Staying Power: How Personalized Modes Drive Weight Health Engagement

The most effective weight health programs have something in common: people stay engaged in them. Not just through the enrollment window or the first burst of motivation, but through the plateaus, the busy seasons, and the changes in routine like vacations and holidays that are inevitable over the long arc of meaningful behavior change.

Sustained engagement pays off in better results for members—and the employers and health plans supporting better weight health. High engagement in health and wellness programs delivers a 25-35% reduction in claims, which is 3-4X better than low engagement programs.¹ The difference between high and low engagement often comes down to how well the program adapts to each member’s personal needs and goals.



Weight Watchers has never taken a one-program-fits-all approach, and today’s solutions take personalized support to the next level. Tailored support, AI-powered tools, and the indispensable WW app provide digital feedback and coaching, individually calibrated motivation, and behavior-triggered nudges.

One example of personalized experiences that drives engagement, and in turn, better outcomes? Customizable Modes that enable members to adjust the level and type of support they receive based on their goals, circumstances, and where they are in their weight health journey.

Four modes, one goal: keeping members engaged  

Modes give members a way to shape their program experience around their life and their weight health goals—not the other way around. Rather than a fixed track, Modes provide a science-backed path that fits, along with the flexibility for members to adjust their mode as their progress unfolds and needs change.

Lose Mode is the default for members actively working toward a weight-loss goal. The focus is on creating healthy habits, including nutrition and activity, that are sustainable in real life.

All-In Mode is designed for members who have the mental and physical bandwidth to intensify their weight-loss effort. Building on the proven tools in the Lose Mode, All-In adds increased focus on movement with a minimum activity target of 150 minutes of physical activity each week. It also unlocks exclusive access to Weight Watchers’ Weight Health Score, a 0-100 snapshot score of a member’s holistic weight health, across nutrition, activity, weight tracking, and sleep.

Maintain Mode recognizes that reaching a weight-loss goal is a milestone, but it's not the finish line. It’s designed to support members seeking to stay at their current weight, stay accountable, and stick with healthy habits for life. A meta-analysis of eight long-term weight-loss maintenance studies found that half resulted in weight regain²—and research shows that weight cycling can increase the risk of various diseases, even more than continuous obesity.

Maintain Mode keeps members engaged after they've hit their weight-loss goals, providing the consistent support that long-term weight management requires while avoiding the high-cost regain cycle that can drive healthcare spending.

Vacation Mode supports members who are traveling or taking a planned break from their routine. Rather than stepping away from the program entirely, Vacation Mode allows members to step back temporarily — staying connected to their health goals and protecting the progress they've worked hard to build.

The personalization payoff

For employers and health plans, personalized experiences like Modes create fewer off-ramps for employees. Members in active weight loss, pushing for faster results, and working to maintain their progress all have reasons to stay engaged. That continuity, across a diverse workforce and over the full weight health journey, produces the sustainable outcomes that boost population health and reduce healthcare costs.
