Confused about what diet is best and most effective? Consumer Reports has done the legwork for you. In fact, the magazine has taken an objective and research-based look at some of the most popular diets on the market, ranking them by effectiveness over the short and the long term. While the popular Volumetrics plan won four years ago (the last time they did this head-to-heat diet off), this year it was Jenny Craig who favorably tipped the scale, winning the title of "best diet." Which this isn't a huge surprise because Volumetrics, a high-bulk and low-calorie food plan, is now part of Jenny Craig.

Based on a scoring system, Jenny Craig won with a total of 85 points, which was 22 better than second-place finisher Slim-Fast. Weight Watchers came in third at 57 points, and Atkins came in last with a score of 48. Jenny Craig was lauded for the 2010 Journal of the American Medical Association study that showed that 92 of participants stuck with the Jenny Craig program for two years, and at the end of that time, weighed an average of about 8 percent less than when they started. Consumer Reports called this "a remarkable level of adherence."

Should you try this diet? While Jenny Craig does give you the support of weekly counseling sessions (love that!), it still relies heavily on pre-packaged meals, which can get boring - quick. The only perfect diet and lifestyle in our opinion? A healthy eating plan with regularly activity that you like to do and can maintain!
