The Mediterranean Diet was picked as the best diet overall for 2021, according to new rankings released by US News and World Report.

An expert panel assessed 39 diets to come up with the final results, examining the evidence behind each diet’s claims. Specifically, they evaluated the likelihood of short-term and long-term weight loss, how easy the diet was to follow, how well it conformed to current nutrition standards, and whether it could be an effective tool for diabetes and cardiovascular disease prevention.

Diets that rounded out the top spots for best overall included the DASH (Dietary Approaches to Stop Hypertension) Diet (#2), the Flexitarian Diet (a mostly vegetarian diet; tied for #2), the WW (formerly Weight Watchers) Diet (#4), the Mayo Clinic Diet (#5), the MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) Diet (tied for #5), the TLC (Therapeutic LifestyleChanges) Diet (created by the National Institute of Health’s National Cholesterol Education Program; tied for #5), and the Volumetrics Diet (food is divided into categories based on energy density; tied for #5).

Diets that made the bottom of the list included the Modified Keto Diet (a less drastic version of the Keto Diet; #35), the Whole30 Diet (#35), the GAPS (Gut and Psychology Syndrome) Diet (a complicated elimination diet; #37), the Keto Diet (#37), and the Dukan Diet (#39), which the experts thought was too restrictive, difficult to follow, and unlikely to result in long-term success.

As for diabetes prevention and management, the Flexitarian Diet (tied for #1), the Mediterranean Diet (tied for #1), the DASH Diet (tied for #3), the Mayo Clinic Diet (tied for #3), and the Vegan Diet (tied for #3) were at the top of the list, while the DASH Diet (tied for #1), the Mediterranean Diet (tied for #1) and the Ornish Diet (#1) were voted best heart-healthy diets.

For those looking for a quick way to drop the extra holiday pounds, the experts chose the HMR (Health Maintenance Resources) Program (delivered meal replacement; #1), the Atkins Diet (tied for #2), and the WW Diet (tied for #2).
