America's Best Weight Loss Clinics & Centers 2025

The list of America’s Best Weight Loss Clinics & Centers 2025 is based on three data sources:

(1) From August to September 2024, Newsweek and Statista invited thousands of medical professionals with knowledge about weight loss (e.g., bariatricians, registered bariatric nurses, general practitioners, and clinic managers) to complete an online survey. Participants were asked to name the leading weight loss clinics and centers. The professional experience of the participant was taken into account. Recommendations for their own employer were not allowed.

(2) For each recommended facility, survey participants were asked to rate four quality dimensions on a scale from 1 (“Poor”) to 10 (“Excellent”), including provision of care and patient safety, patient-centered care (education, counseling and support services), overall nurse staffing, and technical equipment. An overall quality score was assigned based on the weighted average of these ratings.

(3) Accreditation from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP), a voluntary accreditation program by the American College of Surgeons (ACS) and the American Society for Metabolic and Bariatric Surgery (ASMBS), was also considered. The accreditation reflects a center’s ability to maintain certain physical resources, human resources, and standards of practice, therefore establishing consistent standards of excellence while fostering ongoing quality improvement. However, since not all weight loss clinics and centers offer bariatric surgery and accreditation is not relevant for every facility, these clinics were evaluated based on a scoring model comprising only peer recommendations and quality dimensions.

For the evaluation, Statista applied a scoring model. Scores were calculated for each hospital in the three categories and weighted accordingly: National online survey of weight loss clinic recommendations from peers (80% of the total score), quality dimensions (15%), accreditation score (5%). Results from scoring model yielded the top 200 list.
