I love this ratings article from U.S.News on the top 20 most popular diets and how healthy they are. The panel of experts included registered dietitians, physicians, and others who specialize in healthy eating behaviors and food science.
I found it interesting that only two of the diets worked for the thousands of people surveyed who had tried the diets: Weight Watchers (which received a 4.4 out of 5 rating, and was ranked #6 for healthy diets), and a modified form of the Atkins diet called Eco-Atkins (ranking #15 and rated 3.1 out of 5 starts).
Click on the name of any diet and it brings you to a page showing how it rates for ease of following, support, nutrition, balance, and other factors.
The number one diet: The DASH diet plan, formulated for preventing high blood pressure. This diet is high in fiber, potassium and calcium; low in sodium and fat; composed of very nutritionally dense foods. It only received 3 stars for how easy it is to follow, but is healthy for virtually anyone who wants to lose weight, control diabetes, control hypertension, and eat for a healthy heart.
