Intermittent fasting is unlikely to lead to greater weight loss in overweight or obese adults than traditional dietary advice or doing nothing, a new review appearing in the Cochrane Database of Systematic Reviews finds.

In 2022, 2.5 billion adults were overweight. Of these, 890 million were living with obesity.
