WW uses a simplified calorie-counting system that is personalized based on your age, weight, height, and sex to help you lose weight in a healthy way. You track everything you eat and drink, as well as your workouts, on the app or website. Depending on your goal, you’re allotted a specific number of what WW calls “SmartPoints” each day. Every food and drink has a corresponding SmartPoint value, with the healthiest foods being freebies with no points at all—it’s basically calorie counting with way less complicated math. Saturated fat and sugar drive the SmartPoints value up, while protein drives it down.
The app includes a customized food plan, food, activity, water, sleep, and weight trackers. It also has barcode scanner, recipe database, and all-level workouts, including running, with 24/7 live coaching.
