-day fasting,” the place no meals is consumed each different day.
