WeightWatchers is the #1 doctor-recommended weight-loss programme†. Additionally, our diabetes-tailored plan is based on guidelines from the American Diabetes Association and the International Diabetes Federation.

†Based on a 2023 survey by Cerner Enviza of 500 doctors who recommend weight-loss programmes to patients.

Generally, memberships start for as low as £18.95 per month, depending on length of commitment you choose. See offers and pricing here.

We help you lose weight and build healthy habits, one small step at a time. Fad weight-loss diets can be restrictive, and rarely work long term. We have more than 140 publications that show WeightWatchers’ efficacy to help members lose weight and keep it off. See how WeightWatchers stacks up against the competition.

What you eat is up to you—and we’ll show you how to enjoy your favorite foods in a way that gets you to your goals. With WeightWatchers, there are no “good” or “bad” foods—just nutritious and less nutritious ones.

We make it as easy as possible. You’ll get a Points® Budget to “spend” however you want. You’ll track your meals, drinks, and snacks in the WW app and enjoy as many ZeroPoint™ foods as you'd like. Activity can also boost your weight loss (vs. only focusing on food)ᶿᶿ, and every member has access to free, fun, all-level workouts.

Science shows food tracking is the biggest predictor of success—the more you track, the more weight you’ll lose! But we’re all about consistency over perfection: It’s better to track some food most days of the week than every single thing you eat only some days of the week. In other words, perfection is not required. You’ll quickly decide how to approach tracking in a way that works for you. Here are some of our best tracking tips.

These nutritional powerhouses include fruits, veggies, lean protein, whole grains, and healthy fats, so they serve as the foundation of healthy eating and support your overall health. ZeroPoint foods also add bulk and flavor to meals, without costing Points from your Budget, so you don’t have to weigh, measure, or track them—no matter how many you eat in a day.

Our team includes nutrition and behavioural scientists, registered dieticians, clinical researchers, and more. Together they help you overcome common weight-loss hurdles—like stress-eating or late-night snacking—while our exclusive Points system makes nutrition easier—so easy that healthier eating will feel like second nature. After you sign up, you’ll answer a few questions to get a plan personalised for you, and build healthy habits with proven behavior change techniques.

Our Workshops (or Meetings, back in the day) are coach-led group sessions held in a Studio location or online. You don’t need to go, but the extra support can ramp up your results: Workshop members lose two times more weight than those who DIY.ᶿ Workshops offer unlimited accountability, and give you a sense of belonging alongside coaches and members who really get it.

Our current weight-loss programme uses advanced nutrition and behavioural science for our most personalised plans yet, and factors in more nutritional data, like added sugars, fiber, and unsaturated fats, to guide you toward the healthiest foods. It also gets to know who you really are, to build a nutrition plan that makes weight loss livable and easier. Plus, we’ve added hundreds of ZeroPoint foods you never have to measure or track.

People following the WW weight-loss programme can expect to lose 1 to 2 pounds per week.
