Understanding WW Points: The Science Behind Simplifying Food Choices

By Sarah Z. Wexler | Scientifically reviewed by Kelli Richardson, Ph.D., RDN

Weight Watchers first introduced Points^® in 1998, but the way Points are calculated has changed over time to stay in lockstep with the latest nutrition research. What hasn’t changed? The concept of Points: Simplifying complex information so people can make food choices faster and easier.

“When people pick up a package of food, the nutrition label gives them a lot of data: calories, saturated and total fat, cholesterol, fiber, carbs, protein, and more. It takes a lot of information and time to interpret whether that food is a nutritional choice they want to make or not," says Fernanda Almeida, R.D., senior manager of global nutrition & food data operations at Weight Watchers. “Points simplify decision-making, because we’ve already done the complex calculations and assessments behind the scenes to give members an overall health value for each food.”

Here’s how members can use Points so they stay satisfied, nourished, and energized on their weight journey.

What are Points — and how are they determined?

Points are the numbers that Weight Watchers assigns to foods to help make deciding what to eat simpler. To calculate each food’s number, Almeida says that Weight Watchers Registered Dietitians use a mathematical equation based on nutrients we want more of in a diet (fiber, protein, unsaturated fat), which help bring Points down, as well as nutrients to minimize (saturated fat, added sugars), which raise Points. In some ways, Points can be immune to trends of the moment — like the ‘90s fat-free craze, or today’s high-protein obsession — because they’re not focused on a single nutrient. “Points give members a more complete picture,” Almeida says.

Are Points the same as calories?

No. Points take calories into consideration, but they aren’t the same — because not all calories are the same, says Almeida. “300 calories from a meal of lean protein, veggies, quinoa, and olive oil is not nutritionally equal to 300 calories from soda. They’ll have different impacts on how full members feel and even their long-term health.”

That’s why Points take more factors into consideration than calories alone. Instead of falsely comparing 300 to 300 like they’re equivalent, consider that the meal would only have about 4 Points (3 Points for ½ cup cooked quinoa, 1 Point for 1 tsp of olive oil, with everything else being ZeroPoint^® foods), while the soda (25 fl ounces) would hit about 25 Points, making the disparities much more clear.

Counting Points is also not the same as counting macronutrients (carbohydrates, proteins, and fats).

Carbs in whole vegetables, fruits, beans, and grains are bundled with lots of other nutrients — including fiber, which helps members feel satisfied. On the other hand, the carbs in a chocolate chip cookie (though delicious) generally don’t come with the same nutritional perks.

Likewise, not all fats are the same. High amounts of saturated fat — found in foods such as red meat and butter — are associated with an increased risk of developing health conditions like heart disease. Meanwhile, the unsaturated fats found in avocado, seafood, nuts, and plant-based oils may help reduce disease risk.

How is a member’s Points Budget calculated?

How many Points members should eat each day is called their Daily Points Budget. It’s different for each person, based on their metabolic rate, which is calculated using age, height, weight, and sex assigned at birth. It also considers whether members are looking to lose weight or maintain it. Then the Weight Watchers team again does complex calculations to figure out how much energy members need, using equations that have been tested so calories aren't cut too much or not enough. This tailored Budget will adjust over time as members age, lose weight, or as goals change.

Then members have what’s called their Weekly Points (or Weeklies). These are additional Points members can spend each week, and they don’t kick in until Daily Points are exhausted. These Weekly Points — available in all Modes except All-In Mode — are still designed for weight loss even when used. Members can rest assured that even if they use all of their Weeklies, they should still see weight loss. Members can also add to their Weeklies Budget in a few ways:

Activity Points: Log workouts to get additional Weekly Points. Members don’t have to worry about gaining weight when using these Points because they’ll still be burning more than what’s added.

Roll-overs: This is a feature that can be turned off in the app, but defaults to being on, which means that if members don’t use all of their Daily Points, they can roll over up to four Points to their Weekly bank.

Are high-Points foods bad?

With Weight Watchers, no food is “bad” or off-limits. An item with a high Points total is just information about what’s inside, so members can make the best choice for themselves.

For example, if members love ice cream, there’s absolutely room for that in their diet with Weight Watchers, says Almeida — they may just need to keep serving sizes smaller and the rest of the day’s Points lower to fit a scoop into their Points Budget.

“We want members to enjoy eating. The idea is to be informed so members can make decisions to fit their goals, not to be joyless,” she says.

What’s the best way for members to use Points?

Members choose how and when to spend Points. They can save more of them to make room for higher-Points items at specific meals, if they wish. For example, restaurant meals tend to be higher in Points because they typically have more saturated fat and calories due to bigger portions, and diners often go for items like wine and dessert that they might not at home.

“Know yourself, prioritize what matters most to you, and plan accordingly,” says Almeida. “If members are going out for dinner, they might want to save 50-75% of their Points for that, and then have low-Point meals for breakfast and lunch.”

Focusing on building those breakfast and lunch meals with ZeroPoints foods that don’t take anything out of a member's Budget will be key to making this happen — more on those below.

Should members try to go below their Points Budget?

No, the goal is not trying to eat as few Points as possible, but to actually use all of a daily Points Budget.

“Remember, that number has been calculated specifically for what a member's body needs — trust that if followed, members will lose weight,” Almeida says. That’s because Weight Watchers’ behavior change science results in 3.5x more weight loss than standard nutritional guidance.*

Going below a Points total can lead to several issues:

Missing out on important nutrients: If members aren't eating enough, they become at risk of vitamin and mineral deficiencies, which can have negative short-term and long-term health impacts. Not eating enough also likely means not getting the protein needed, which is extra important during weight loss to preserve muscle mass.

Slowing metabolism: “Our bodies are smart and adapt. When someone goes too far into a calorie deficit, the body thinks it's starving and will slow metabolism down and get very efficient. This means it will use fewer calories at baseline, which is the opposite of what we want,” Almeida says.

Getting bored: Sure, raw veggies are healthy, but eaten solo, they get boring — which means it’s not a sustainable way to eat long-term. “Adding olive oil for cooking vegetables or a dip for crudites like ranch does add some Points, but it also brings some joy and excitement, which helps members stick with it in the long run,” Almeida says.

What if members are still hungry?

Enter ZeroPoint foods — which are most foods that show up as having no Points. We never want members to feel hungry on their Weight Watchers journey, so they can always turn to these nutritional powerhouses. Packed with nutrients, vitamins, and minerals, these foods form the foundation of healthy eating.

Members also don’t have to diligently weigh, measure, or track them, no matter how often they reach for them since they don’t impact their budget. That said, if members are paying attention to macros or other nutrients in addition to Points, they should consider tracking ZeroPoint foods normally. Otherwise, their macronutrient view (especially when paying attention to protein or fiber) will be significantly off.

ZeroPoint foods include beans, peas, lentils, fish, shellfish, fruits, corn, popcorn, lean meats, vegetables, oats, tofu, Greek yogurt, and cottage cheese, though the list will vary from this slightly for those living with diabetes or who are on our Menopause Program. 

The bottom line

Weight Watchers uses Points to make decision-making around food faster and simpler. The Points for every food is determined through a mathematical equation based on nutrients members want more of in their diet (fiber, protein, unsaturated fat) and things they want to minimize (saturated fat, added sugars). A member's personal Points budget has been calculated specifically for what their body needs — trust that if followed, it can help members lose weight. And if members use all of their Points, they can always rely on ZeroPoints foods so they never have to feel hungry.
