What does the evidence say about the effectiveness of intermittent fasting compared to regular calorie restriction?
A 2022 randomized controlled trial published in the New England Journal of Medicine found no significant differences in weight loss, body fat percentage, or metabolic markers between time-restricted eating and unrestricted calorie-matched eating after 12 months. This indicates that the metabolic benefits attributed to fasting are largely due to the caloric restriction it enforces, rather than the fasting interval itself.
