And the winner is…As with any diet, success will be dictated mostly by adherence. When it comes to weight loss, ADF is likely to lead to the most rapid success, but sustaining weight loss in the long term may be aided by the less intense 5:2 approach.There is some evidence that adherence could be greater in TRE, as completely restricting food intake may be easier for some people than severely restricting it. In this sense, research suggests that skipping dinner may be better for health than skipping breakfast.It’s important to note that most research suggests that intermittent fasting is no better than traditional methods of dieting. But intermittent fasting regimens that have prolonged periods of fasting, such as TRE with shorter feeding windows and 5:2 with two consecutive very low calorie days, may provide additional health benefits.
