Losing weight often leads individuals to explore the numerous weight loss apps available today. These apps offer a range of features, from recipe inspiration and motivational support to workout tips and structured diet plans. Among these apps, Noom has been a prominent player for over a decade, providing users with recipe ideas, diet structure, and various tools to support their weight loss journey. While Noom has garnered positive reviews, some users have expressed confusion regarding its food lists and categories.
Understanding the Noom Diet
The Noom diet is an approach delivered through an app that combines food and calorie tracking with behavior change strategies. Like most diets, it helps users lose weight by creating a caloric deficit. However, Noom distinguishes itself by emphasizing the mental aspects of weight loss, offering regular mindset strategies to help users stay on track.
Before committing to Noom, it's crucial to assess whether its food tracking method aligns with your individual needs and lifestyle. Every person and body is unique, so understanding the specifics of the Noom diet, including its food lists and recipes, is essential for making informed decisions about your dietary choices.
Expert Opinions on Noom
Several experts in the field of nutrition have shared their insights on the Noom diet:
- Charlotte Martin, MS, RDN: "Noom is an approach to dieting delivered via an app that combines food and calorie tracking with behavior change strategies. Like most diets, it helps consumers lose weight by creating a caloric deficit. Unlike most diets, there’s an emphasis on the mental aspects of weight loss, and the app provides regular mindset strategies for helping consumers stay the course.”
- Jonathan Valdez, RDN: Noom uses an orange, green, and yellow color system, instead of categorizing foods purely as ‘good’ or ‘bad,’ to help the user gauge what is nutrient-dense and what is not.
- Kimberly Gomer, RD: Noom will calculate a daily calorie goal and food suggestions based on how much weight you want to lose.
- Allison Koch, MS, RDN: “The app has a psychological component and aims to create sustainable lifelong changes by tapping into the user's psychological experience. However, my concerns are the very low calorie levels it sets for users without fully understanding the user’s life experience, body composition, or fitness level.”
How Noom Works
The Noom app functions as an all-in-one trainer, nutritionist, and health coach. While the app itself is free and offers a one-week trial, membership costs can reach up to $70 per month, depending on your goals and desired weight loss.

Upon downloading the app, Noom requests access to your iPhone's Health app to log your exercise and food intake. The app utilizes a database of foods and employs a color-coded system-orange, green, and yellow-to categorize foods based on their nutrient density, instead of simply labeling them as 'good' or 'bad'.
The Noom Color-Coded Food System
Noom's color-coded system is a central component of the diet, providing a visual guide to help users make informed food choices:
- Green: These foods are the least calorically dense and/or most nutrient-dense. About 30 percent of your intake should come from green foods.
- Yellow: These foods fall in the middle range for caloric density and nutrient density. About 45 percent of your intake should come from yellow foods.
- Orange: These foods are the most calorically dense and/or least nutrient-dense. About 25 percent of your intake should come from orange foods.
It's important to note that Noom's color system serves as a portion guide rather than a strict "good" versus "bad" food classification. "Orange" foods may raise a red flag for foods that contain a lot of calories without filling you up.

Potential Downsides of Noom
While Noom offers several benefits, it's important to consider potential drawbacks:
- Food Guilt: The color system may inadvertently lead to unnecessary food guilt, with some individuals associating green foods as "good" and orange foods as "bad," which isn't necessarily accurate.
- Low Calorie Levels: Concerns exist regarding the very low calorie levels that Noom sets for users without fully understanding their life experience, body composition, or fitness level.
- Lack of Macronutrient Tracking: Noom primarily tracks calories and doesn’t provide information on macronutrient breakdown, which is crucial for understanding a balanced diet.
- Tedious Food Logging: Noom expects users to manually log all their food each day, which can be extremely tedious.
Who Should Avoid Noom?
Noom may not be suitable for everyone, particularly:
- Individuals with a History of Disordered Eating: The diet may trigger unhealthy behaviors and worsen their condition.
- Those Distressed by Daily Weigh-Ins: The app encourages daily weighing, which can be distressing for some individuals.
- Individuals with Certain Health Conditions: Those with conditions such as irritable bowel syndrome, allergies, food intolerances, or other medical conditions requiring specialized care should consult their doctor before using Noom.
Potential Benefits of Noom
Despite its shortcomings, Noom can offer significant benefits, especially for individuals seeking to:
- Create a Caloric Deficit: Noom effectively helps users create a caloric deficit, which is fundamental to weight loss.
- Change Habits: The app provides coaching support and social support groups, encouraging positive reinforcement and accountability.
- Learn About Nutrient Density: The color system can be a useful tool to teach and guide users through making food choices based on nutrient density while allowing flexibility without restricting specific foods.
Additional Considerations for Weight Loss
Beyond the Noom diet, here are some general tips and considerations for weight loss:
- Focus on Natural Weight-Loss Foods: Prioritize foods that are low in calories but provide energy and keep you full.
- Balance Macronutrients: Ensure your diet includes a variety of macronutrients (protein, carbs, and fats) and micronutrients.
- Incorporate Healthy Fats: Unsaturated fats are an essential part of a healthy diet and can help with weight loss because they’re very satiating.
- Prioritize Protein: Protein is important for building and maintaining your muscle mass, so the best foods for weight loss and muscle tone have lots of protein.
- Choose Carbohydrates Wisely: Carbohydrates give your body energy, which will help you be more active.
- Pay Attention to Water Content: The higher a food’s water content, the more volume it will have per calorie.
- Be Mindful of Portion Sizes: Even with healthy foods, controlling portion sizes is crucial for weight loss.
