by Editors of U.S. News & World Report
Our AssessmentEvery year, U.S. News & World Report rounds up the top diets in a variety of categories. They consult experts in diet and nutrition, and offer overviews as well as a detailed analysis of each diet. Those that receive a "best" ranking overall are effective for weight loss as well as relatively easy to follow, offer appropriate nutrition, and help reduce the risk of diabetes and heart disease.
Diet Plans Ratings
Our AssessmentFour commercial weight-loss programs, Weight Watchers, Medifast, Jenny Craig and Nutrisystem, and nine do-it-yourself plans are evaluated and rated. Ratings are based upon feedback from 9,376 subscribers. Each plan receives an overall score for initial weight loss, maintenance, calorie awareness, food variety, inclusion of fruits and vegetables, and exercise integration and encouragement.

A Dietary Quality Comparison of Popular Weight-Loss Plans
by Yunsheng Ma, M.D., Ph.D, et al.
Our AssessmentThis study compares seven weight-loss plans -- "The New Glucose Revolution," Atkins Diet, South Beach Diet, Dean Ornish's "Eat More, Weigh Less," the Zone Diet, Weight Watchers and the USDA 2005 Food Guide Pyramid -- using the dietary guidelines of the Alternate Healthy Eating Index (AHEI) to determine which is the most healthful and best able to prevent cardiovascular disease.
Comparison of the Atkins, Zone, Ornish, and LEARN Diets for Change in Weight and Related Risk Factors Among Overweight Premenopausal Women
by Christopher D. Gardner, et al.
Our AssessmentMore than 300 overweight/obese premenopausal women are randomly assigned to follow the Atkins Diet, Zone Diet, LEARN or Dean Ornish's "Eat More, Weigh Less" diet for 12 months. Weight loss is greatest in the Atkins Diet group but not statistically different from subjects following the Zone, LEARN and Ornish diets. Health outcomes -- including lipid profiles, triglycerides and blood pressure (for the Atkins Diet) -- are comparable to or more favorable than the other diet groups.

by Michael L. Dansinger, M.D., et al.
Our AssessmentThis study randomly assigns 160 overweight individuals to the Atkins, Dean Ornish's "Eat More, Weigh Less," Weight Watchers or Zone diets. At the one-year mark, 25 percent of participants who stuck to their diets lost more than 5 percent of their body weight, regardless of which plan they followed.

Effect of a Free Prepared Meal and Incentivized Weight Loss Program on Weight Loss and Weight Loss Maintenance in Obese and Overweight Women: A Randomized Controlled Trial
by C.L. Rock, et al.
Our AssessmentIn a randomized controlled trial, more than 440 overweight or obese women either participate in a two-year Jenny Craig protocol or receive "usual care," which includes two individualized weight-loss counseling sessions and monthly contacts. The Jenny Craig protocol includes prepackaged meals, in-person or telephone-based one-on-one counseling for weight loss, and increased physical activity. While the Jenny Craig dieters lost 7.9 percent of their initial weight after two years, the usual-care control group lost 2.1 percent of their initial weight.
Determining the Effectiveness of Take Off Pounds Sensibly (TOPS), a Nationally Available Nonprofit Weight Loss Program
by Nia S. Mitchell, et al.
Our AssessmentThis study evaluates Take Off Pounds Sensibly (TOPS), a nonprofit weight-loss program that's available at a much lower cost than commercial diets. The study examines results for more than 40,000 members, and finds that those who stuck with the program for a year or more lost about 6 percent of their body weight. "TOPS is associated with moderate weight loss among participants who remain in the program for at least one year," the researchers conclude, adding that it provides "similar results" to commercial weight-loss programs. However, experts acknowledge that trials comparing TOPS to commercial plans like Weight Watchers are still needed.

by Iris Shai, RD, Ph.D, et al.

The Mediterranean and low-fat groups are limited to 1,500 to 1,800 calories per day, but the low-carbohydrate group can consume unlimited calories. Dietitians meet with each group throughout the study both in person and over the phone. After two years, subjects on the low-carb and Mediterranean diets lost more weight than those eating low-fat.

by Contributors to Epinions.com
Our AssessmentEpinions.com's material on diet programs consists of minimal summaries of each and anecdotal ratings from users. Although these aren't as credible as head-to-head comparisons, they do provide individual experiences that may be helpful to read. A number of diet plans attract a huge number of reviews, including Weight Watchers and Slim-Fast. However, most are several years old.
