Best weight-loss program overall
Easily outshining the competition, Weight Watchers promotes a sensible diet, exercise and a positive attitude, and has been proven effective in a variety of scientific studies. The program can also be customized for those with special dietary needs, including gluten intolerance. In-person group meetings are the plan's cornerstone but they aren't mandatory; online support is available, as well (*Est. $19 per month). Dieters must keep strict track of their calorie intake via a point system, which puts more focus on whole foods and fiber-rich fruits and vegetables. Overall, Weight Watchers has a vastly better record than any other diet plan. Weekly fees vary based on location, but average $13 to $15 per week.
