US News evaluated 38 of the most popular diets based on how easy they are to follow, their ability to produce short- and long-term weight loss, nutritional completeness, safety, and their potential to help prevent or manage diabetes and heart disease, and chose the best one in nine different categories.

Tried and true, Weight Watchers was rated the best diet choice in three out of the nine categories.
