Food ChoicesEverything’s on the menu! The new WW is our most holistic approach to weight loss ever, matching you with a customized plan through our new in-depth personal assessment. You’ll also get a list of ZeroPoint™ foods that you don't have to measure or track, giving you freedom in what you eat, while you reach your goals.

Replace two meals a day with a Slimfast shake, smoothie, or bar. You can also have up to three of their 100-calorie snack packs and make one 500-calorie portion-controlled meal, per day.

LivabilityYou’ll learn science-backed techniques that help build lasting habits in a program that’s built to fit into your life. We've added new food, activity, sleep, and mindset tools designed to help make weight loss easier. With an approach that goes beyond food, you’ll see and feel benefits both on and off the scale.

Your portion-controlled meal is the only opportunity to eat non-Slimfast products, and you’re encouraged to eliminate alcohol from your diet.

Social Support

In-person and Virtual Workshops, Coaches, 24/7 Live Coaching, Customer Service, and Connect, an exclusive social network with other members for motivation and inspiration whenever you need it.

Chat with fellow Slimfast customers through a Facebook group.


Our plans start at $4.61/week, plus the cost of food you purchase independently.

Approximately $30/week for the meal replacements, and the snacks cost extra.

Plus, WW is the #1 doctor-recommended weight-loss program based on a 2019 survey by Kantar Health of 500 doctors who recommend weight-loss programs to patients.
