This diet type categorizes foods by their calorie density using a color system: green (low-density), yellow (medium-density), and red (high-density).
The main goal of the Noom diet is to consume more green foods, moderate amounts of yellow foods, and fewer red foods.
- Psychology-based Curriculum: Noom emphasizes the psychological aspects of weight loss.
Food Color System:
- Green Foods: These are foods with the lowest calorie density and highest nutrient content, such as fruits, vegetables, and whole grains.
- Yellow Foods: These are foods that are more calorie-dense but can still be part of a healthy diet in moderation, like lean proteins, dairy, and legumes.
- Red Foods: These have the highest calorie density and are foods that Noom suggests you should limit.
This includes things like desserts, fried foods, and processed meats. Importantly, Noom doesn’t label these foods as “bad”; the idea is to consume them less frequently or in smaller quantities.
