Weight Watchers revamped its program having a plan that shifts the focus from weight loss because the ultimate goal.

The new program, called “Beyond the Scale” is in response to both changing science about nutrition and consumer sentiments, says Gary Foster, Weight Watchers’ Chief Scientific Officer. “The approach we take to think about it is the fact that we once had a very narrow focus on weight, and now weight is one of things we concentrate on but it is not the only thing,” he says. “The consumer sentiment is, ‘I still want to lose weight but I’m thinking about in a more holistic way.”

The rollout from the new program had some bumps, with some customers?taking to Twitter to complain that the app, which is popular with Weight Watchers members, wasn’t working. Some users also reported that their daily “points”-a figure Dieters allots users that, if followed, is made to assist with weight loss-changed without greatly public explanation. Indeed, what exactly for several foods have changed, with a brand new points program called SmartPoints.

TIME asked Foster to explain the changes-and the reasoning behind them.

The brand has always taken complicated nutrition information and used an algorithm to turn that food into one simple number. Previously, the algorithm was based in part on broad categories including calories, protein, fat and carbohydrates. Now, Dieters is applying a new formula that appears at the kind of fat inside a given food, for example, with saturated fat pointed more heavily. Lean protein, too, has fewer points that other meats. And while the old formula lumped sugar in with carbohydrates, they’re now calculated separately.

Roughly 40 to 50% from the foods in the system remain relatively the same points-wise, as the rest goes up or down. Fruits and vegetables get zero points.

Dieters customers could also notice that their own personal daily and weekly allotments have changed. That is because of another formula tweak based on a new method to calculate a person’s resting metabolic rate. “The old formula was more based on folks that weren’t overweight, and the new formula is more accurate for those who are overweight,” says Foster.

Members may notice changes for their weekly points, that is a cache of extra points that can be used if an individual thinks they will exceed their daily points. Previously, everyone got 49 extra points per week, regardless of their resting metabolism. Now, the weekly allotment is specific to individuals’ metabolic rates, and ranges from 14 to 42 points, says Foster.

“In yesteryear, we framed exercise as something which was nice to complete. It had not been necessarily a core a part of our program,” says Foster. Under the old system, every exercise point translated into extra food points. Now, users have both a consumption goal, along with a physical activity goal. (If members desire to use their activity points as food points, they can go into the program and change their settings.)

Weight Watchers can also be encouraging members to do non-food related stuff that make them feel great. This will be a greater facet of Weight Watcher meetings.
