Individuals use intermittent fasting to lose weight fast. In studies done by the NIH, there was reported weight loss with over 84% of participants — no matter which method of fasting they chose (alternate day fasting, the 8/16 method, or another approach)[*]. Science has shown intermittent fasting to be an efficient weight loss tool, sometimes more than simply cutting calories. In one study, intermittent fasting was shown to be as effective as continuous calorie restriction in fighting obesity[*].
