WeightWatchers is a weight loss program built around a Points system that assigns every food a numerical value based on its nutritional profile. Instead of counting calories or eliminating food groups, you spend a personalized daily budget of Points, eating whatever you want as long as you stay within your allowance. The program has been around for over 60 years and consistently ranks among the top weight loss diets in annual expert reviews.
How the Points System Works
Every food gets a Points value calculated from its nutritional makeup. Foods that are high in carbohydrates, sugar, and saturated fat while being low in fiber score higher on the Points scale, meaning they cost more of your daily budget. Foods rich in protein and fiber score lower. The system is designed to nudge you toward more nutritious choices without outright banning anything.
When you sign up, WeightWatchers generates a personalized daily Points budget based on your age, weight, height, sex, and activity level. You also get a weekly Points reserve for flexibility, so a dinner out or a slice of birthday cake doesn’t derail your week. The app tracks everything: you log your meals, and it subtracts from your budget automatically.
ZeroPoint Foods
One of the program’s most distinctive features is a large category of foods that carry zero Points, meaning you can eat them freely without tracking. These aren’t just leafy greens. The ZeroPoint list includes fruits, non-starchy vegetables, eggs, chicken and turkey, fish and shellfish, beans, peas, lentils, oats, tofu, tempeh, yogurt, cottage cheese, corn, popcorn, lean meats, and starchy vegetables.
WeightWatchers chose these foods because they’re packed with vitamins, minerals, protein, and fiber. The idea is that they form the foundation of a healthy eating pattern, and making them “free” removes the friction of logging every apple or hard-boiled egg. The list shifts slightly depending on which version of the program you follow. Members using the Diabetes Program, for example, get a ZeroPoint list weighted toward foods that are lower in carbohydrates and higher in fiber or protein to help manage blood sugar spikes. A Menopause Program adds avocado to the list.
What You Actually Eat
There are no required meals, no proprietary shakes, and no banned ingredients. You build your own meals from regular grocery store food and restaurants. Most members find that a typical day looks like lean protein, plenty of vegetables and fruit, whole grains, and moderate portions of higher-Point foods like cheese, bread, oils, or desserts. The program includes access to over 12,000 recipes through its app, which helps with meal planning and keeps things from getting repetitive.
This flexibility is the main selling point. You can have pizza, chocolate, or a glass of wine. It just costs Points, so you learn to balance indulgences against your daily and weekly budgets. Over time, most people naturally gravitate toward lower-Point foods simply because they let you eat more volume for fewer Points.
Does It Work for Weight Loss?
A review of 45 studies on commercial weight loss programs found that WeightWatchers members lost 2.6% more body weight after 12 months than people who received no guidance or only minimal health education. That translates to roughly 5 extra pounds for someone starting at 200 pounds. It’s a modest but clinically meaningful difference, and it held up across a large body of research.
U.S. News & World Report ranked WeightWatchers as the top pick in both its Best Weight-Loss Diets and Best Diet Programs categories for 2024, ahead of the Mediterranean diet and Noom, respectively. The program scores well because it doesn’t eliminate food groups, encourages sustainable habits, and has more published research behind it than most commercial competitors.
Activity and Lifestyle Tracking
The program goes beyond food. Your WeightWatchers app integrates with fitness trackers and logs physical activity, sleep, and an overall “Weight Health Score” that gives you a broader picture of your habits. Exercise earns you additional Points that can offset food intake, which creates an incentive to move more without making workouts feel mandatory. The app also includes fitness content and an AI body scanner for tracking physical changes over time.
Membership Plans and Pricing
WeightWatchers offers two main tiers, both requiring a 12-month commitment that auto-renews:
- Core starts at $12 per month and includes the full Points program, recipe database, macro tracking, activity and sleep integration, access to the members-only social network, and specialized tracks for diabetes, menopause, and postpartum nursing.
- Core+ starts at $22 per month and adds coaching sessions, live workshops, and enhanced support features. It’s designed for people who want more structured accountability, whether or not they’re using weight loss medication.
Both plans are app-based. The days of mandatory in-person weigh-ins are gone, though virtual coaching and community features fill that role for members who want social support.
The GLP-1 Medication Program
WeightWatchers has expanded into prescription weight loss medications through a program called Med+. Members can meet virtually with board-certified clinicians who may prescribe GLP-1 medications (the same class as Ozempic and Wegovy). The company reports that members prescribed a GLP-1 through Med+ lost an average of 7.4 pounds within their first four weeks of starting treatment. Those who paired medication with the GLP-1 Success Program lost 61% more body weight after one month than those who took medication alone.
The Med+ tier includes dosage tracking, side-effect support, expert coaching, access to registered dietitians, and an insurance support team that checks your coverage. It’s a significant expansion from the company’s food-only roots, reflecting the broader shift in weight management toward combining behavioral programs with pharmaceutical tools. Members get a dedicated care team of clinicians, fitness coaches, and dietitians.
Who It Works Best For
WeightWatchers tends to suit people who want structure without rigidity. If you’ve tried diets that cut out entire food groups and found them unsustainable, the Points system offers guardrails that still leave room for real life. The generous ZeroPoint list means you’re unlikely to feel hungry, and the weekly Points reserve builds in a buffer for social eating.
It’s less ideal for people who prefer a more prescriptive approach with specific meal plans laid out for them, or for those who find food logging tedious. The system only works if you track consistently, especially in the early weeks before you develop an intuitive sense of what foods cost. The monthly subscription also adds up over time, particularly at the higher tiers, so it helps to treat the program as a skill-building phase rather than a permanent expense.
