The Noom app has fast become one of the most popular choices on both iOS and Android platforms, with over 10 million installations and hundreds of thousands predominantly positive reviews on the Play Store alone so far.

It is designed to change your behavior towards food and create healthier habits; the majority of reviewers highlight that they have lost weight since starting the Noom diet.

What I was particularly interested in is what types of food they recommend and how they tailor the advice to help users lose weight in a sustainable way.

So, I went and spent a few days reading the reviews and chatting with users in Facebook groups and forums.

Here’s what I found...

Calorie Tracking Made Easy

When it comes to achieving a healthy weight goal it’s all about the calories in foods you take in, and the energy burn [1].

Essentially, if you take in fewer calories than you use throughout the day, then you will lose weight in the long term.

The problem is that under most diet guidelines you end up starving yourself and just feeling miserable. As a result, so many people just give up and move onto the next shiny advertisement that promises miracle results.

Noom diet is quite different in that it aims to monitor your caloric values throughout the day and display them so you can make sure you take in less than you use. Once fully set up, you can see your calories in minus your exercise and activity all in one place.

But, how do they get you to focus on the food you eat?

Noom's Food Database Contains 3.7 Million Foods

According to the latest information on Noom’s website, their food database has grown to 3.7 million different foods.

Most people will probably find it difficult to name a thousand different edible products, so it’s quite likely that whatever you’re eating, you’ll find it in the app.

For each snack or meal during the day, you can simply use the search function, and it will even bring up branded products.

The database has information on all the nutrients and calories and once you add the amount you consumed, it will calculate the calorie amount based on that.

Because most people have their phone with them at all times, it’s a very easy way to immediately add everything you eat in a matter of seconds.

You can then check your daily Noom diet progress to see if you can afford to eat that sneaky muffin on your coffee break.

As long as you are honest with everything you add and you have a daily calorie deficit, then you will be steadily getting closer to your weight-loss goals.

Noom Diet Food Color List

Noom is all about getting people to good foods and healthy eating habits.

Rather than imposing a very strict diet plan where all sorts of foods are completely off limits, the company aims to simply replace high-calorie foods for lower ones.

To help you make better choices for your diet, Noom assigns a color-coding list based on a calorie scale effective for losing weight.

This is available in the Healthy Weight program (more on this below), and many users say it really helps you to come up with better meal plans and recipes.

1. Green Foods List

This is the list you want to focus most of your attention on. Green foods have the least calorie density or contain a lot of other very healthy nutrients that is very good for healthy eating and for your diet.

As you would expect, green foods are predominantly green vegetables, whole grains, some fruit, and berries as well as a few dairy products.

These are ideal foods to focus on and plan for throughout the day to fill you up and avoid the dreaded hunger pains while losing weight. Here are some examples of green foods:

  • Lettuce
  • Onion
  • Green beans
  • Spinach
  • Broccoli
  • Brussel sprouts
  • Carrots
  • Tomatoes
  • Oranges
  • Blueberries
  • Cherries
  • Watermelon
  • Strawberries
  • Apples
  • Bananas
  • Almond milk
  • Low -fat cheese
  • Egg whites
  • Oatmeal
  • Brown Rice
  • Whole grain bread
  • Sweet potatoes
  • Peas
  • Tofu

2. Yellow Foods List

This category is a bit more calorie-dense and you should only have a moderate amount of these in your diet plan.

These yellow foods are slightly less beneficial from a nutritional perspective compared to green foods, but they are filling and more nutrient-dense than red foods.

What’s great about the color coding is that you can search for a group of foods and then pick green instead of yellow foods for healthy eating.

You’d be surprised how many substitutions you could make this way.

Here are some examples of yellow foods:

  • Lean meat
  • Fresh tuna
  • Turkey breast
  • Grilled skinless
  • Low-fat milk
  • Low-fat cheese
  • Avocados
  • Beans
  • Olives
  • Hummus
  • Couscous
  • Quinoa
  • Tempeh
  • Guacamole

3. Red Foods List

These are the foods you want to avoid or at least keep the portion size as small as possible. Red foods are more calorie dense or have very little nutritional value.

In many cases, these red foods are keeping people from healthy eating and achieve goals to lose weight.

Here are some examples of red foods:

  • Ham
  • Fried meat
  • Bacon
  • Sausage
  • Salami
  • Mayonnaise
  • Pizza
  • Fries
  • Chocolate
  • Peanut Butter
  • Fruit Juice
  • Hamburgers
  • Chips
  • Sugar
  • White flour
  • Wine (yes, unfortunately)

Noom Programs

The way Noom is designed is you have two main programs available and it’s important that you understand what they are before you make a choice.

1. Healthy Weight Program - which is what the majority of users work with for losing weight.

This is a weight loss program that aims to get you to keep a journal of what foods you eat throughout the day.

This is also where the above-mentioned color coding is used to help you identify foods that are less calorie-dense and more nutritional for your diet plan.

And, if you also sync up your fitness trackers, then you’ll get a full picture of your calorie surplus or deficit.

2. Diabetes Prevention Program - and this is where the app will help you avoid the high-carbohydrate types of foods. By helping you reduce your carb intake, you will find it easier to lower and balance your blood sugar levels.

A lot of diabetic users have commented that it does help with their daily carb tracking.

Unlike other buzz-worthing meal plans, it's not an elimination diet which means every food group is on the menu. Unlike other calorie tracking apps, the focus on making behavioral changes surrounding dieting and weight loss.
