Noom is a psychology-based weight management and health app that combines behavioral science with personalized coaching to help users build sustainable healthy habits. Founded in 2008 by Saeju Jeong and Artem Petakov, Noom uses a color-coded food logging system that categorizes foods into green, yellow, and orange based on caloric density. The app provides daily educational articles, quizzes, and lessons about nutrition psychology and behavior change. Users are assigned a personal coach and placed in small group communities for accountability and support. Noom tracks weight, meals, exercise, and water intake, offering insights into patterns and triggers. The app has been used by over 50 million people and has been the subject of clinical studies demonstrating its effectiveness.
