Star ratings reflect scores of 1 to 5 assigned to the Mayo Clinic Diet in eight categories by nutritionists, specialists in diabetes and heart disease, and other diet experts on a ratings panel assembled by U.S. News. (See our Best Diets methodology.) Experts approved of the diet’s nutritional profile, safety, and ability to prevent or treat diabetes or heart disease but were slightly skeptical of its ability to deliver weight loss, citing an absence of rigorous studies on which to base their scores. Still, it earned an overall rating of nearly 4 stars, putting it near the top of our rankings. Below, ratings in all categories and how the experts’ opinions broke down.

In the near-total absence of rigorous long-term studies, experts are reluctant to conclude that any given diet will work over the long haul. Mayo, however, scored higher than many other diets with a score of nearly 3 stars, which is considered “moderately effective.”

Most of our experts thought it was moderately easy to follow. But whether dieters would have the will to stay on track was an issue with some panelists. They were more confident about Weight Watchersand Jenny Craig.

High scores were the norm when the experts put Mayo Clinic’s eating pyramid up against the federal government’s 2010 Dietary Guidelines. It’s “how we all should eat,” one panelist commented.
