One Weight Watchers point equals 50 calories. However, on this diet, not all calories are treated the same, according to DrFuhrman.com, which states that Weight Watchers adds points for high fat and fiber content.
Weight Watchers also rewards activity points, which allow for additional food consumption based on physical activity. The company's weight loss plan is built on the concept that burning more calories than you take in will result in weight loss. Weight Watchers says its Points System emphasizes healthy, filling foods such as lean meat, fruits and vegetables, and whole grains, along with plenty of water intake and physical activity.
