The Swiss Obesity Study is a prospective cohort study that follows people with overweight or obesity for up to 10 years.

The study investigates long-term changes in weight and health, the impact of modern treatment approaches, and the influence of lifestyle factors such as nutrition and physical activity. It also examines obesity-related comorbidities, quality of life, and socioeconomic aspects.

The findings aim to improve our understanding of obesity and contribute to better counseling, treatment, and long-term care for people with overweight or obesity.
