What Is Noom? RDs Review How The Noom Diet Works Plus Pros & Cons

When you’re committed to losing weight, it can be overwhelming to know where to begin. Whether you need guidance on your food choices, workouts, or overall lifestyle, there certainly isn’t a one-fits-all approach for shedding pounds. There are countless weight-loss programs out there to choose from, but some people swear by Noom. What is Noom and how does it work, you ask?

Noom is an app that encourages daily behavior changes for long-term weight loss and focuses on fitness and nutrition to help users “stop dieting,” according to its website. The program purportedly taps into psychology to foster healthy habits and offers a team of health experts and coaches to guide you. Noom says its mission is to create “life-long results” and users say it taught them the educational side of successful weight loss (more on that later).

Based on your goal, Noom will assign you a personalized daily calorie count, as well as information on how to improve the way you eat, work out, and manage stress. From there, Noom uses a color-coded database that categorizes millions of food items based on their nutritional value. Nothing is technically off limits, but you’re encouraged to include more of some foods while avoiding others.

How Noom Works

Noom claims to be the “last weight-loss program you’ll ever need,” according to its website. It’s like having a trainer, nutritionist, and health coach all in one place (i.e., your phone).

Where Noom differs from other apps, however, is its focus on making behavioral changes surrounding dieting and weight loss. The app will show you, for example, the “best” foods to eat and which are better to limit. It also prompts you to read tidbits on healthy habits and rate your motivation—and will test you after.

The app may sound kind of tedious (who has time to read and take quizzes throughout the day?), but it could be the key to successful, sustained weight loss. The education elements that the app includes, like how it teaches you about calorie reduction and carb intake, as well as how to increase physical activity, have really important information if you want to lose weight in a sustainable way.

You can also receive rewards when you change your behaviors, plus you have access to social support—and positive reinforcement and accountability coaching have both been shown to help with long-term success.

The Pros And Cons Of Noom

Pros

• Some people swear by it. There are plenty of five-star reviews in the App Store. Just one example: “I was skeptical when I first started the trial. Roughly a month into this program, I have lost almost 10 pounds without much inconvenience.”
• There is some science to support Noom. Researchers analyzed data from 35,921 Noom app users over the course of about nine months and found that 77.9 percent reported they lost weight, in a 2016 study in the journal Scientific Reports. One interesting note: Those who neglected recording their dinner in the app lost less weight than those who recorded their dinner regularly.
• It holds you accountable. This is a big thing with reviewers, who point out that there are a lot of features to help keep you on track.
• It’s very specific. If you have trouble figuring out if your meals are healthy or how you should be moving on any given day, Noom can help guide you.
• It’s ideal for beginners. If it’s the user’s first attempt to lose weight they’ll feel refreshed with all the guidance the app has to offer.

Cons

• It lumps everyone into one group. If you have an underlying medical condition that prevents you from shedding weight, the app won’t know that—and that might leave you frustrated.
• It’s pricey. Noom is about $70 a month.
• It requires initiative. The app isn’t going to head to the grocery store and cook for you (or drive you to the gym), so you have to take some initiative to actually follow through with the healthy habits suggested.
• It could bring up deeper emotions. Identifying the reasons why your weight might be higher can bring up unresolved feelings that require a higher level of support. “The coaches can be helpful to a certain extent, but they can’t go to that deeper level, at least they shouldn’t be, that’s not within their scope,” says registered dietitian Karin Evans, PhD, CHES.
• It’s not recommended for those with a history of eating disorders. The app does not limit how much weight you can lose based on your personal information, which may lead to the belief that you can lose dangerous amounts of weight, says Evans.

Speak with your doc before you try it—as you should before jumping into any weight-loss program—so you’ll know if you have an issue like insulin resistance, thyroid problems, or hormone imbalances, and you can address those first.

Remember: It is what it says it is—a weight-loss app. Therefore, if you have struggled with the psychological side of weight loss in the past or have a history of eating disorders or disordered eating, it may be best to stick with one-on-one coaching with a registered dietitian.

Here’s what happens when you download the Noom app.

When you first add it to your phone, you will be prompted to answer some questions about your activity levels, age, gender, height, how often you eat, your weight, and why you want to lose weight. It also asks about your risk for conditions like diabetes and heart disease.

Noom will ask you to complete 10 mini-lessons in the next 16 weeks. Each course covers a specific theme that will provide you with the knowledge, skills, and tools to help you lose weight and “make progress far beyond the scale.” It’s up to you whether you want to spend as little as five minutes a day or up to 16 minutes a day on these learning sessions.

After two days, the program will connect you with a coach, who will reach out personally about two times a week to check in and share motivational messages to help you keep going. A few days after that, you will be assigned a group coach and peer chat group. Your group coach will moderate the chat and share weight-loss tips. They’ll sometimes also respond to individual comments, questions, and posts.

(It should be noted that Noom provides users with “health and wellness coaches” who are approved by the National Consortium for Credentialing Health & Wellness Coaches—though that doesn’t necessarily mean they are trained professionals like registered dietitians or certified trainers.)

Once your plan is set, you will get the number of calories you need to aim for every day. The app requires you to record your daily physical activity, as well as meals and snacks. It offers a step counter too, so you can monitor how much you’re walking. Noom also encourages you to log other health markers like blood glucose, blood pressure, and water intake.

A Noom weight-loss program is designed to last about four months, but it is recommended that you purchase a membership for up to 12 months at a time to maintain the results.

What can you eat on Noom?

Noom doesn’t necessarily say that certain foods are off-limits, but the company uses green, yellow, and orange color coding to let you know which foods may help or prevent you from reaching your weight loss goals.

Under ideal circumstances, about 30 percent of what you eat in a day should come from green foods, 45 percent should come from yellow foods, and 25 percent should come from orange foods.

Green foods, like fruits and veggies, are the least calorie-dense and contain the highest concentration of healthy nutrients. Yellow foods have more calories, but aren’t necessarily bad for you—think: meat and dairy. Orange foods, like processed foods and desserts, are the most calorie-dense, and the least nutrient-dense.

You can still have orange foods; the app just wants to make you aware that they’re high in calories and less filling, so you know what that means for staying within your daily calorie goal.

Examples of green foods include the following:

• Apples
• Bananas
• Berries
• Egg whites
• Non-fat dairy products
• Peppers
• Quinoa
• Spinach
• Whole-grain bread

Foods that are considered yellow include the following:

• Avocado
• Beans
• Black beans
• Chicken
• Salmon
• Whole eggs

Orange foods include things like:

• Beef
• Burgers
• Cakes
• French fries
• Full-fat dairy
• Nuts
• Nut butter
• Olive oil
• Seeds

Does Noom work for vegans and vegetarians?

“Noom’s program states that it is customizable to meet the needs and preferences of each individual user, including those who follow plant-based diets,” says Crystal Scott, RDN, of Top Nutrition Coaching. While Noom does not prescribe a specific way of eating, it emphasizes healthy eating habits, such as increasing your intake of fruits, veggies, and whole grains, which are all common parts of a plant-based diet, she adds.

Noom does have limited personalized coaching services, but they are not necessarily provided by a registered dietitian or healthcare professional, adds Kimberly Gomer, RD, a Miami-based registered dietitian who specializes in weight loss, diabetes, cholesterol, and polycystic ovary syndrome.

Can you drink alcohol on Noom?

Yes, alcohol is allowed on Noom, but in moderation. “Noom encourages users to make healthy choices and limit their consumption of alcohol, since it can contribute to weight gain and other health problems,” says Scott.

Remember: No food or drink is prohibited on Noom. It codes alcohol as an “orange” food. So, while you can drink alcohol, be mindful that it’s calorie-dense and lacks essential nutrients.

What does eating the Noom diet look like?

Here’s a three-day sample meal plan of the Noom diet from Mia Syn, RD, the owner of Nutrition by Mia.

How much does Noom cost?

The app itself is free and offers a free one-week trial, but the program requires a paid subscription after that. It’s $70 a month, but the price can vary depending on your goals and how much weight you want to lose.

Each weight loss plan is individualized, and the recommended duration of the program varies depending on how much weight you’re looking to lose, which in turn affects the total cost.

What does Noom actually do to help with weight loss?

Again, Noom doesn’t give you a daily menu or have a specific food program to follow. Instead, it asks you to input everything you eat, and it uses colors (red, green, yellow) to help you understand how healthy you’re eating.

Noom can be a good tool for weight loss because not only do they educate users on how to become a more mindful eater to support weight loss and provide tracking tools for food and exercise, they address the mental health side as well. “They use a science-based approach to help users better understand their relationship with food and even offer a personal coach for support throughout the program,” Syn says.

What do Noom reviews say?

The reviews are mostly positive. For Mary Leuthauser, 30, Noom is what finally kickstarted her weight-loss journey, and she lost 40 pounds using the app. “It taught me how to eat again, as silly as that may sound,” she said. Leuthauser also explained that the program taught her how to choose foods that “fueled my body instead of just filled me up.”

But she really stuck to the app and took advantage of all the educational resources. “Once I finished my course with Noom, all of the habits I learned actually stuck,” she said.

Haleigh Scott, 32, says that Noom was the first program that didn’t make her feel like she was being punished for the choices she made before downloading the app. Instead, she was given education on how to enjoy the foods she loved in moderation. “Having the comfort of still being able to enjoy my favorite meal and drinks encouraged me to keep going,” she explains. “I may have lost 30 pounds, but as a single mother of a two-year-old, I have found so much more.”

Katie Moczygemba, 28, a surgical trauma ICU nurse in San Antonio, Texas, said that Noom helped her develop a healthier relationship with food and overcome binge eating disorder. “It gave me great insights into why I had a tumultuous relationship with food that I couldn’t ever get past. I have since quit Noom and focus on intuitive eating, but to this day I still use many tidbits of information from their daily articles,” she said.

Emily Gonzalez, 35, a nurse who lost more than 190 pounds with Noom, says, “I love Noom because it teaches you about more than just what you eat, but also the why behind it. Instead of drastic measures like cutting carbs, prepackaged meal deliveries or totally avoiding sugar, Noom uses psychology to help you understand and build healthier habits, one small step at a time, and teaches you how to make changes to your daily food choices & physical activity to develop a sustainable healthier lifestyle and achieve weight loss success. I also love that no foods are ‘bad’ or off limits! With learning balance and moderation, your food options are limitless!”

How does Noom compare to other weight loss programs?

• WW (formerly Weight Watchers): They are similar in that they both use a food ranking system (with WW, it’s a points system, whereas with Noom, it’s a color system) to group foods as more or less nutritious. But Noom arguably gets more at the psychological factors behind weight management, and helps you explore why you have certain eating habits and choose the foods you do. WW, on the other hand, boasts a strong community that offers accountability and external support. Noom is also a little bit pricier.
• MyFitnessPal: MyFitnessPal creates a personalized calorie goal for weight loss and tracks food and exercise. It also has a large database of food (both restaurant and packaged) that allows you to create your own recipes with approximate calorie guidelines, says Gomer. However, compared to Noom which focuses on the psychology of weight loss, MyFitnessPal doesn’t give personalized guidance or professional support, she adds. Both apps are simple to use but the constant food logging of MyFitnessPal can be tedious.
• Nutrisystem: The biggest difference is that Nutrisystem offers a complete package for weight loss including a meal plan, the food itself, and an app for tracking meals with instructions, says Gomer. There is room for your own food, but most meals and snacks are provided as a four-week plan by Nutrisystem, she explains. And while the program is convenient (goodbye, grocery shopping and cooking), Nutrisystem is also pricier than Noom, starting at $10.18 a day.

So, which one is better for you? It ultimately depends on your personality and budget. Consider doing a consultation with a dietitian to help you choose, or ask friends and family who have experience with the different programs.

Who is Noom best suited for?

The ideal user is probably someone with a busy lifestyle and those who enjoy virtual support and accountability, says Gomer. Just note that Noom does not replace a health professional and it’s always best to talk with your doctor or a registered dietitian if you’re interested in losing weight, especially if you have disordered eating tendencies, she explains.

On the other hand, the program relies heavily on self-motivation and self-discipline, which may be challenging for some users, says Scott. “Those who struggle with accountability or need more structured guidance may find Noom less effective,” Scott adds.

Additionally, if you have a medical condition like polycystic ovarian syndrome that makes it harder to lose weight, you may want to skip Noom. Your medical needs may require a more structured or tailored plan, so it’s better to consult a nutritionist or your doctor.

And while Noom does offer some customization options, the program’s structure may be too restrictive or difficult to manage if you have a history of disordered eating. Scott has had clients come to her for guidance after stopping Noom due to use of the app leading them to previous disordered behaviors. “The color-coded foods can [trigger] an unhealthy relationship with food,” she says. You know your relationship with food and nutrition best!

Bottom line: Ultimately, know that different folks respond to plans differently. Some people like having a clear outline of what to eat and why, some people like working face to face with a coach, and some people like doing it all through the convenience of their phone—it really comes down to what works for you.
