If your weight loss efforts have stalled on the Mediterranean diet, you may find it easier to shed the extra pounds by going vegan and getting rid of all animal products instead of continuing to eat lean poultry and fish.

In a study published in February 2021 in Journal of the American College of Nutrition, people who followed a low-fat vegan diet lost an average of 6.0 pounds (13.2 pounds) over 16 weeks. But when the same people followed a Mediterranean diet for the same time, they usually did not lose weight.

“Since the Mediterranean diet is often advertised for weight loss, it was surprising to see that participants experienced very small changes – if any – when it came to their weight in this diet,” says study author Hana Kahleova, MD, PhD, director of clinical research at the Committee of Physicians for Responsible Medicine in Washington, DC.
