Noom Diet In A Nutshell

At this point – Noom makes the top-rated weight loss program.

It's not me saying this – it's the huge per cent of satisfied users it has:

  • over 80% 5-star reviews
  • effective in most cases of weight loss
  • very few negative opinions/complaints

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Now, what makes Noom different?

Is it the fact that it's designed as an app? Not really…

It's probably the fact that it doesn't only help you lose weight – but it teaches you how to keep it there.

That's something a lot of weight loss programs lack.

They all focus on weight loss – but most people gain all the weight back in 3 months after giving them up.

On the other hand, Noom teaches you how to avoid that:

  1. Reduces your weight gain triggers.
  2. Changes your behavioral response and eating habits.
  3. Improves your weight loss process.

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

But how exactly does it do that?

Well, it's based on a unique food color strategy:

  1. All foods are divided in 3 groups (green, yellow, red).
  2. The app classifies each food you eat in a group.
  3. You have a daily budget for each group.
  4. You also get a personal coach and a support team.
  5. Besides, you have to follow some short lessons everyday.
  6. They are meant to change your response to foods and diet.

Honestly, there are thousands of people who swear by Noom.

Like I said – no weight loss program has such a high amount of praises.

Given its unique strategy and weight loss plan, I'm not surprised it works so well.

So if you afford giving it a try, I totally recommend Noom.

Even if you can't afford the monthly membership – just go for the $1 14 days trial.

At least you get to see that it's really worth it.

One year from now, you will enjoy your ideal weight without worrying about gaining it back.




#1 – What Is Noom?

As you can tell by now, Noom is a weight loss program that has been very popular lately:

  1. Based on an original app.
  2. Sets you a personalized calories budget everyday.
  3. Changes your eating habits through behavioral therapy.
  4. Gives you some customized lessons every day.
  5. Teaches how you to keep your weight (without using Noom anymore).

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Now, all these features sound great. 

But what if they didn't convince you?

In fact, what makes Noom better than all the other weight loss programs out there?

I would say it's its long-term goal.

That's because Noom is focused on helping you lose weight AND maintaining it there:

  • most programs are only designed on fast weight loss
  • however, their results are usually short-term
  • in order to keep your weight constant, they recommend a continuous membership

On the other hand, Noom comes with a specific time frame.

In other words – you know from the start for how long you need to use this program.

Once you get to the end, they even recommend cancelling your membership.

That's an advantage over most weight loss programs:

  • they all advise you to stay with them forever
  • some even prevent you from cancelling your membership (through unfair practices)

So Noom's goal is to teach you how to keep your weight on the lower side, once you reached your goal.

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

There are several features you can find in the app:

  1. Customized weight loss plan
  2. Food (calories) counting program
  3. Weight, exercise and meals trackers
  4. Coaching group and goal specialist (coach)

Since so many people have lost weight with Noom, it's obvious that it works.

And given its strategy, I consider it one of the best weight loss programs out there.

It's so easy to lose weight with it that you absolutely have to try it out!



#2 – How It Works & History

In case you need some general facts about Noom, here they are:

  • its mechanism of action
  • who it works best for 
  • its history
1. How It Works

What makes Noom special is that it's customized for your own weight loss goals.

For this reason – it works through a quiz you need to take before starting out.

Most of this quiz's questions are related to:

  • events that could have made you gain weight
  • period of time since you have had this weight
  • reasons why you want to lose some pounds
  • your daily habits
  • climate you live in

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Now, the quiz is a bit different from person to person.

It's created to depend on your answers to each question.

In this way – it can ask you something totally different than another Noom user.

That's definitely a very personalized part.

Based on your quiz, the app created a customized weight loss plan for you:

  1. You're told right off how much time you need to get to that weight.
  2. That period is very realistic (no exaggerations).
  3. You start with a daily calorie plan.
  4. Your foods are divided in red, yellow and green (based on their calories).
  5. The app tells you where you stand (based on these criteria).

In other words – you have to log in your daily meals.

The app will automatically tell you which of those foods are green, yellow or red.

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Going on, you receive some daily personalized lessons on the app.

Their goal is to teach you how to give up the causes that made you gain weight.

In this way – once you lose your desired weight, you're able to keep it there.

You can even choose the time you want to spend on a lesson:

  • 1-4 minutes
  • 5-8 minutes
  • 9-12 minutes everyday

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Besides, Noom even encourages you to spend only a few minutes per day on the app.

Other than the daily lessons, you also have access to:

  1. Educational articles
  2. Weight loss tips
  3. Physical activities 

Obviously – all of them are related to losing weight correctly (and maintaining it).

Besides, you also receive access to a personal coach and a support group.

In case you ever need motivation, they are all there for you:

  • many previous users claim these groups are great
  • coaches are also very helpful and understanding

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

So many previous users of Noom claim a big part of their results are because of these supportive people.

Honestly, the app itself is brilliant and very easy to use.

I'm pretty sure it's going to help you lose your desired weight (and keep it).

2. History

Noom was probably the first weight loss app from the market.

It was launched in 2008 and its popularity increased almost instantly:

  1. Founded by Saeju Jeong and Artem Petakov.
  2. Their motivation was the poor American weight loss system.
  3. According to them, there's a focus on the “sick” care instead of the “health” care.

That's exactly what Noom was trying to fix.

The app was designed to tell you HOW to improve your health, weight and goals.

It also helps you understand WHY these improvements will change your life for good.

Honestly, the brand has a great reputation:

  • thousands of previous users that swear by it
  • lots of customer reviews on its social media accounts
  • no major complaints

In other words – you can buy from this brand without any worries of being scammed.

Their excellent user feedback is the best proof, to be honest.




#3 – Weight Loss Plans (9 out of 10)

One of the best things about Noom is that it offers 2 different programs:

  • weight loss
  • diabetes prevention

Now, its weight loss plan is very personalized.

And when I say “personalized”, I really mean that.

Most weight loss programs claim to offer “personalized” plans – and they actually only have 2 or 3 different ones.

But Noom is totally different here.

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

So 2 users signing up at the same time would have some totally different plans.

Honestly, that's a major advantage it comes with.

What about its diabetes prevention plan?

Well, it's a unique approach Noom offers – and guess what? It's really effective.

So let's take a closer look at each of them.

1. Weight Loss Plan

This is definitely Noom's most popular version and the reason why most users try it out.

As I said – it's designed to change your behaviour and habits in the long run.

The goal isn't only to lose weight – but also to maintain it:

  • creates some unique daily lessons for you
  • matches you with a personal coach and a support group
  • offers you some individual ways to reduce your weight

Other than that, Noom's classic feature are its food colors:

  1. Green for low-calorie foods
  2. Yellow for average foods
  3. Red for foods with a high calorie count

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Depending on your quiz, Noom will recommend you a certain amount of calories/day.

In most cases, here's how you should divide your foods:

  • 30% green foods
  • 45% yellow foods
  • 25% red foods

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Honestly, this strategy is very easy to follow.

Besides, the app tells you exactly the color and the calorie number of your foods.

So this plan is extremely simple and convenient.

2. Diabetes Prevention Plan

This plan is excellent if you have a family of diabetes or if you're at risk (for any other reason).

Shortly – its goal is to help you lose weight.

According to Noom, losing 5% of weight reduces your diabetes risk by 58%.

Now, here's how this plan works:

  1. You're assigned to a special coach.
  2. These coaches are specialized on diabetes (so they are different from the other program).
  3. You receive a personal coach that will stay with your throughout your journey.
  4. Your coach will work with you on nutrition, behavioural triggers, etc.

Shortly – Noom's diabetes prevention plan is divided in several phases:

  • First stage – Learning
  • Second stage – Practice
  • Third stage – Advanced Learning
  • Fourth stage – Mastery

Obviously, you also have access to Noom app and its features from weight loss plan.

But all in all, lost of people claim they reduced their diabetes risk with this program.

It's very easy to follow and it's also very effective.


Noom offers 2 different plans for various needs – diabetes prevention and weight loss.

Honestly, both of them are very effective.

So this program makes a great way to lose weight (and maintain it).

Besides, it can also help you lower the risk of diabetes.

That's a major thing, trust me!



#4 – Food Categories & Meals (6 out of 10)

Let's get into more details about Noom's food color strategies.

Also – I want to give you some clear meal examples this app recommends.

1. Food Categories

As I said, Noom's top strategy is to divide foods based on their calories:

  1. Green foods (healthiest)
  2. Yellow foods (average)
  3. Red foods (unhealthiest)

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

In other words, green foods tend to have fewer calories.

On the other hand, red foods are the one with a high calorie count.

Now – most weight loss program would probably require you to give up red (and even some yellow) foods.

But that's not the case of Noom.

Instead – it gives you some clear amounts regarding the foods you should consume:

  1. 30% green foods
  2. 45% yellow foods
  3. 25% red foods

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Now, each person's plan is totally different.

But the amounts of every food color is pretty close.

You have to write down your daily foods in the app.

Once you do this – it automatically calculates your daily calories and the per cent of foods you have.

As you get used to the app, you learn the color of most foods you consume. 

So a few weeks into the program, you will understand how you should eat correctly.

That's the approach Noom uses in order to teach you how to maintain your results.

2. Meals

Unfortunately, Noom doesn't have any food-delivery options.

If that's what you're looking for, this program would make a much better alternative.

But Noom does offer some clear recipes:

  • each of them has the specified food color (green, yellow, red)
  • there's a calorie number for every one of them

In other words, all you have to do is to follow Noom's food recommendations.

It's true that it would take you some extra time and money.

Anyway – let's see some breakfast options:

  • Tropical Raspberry Smoothie
  • Avocado Egg Toast
  • Southwestern Frittata

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

Getting to the lunch recommendations, here are some:

  • Key West Grilled Chicken
  • Butternut Squash Bisque
  • Quinoa With Veggies

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

As for the lunch options you have, here are some suggestions:

  • Instant Pot Chilli Mac
  • Shrimp Egg Rol
  • Fruited Turkey Salad

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

As you can see – you have plenty of options to choose from.

But like I said, the only potential problem would be time (and money).

Still, if you're willing to follow Noom's recommendations – you definitely have a lot to choose from.

So variety won't be one of your worries.




#5 – Results (10 out of 10)

Noom has a huge number of satisfied users behind.

On the other hand, its complaints and negative reviews are a lot less.

Even though it's a pretty recent product (less than 15 years) – it has a huge number of reviews.

Given these numbers, it's safe to say this program really works for weight loss.

Note: I only considered authentic reviews, not fake/promotional ones.

1. Positive Opinions

The best thing about Noom is that it has lots of praises on trustworthy websites:

  • TrustPilot
  • Consumer Affairs
  • Apple Apps

Honestly – these sources are all extremely credible.

If this program didn't work – trust me, it wouldn't have such a huge number of reviews.

And the most impressive part is that over 80% of them are all positive:

  1. Most users praise it for its results.
  2. Others claim it's the only program that allowed them to keep their weight low.
  3. Lots of people praise its daily lessons.
  4. So many users claim Noom changed their life in an amazing way.
  5. Some even praise its diabetes program.

In other words – I was very impressed by Noom's customer feedback.

According to most of its users, it really is a life-changing program.

And it's not all about the weight (even though it really reduced it).

It's about being able to maintain that weight and learning how to do that (without using the app anymore).

Honestly, Noom deserves all the praises here.

Besides, it also has some great results in studies and it also has some going on. [3]

So it's clearly very effective and helpful.

2. Negative Opinions

For a product with thousands of reviews, Noom has very few complaints.

There are some negative opinions, that's true – but it's completely normal.

Still, as a percentage, they are very rare.

So here's what people mostly complain about:

  • long quiz
  • robot responses
  • reading lessons

Now – it's obvious that this program cannot satisfy everyone.

And it's also true that its quiz is quite long.

But that's because they need a lot of info to make the most personalized plan for you.

Other than that, the complaints are pretty minor.

And as I said, they are extremely rare (compared to the praises).


Noom has a very positive user feedback overall.

In fact, it has thousands of reviews from real users (which is a huge number).

Out of these – the complaints it has are pretty rare (and insignificant).

So in terms of customer satisfaction, it looks amazing.



#6 – Side Effects (10 out of 10)

Tolerance seems to be one of Noom's strong points.

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?That's because I couldn't find any complaints related to any side effects it could cause.

Now – this program is created as an app.

So on paper, there wouldn't be any side reactions it could cause.

However, that's not the case of other similar programs:

  • some require you to eat a very limited number of calories
  • other force you to give up certain (essential) foods
  • a few others recommend fasting

On the other hand, Noom is very flexible.

Besides, its recipes are very easy to digest (and even prepare).

Since it has no complaints on any side reactions, it's obvious that it's very well-tolerated. 

So you can count on this if you want a safe weight loss program.



#7 – Price (7 out of 10)

Pricing isn't necessarily the best thing about Noom.

However, it becomes more than affordable if you opt for a longer memberships.

You can also test it out for an insignificant amount ($1).

Anyway – its pricing isn't very simple, so let me explain it in detail.

1. The Exact Price

First of all – Noom's pricing depends on the personalized program.

But most users pay around the same rates – $70/month as a standard price.

Now, that's a bit expensive, to be honest.

But you get a much better pricing in case of a longer membership:

  • price decreases with the number of months you go for
  • standard price is $70/month
  • 6 months' price is $179 ($29/month)
  • 12 months' price is $209 ($17/month)

However, you also get some special prices for your trial:

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?

The prices above are in euro, but they depend on your location.

If you're based in the US, you can get the $14-day trial for even $1.

That's what I call a bargain…

Now – if you plan to use Noom for several months, go for a longer membership from the start.

I don't usually recommend that in first-try products.

But in this case, it's a very reputable and trustworthy program.

Besides, its price is way better with a longer membership.

So why not save a significant amount of money?

2. Worth Or Not?

It's definitely worth it.

If you're looking for a way to lose weight and maintain it – it's probably the best program.

It's super easy to use, quite affordable and it really changes your life, trust me.

It's not me saying this – it's so many people who used it:

  • changes your eating habits
  • teaches you to control your main weight loss triggers
  • allows you to lead a very healthy life
  • improves your mood and condition

If you haven't tried Noom before, you absolutely have to do it.

It's true that it doesn't include any foods or snacks, so you will have to spend some extra money on that.

So if you're on a very tight budget, it's probably not right for you.

In this case, maybe an all-in-one food & weight loss program would be better.

But if you do afford Noom, I definitely recommend trying it out.

It could potentially change your life!


Noom isn't the cheapest weight loss program out there.

So if you're tight on money, it's probably the best option for you (now).

But if you afford it, I totally recommend it.

It's the only program focused on maintaining your weight (once you lost some).

The things it teaches you are irreplaceable, so you really have to try it out if you can!




#8 – Noom In 3 Ideas

Here's how I would sum up my opinion on Noom.

1. Designed For Maintenance

Noom isn't a classic weight loss program.

Its goal is indeed to help you lose weight and get to your ideal number.

But unlike most of its competing programs, it's designed to help you maintain your weight low:

  • teaches you how to improve your eating habits
  • helps you make some behavioral changes
  • shows you how to get rid of your weight triggers

Based on its changes, lots of users managed to keep their weight (once they lost it).

Honestly, no other similar program can do that.

All of them help you lose weight – but you end up gaining it back once you give them up.

That's what makes Noom so different.

And it's a major advanatge of this program.

2. Based On Food Colors

The strategy used by Noom is very simple:

  • divides foods in 3 colors (green, yellow, red)
  • you have a (personalized) daily budget for each of them
  • the app tells classifies each food you have

Shortly – you manage to lose weight following this individual plan.

Since so many people were successful with it, it's clearly not a coincidence.

So Noom's strategy is very user-friendly and easy to follow.

But most importantly, it's effective – so it really helps you lose weight.

3. Excellent Feedback

Out of all weight loss programs – Noom is probably the one with the best user feedback:

  • over 10000 reviews from different users
  • more than 80% satisfied customers
  • very small per cent of complaints

Now, Noom has been on the market for about 15 years.

But even so, it has way more user reviews than programs with over 30 years of history.

Besides, its satisfaction rate is way higher than that of any other program.

Honestly, this speaks for itself.

Since Noom helped so many people lose weight, I'm quite sure it would also help you.



My Verdict – Is Noom Worth It?

Short answer: It's totally worth it.

My Review: Noom Diet Plan & App (For Weight Loss) - How Does It Work?It makes one of the best weight loss programs I know.

But more specifically – it's excellent if you want to lose weight AND maintain it:

  1. Teaches you how to improve weight gain triggers.
  2. Allows you to lose weight without food restrictions (and for the long run).
  3. Prevents you from gaining weight once you give up your diet.
  4. Has the highest rate of satisfied users among all weight loss programs.
  5. Works in over 80% of cases.
  6. 14-days trial costs even $1.

Now, Noom is praises by lots of people.

So I can guarantee that all these praises aren't a coincidence.

It's definitely one of the best weight loss diets from the market at this point.

Its only downside is that it doesn't include any food delivery, so you have to spend some more on that.

If you prefer a program that takes care of all your foods, you absolutely have to check this one out.

But otherwise – I totally recommend Noom.

It's the best way to lose weight and prevent it from getting back.

It's not me saying this – it's all of its previous users.

So I'm pretty sure you won't regret buying it after you get to your ideal weight!
