*Weight Health is the degree to which an individual’s weight affects their metabolic health and well-being. Weight Health is impacted by genetic, biological, hormonal, environmental, and behavioral factors unique to each individual. Weight-healthy living aims to prevent and better manage the chronic diseases and result from excess body fat including type 2 diabetes, high cholesterol, and cardiovascular disease with the ultimate goal of improving health, well-being, and quality of life.

Helping more people reach their goals

We recognize that weight management isn’t one size fits all. Our evidence-based program is the gold standard for behavioral weight management. At the same time, we understand that obesity is a complex disease with both biological and behavioral components and for many, medications are needed to address the biological drivers of obesity; medication and healthy habits make a powerful long-term obesity treatment.

We can support a journey that pairs prescription weight-loss medications, for those who are eligible, with our science-backed behavior change program and connect with clinical care provided anywhere in your provider network and/or our virtual clinic, Sequence.
