Noom Diet Plan: Does It Work?

Noom is a weight loss app that helps users make behavioural changes for a healthier lifestyle. It is promoted as building self-awareness, accountability and habits that can lead to healthy weight loss and maintenance. Noom uses an algorithm to estimate your daily calorie needs based on your sex, age, height, weight, and answers to a series of lifestyle questions. It then provides an ideal calorie range, known as the “weight loss zone”. Noom is based on tweaking your food choices rather than restricting entire food groups, so you may have a better chance of sticking to it over time.

Noom is a subscription health app that combines meal and exercise tracking with virtual coaching and education

Noom is promoted as building self-awareness, accountability and habits that can lead to healthy weight loss and maintenance. It does this by encouraging you to make small tweaks to your food choices, rather than restricting entire food groups. This approach may make it easier to stick to the plan over time. For example, Noom suggests choosing "green foods" often, and eating those in the yellow and orange categories less often. You can use the Noom app to track and research the food you eat to determine which category it's in.

Noom also includes virtual coaching and education to help you make behavioural changes for a healthier lifestyle. However, the need to track your food could be difficult or triggering for some people.
