Weight Management
Body mass index (BMI) is widely used to assess health, but it has significant flaws for evaluating individuals. Originally developed for population studies, BMI fails to differentiate between muscle, bone, and fat, potentially misclassifying fit people as overweight. Experts recommend alternative metrics that better account for fat distribution and overall health risks.

A novel weight management initiative called PATHWEIGH, developed by endocrinologist Leigh Perreault, has successfully stopped population-level weight gain in primary care settings across Colorado. Tested in a large-scale trial involving over 274,000 patients, the program increased access to obesity treatments and is now attracting interest from health systems nationwide. Published results show a 0.58 kg reduction in average weight gain over 18 months, marking a significant public health advancement.
