A behaviour-change program
Noom review
By Theo Marchetti and Hannah Whitlock · Published October 22, 2026 · Updated October 22, 2026
Noom is a paid weight-loss program built around psychology. It combines daily lessons, food logging with a colour system and coaching. It is a different kind of product from a calorie tracker, and it is listed under "also considered" in our 2027 ranking.

What it does well
- Daily lessons based on behaviour-change principles
- A simple colour system that teaches calorie density
- Coaching support as part of the program
- Useful for people who want to understand their habits, not just count
Worth knowing
- A paid program rather than a free tracker
- Less flexible as a pure calorie and nutrient log
What it is
Noom is best understood as a course with a tracker attached. Each day brings short lessons about habits, hunger, emotions and environment, drawing on ideas from cognitive behavioural approaches. Alongside the lessons you log food against a calorie budget and get support from coaches. The aim is to change how you think about eating, not only to count it.
The colour system
Noom sorts foods into green, yellow and orange, mainly by calorie density. Green foods (most vegetables and fruit, for example) give you a lot of food for few calories; orange foods (oils, nuts, sweets, many snacks) pack many calories into small amounts. No food is banned. The system is a simple way to learn the idea behind calorie density, and many people find it easier than reading numbers.
Logging
Food is logged by search or barcode against a calorie budget, with each entry tagged by colour. It works well for following the program, but people who want detailed nutrients or very fast logging for every meal will find dedicated trackers more flexible.
Price
Noom is a subscription program and its price depends on the plan length and offers available at the time. Check Noom’s own site for current pricing and the terms of any trial before signing up, including how to cancel.
Who it suits
- People who have counted calories before and want to work on the habits behind eating.
- People who like structured daily lessons.
- People who value coaching support.
Who should look elsewhere
People who only want to count calories and nutrients, and anyone who prefers a free plan. A tracker and our guides cover much of the practical ground at no cost.
How it compares
Noom is not a direct competitor to the apps in our ranking. If you want tracking with a coach you can message, PlateLens includes an AI coach with 5 free messages a day.
Verdict
Noom is a good fit for people who want a structured program about habits and psychology and are happy to pay for it. If you want a flexible tracker, with a free plan and an AI coach, PlateLens is our 2027 pick.
Questions readers ask
Is Noom a calorie counter?
Noom includes food logging and a calorie budget, but it is designed as a behaviour-change program, with daily lessons and coaching. People who only want to count calories usually choose a dedicated tracker.
What do Noom's colours mean?
Noom groups foods into green, yellow and orange based mainly on calorie density. Green foods, such as vegetables and fruit, give you a lot of food for few calories; orange foods, such as oils, nuts and sweets, are dense and best eaten in measured amounts.
