A new definition of obesity that includes body measurements beyond BMI just changed everything. In a study of 300,000 adults, obesity rates jumped 60% when waist and body fat distribution were included. This “anthropometric-only obesity” group—people with normal BMI but high fat distribution—still showed higher risks of diabetes, heart disease, and mortality. This could reshape how we diagnose, treat, and even define obesity in medicine and policy. https://jamanetwork.com/journals/jamanetworkope
