Why do two people with the same BMI respond so differently to the same weight-loss treatment? Dr. Andres Acosta explains how four obesity phenotypes—hungry brain, hungry gut, emotional eating, and slow burn—can reveal important differences in appetite, satiety, energy expenditure, and eating behavior. He discusses how identifying these phenotypes may help clinicians better match patients with targeted dietary strategies, behavioral interventions, exercise, and medications, including GLP-1–based therapies. The conversation highlights emerging research showing that a precision approach to obesity could improve weight-loss outcomes while moving treatment beyond a one-size-fits-all model.
