Noom is a digital weight-loss program and app that provides users with a personalized diet plan, instant access to AI and human-led coaching, and a supportive community. The Noom diet is based on a few key principles: calorie counting, a color-coded food system, clean eating, and behaviour change. Noom encourages users to log their food, which is then categorized into green, yellow, and red based on nutrient density and calorie content. It promotes whole, unprocessed, and low-calorie foods, such as fresh vegetables and lean proteins, and discourages high-calorie, low-nutrient options. Noom also focuses on behaviour change, aiming to help users develop healthier habits and a positive relationship with food. While Noom has been praised for its comprehensive approach to weight loss, it has also faced controversy due to its potential to trigger disordered eating.

What You'll Learn

Clean eating
Noom's color-coded food system helps users make informed choices and easily identify nutrient-dense foods, making clean eating simpler. Green foods are the least calorie-dense and packed with essential nutrients. These typically form the foundation of a clean eating plan. Yellow foods are still nutritious but are more calorie-dense, so they should be eaten in moderation. Orange foods are the most calorie-dense and are generally lower in nutrients, so they should be eaten sparingly.
Noom's approach to clean eating is to help users create a plan that fits their lifestyle and empowers them to thrive. It is not about strict rules or complicated meal plans but about nourishing the body with wholesome, minimally processed foods. Noom's color-coded system acts as a nutritional traffic light, guiding users towards healthier food choices.
Noom's clean eating plan is about being more aware of the foods you choose to eat and aiming for quality. It is not a restrictive diet, and no food is forbidden. It is about making gradual changes, meal prepping, and carefully considering food choices.

Calorie counting
Noom uses a colour-coded system to categorise foods based on their calorie content and nutritional makeup. Green-labelled foods contain the most nutrients and the fewest calories, while red-labelled foods have more calories and fewer nutrients. Yellow-labelled foods fall in between. This system guides users to choose foods with high water content and are the most filling for the fewest calories. For example, users are encouraged to select fresh apples instead of apple pie and spinach salad instead of creamed spinach.
Noom also provides dynamic calorie goals, which are personalised daily calorie ranges based on factors such as age, gender, weight loss goals, and daily activity levels. The app recommends eating within this "Weight Loss Zone" to ensure safe and effective weight loss. Eating at the lower end of the zone can lead to greater weight loss, while eating at the higher end results in more moderate weight loss.
In addition to food choices, Noom also emphasises the impact of drinks on calorie intake. Sugary drinks, coffee-based beverages, and alcoholic drinks can add hundreds of calories to the diet, so Noom suggests eliminating or substituting them with lower-calorie options.
While calorie counting is a central aspect of Noom, it also incorporates behavioural components to help users develop healthy habits for lifelong weight management. The app provides ongoing support from health coaches, who offer personalised feedback and guidance based on users' food logs and weight loss goals.

Logging meals
The Noom diet is based on a colour-coded system, with foods labelled as green, yellow, or red, depending on their nutritional value and calorie content. Green-labelled foods are nutrient-dense and low in calories, while red-labelled foods are less nutritious and higher in calories. The goal is to shift towards consuming more green-labelled foods, such as fresh vegetables and lean proteins, which are low in calories and filling.
The Noom app provides ongoing support and resources, including access to a health coach, community connections, and a range of recipes. It also offers a diabetes prevention program that has been recognised by the Centers for Disease Control and Prevention (CDC) for its effectiveness. However, it is important to note that the Noom diet may not be suitable for individuals with eating disorders or a history of disordered eating.

Weight loss
Noom is a digital weight loss program that offers a personalized diet plan and access to an online health coach. The program is available through a phone app of the same name. Noom claims to help people reach their weight goals and achieve and maintain a moderate weight.
Noom is based on a holistic approach to weight loss, focusing on long-term weight management through nutritious eating and exercise habits. The app encourages users to eat low-calorie dense foods, such as fresh vegetables and lean proteins, and to limit the consumption of some "red label" foods that are otherwise considered healthy. Noom uses a color-coded system to help users identify nutrient-dense foods, with green-labeled foods containing the most nutrients and the least amount of calories, and red-labeled foods containing more calories and fewer nutrients. The app also provides a food database of more than 150,000 items to help users track their daily caloric intake.
The Noom program combines technology, human coaching, and psychology to help individuals build healthier eating habits. The app offers ongoing support, daily lessons, and a community connection through Noom Circles and Noom Vibe. It also provides habit tracking and on-demand workouts, as well as generic workout guides and daily step goals.
In addition to the standard Noom program, there is also Noom Med, which offers prescription weight loss medications to qualified patients. Noom Med provides access to a clinical care team that evaluates patients and makes recommendations for weight loss medications.
While Noom has been shown to be effective for weight loss, it has also been controversial. Some people believe that its focus on calorie-restricted diets, food tracking, and regular weighing may trigger disordered eating in some users. As a result, Noom may not be suitable for individuals living with or recovering from an eating disorder.

Health coaching
Noom's health coaching is based on a psychology-based approach that focuses on long-term behaviour changes rather than short-term restrictive diets. The program targets habits and mindsets, offering daily lessons and a colour-coded food system. The colour-coded system groups foods into three categories: green, yellow, and red, based on their calorie content and nutritional makeup. Green-labelled foods contain the most nutrients and fewest calories, while red-labelled foods have more calories and fewer nutrients. This system helps users make healthier food choices and understand their calorie needs.
Noom also provides ongoing support through its community features, such as Noom Circles and Noom Vibe, where users can connect with others on similar journeys. The program encourages self-monitoring and regular logging of meals, snacks, and daily weights through its app, which then provides feedback and guidance based on the user's food choices and activity levels.
Additionally, Noom offers a diabetes prevention program recognised by the CDC and provides access to weight loss medications for eligible individuals. It is important to note that Noom may not be suitable for everyone, especially those with eating disorders or a history of disordered eating, due to its focus on calorie restriction and regular weighing.
Overall, Noom's health coaching combines technology, human coaching, and psychology to help individuals build healthier eating habits and achieve sustainable weight loss.
