The Noom Diet Program: An Honest Look at What It Is, What It Costs, and Whether It Actually Works

You've probably seen the Noom ads. They're everywhere—promising that this isn't a diet, it's a lifestyle. That it uses psychology, not restriction. That you can eat the foods you love and still reach your goals. Bold claims, right?
So let's actually dig into what the Noom diet program involves, what you're paying for when you sign up at noom.com, and whether the science holds up. No hype, no sugarcoating.
What Exactly Is the Noom Diet Program?
Noom launched in 2008 as a wellness app and repositioned itself around 2016 as a psychology-driven weight management program. The core idea is that changing how you think about food is more effective long-term than following a rigid meal plan. And honestly? There's something to that.
The program is app-based. When you sign up on noom.com, you complete a questionnaire about your goals, habits, lifestyle, and health history. From there, you're given access to daily lessons (short reads on behavioral psychology, nutrition basics, and mindfulness), a food logging tool, a personal coach, and a group support community.
It's not a traditional diet in the sense that there's no specific meal plan handed to you. Instead, Noom uses a color-coded food system:
- Green foods – High volume, low calorie density. Think leafy greens, cucumbers, strawberries, broth-based soups.
- Yellow foods – Moderate calorie density. Grilled chicken, salmon, eggs, whole grains, legumes.
- Orange foods (formerly "red") – Higher calorie density. Nuts, full-fat cheese, red meat, processed snacks, fried foods.
The goal isn't to avoid orange foods entirely—it's to become aware of calorie density and build meals that are mostly green and yellow, with orange foods eaten mindfully and in smaller amounts. That's actually a reasonable framework.
The Psychology Angle—Is It More Than a Gimmick?
Here's where Noom genuinely differentiates itself. Most diet programs tell you what to eat. Noom tries to change why you eat certain things.
The daily lessons cover concepts like cognitive behavioral therapy (CBT), stimulus control, and emotional eating triggers. A 2016 study published in Scientific Reports looked at nearly 36,000 Noom users over 18 weeks and found that 77.9% reported weight loss, with the majority losing more than 5% of their body weight. That's not nothing.
But—and this is a big but—this was an internal study using self-reported data from motivated users who stuck with the program. It's not the same as a randomized controlled trial. So take those numbers with appropriate skepticism.
The behavioral education piece is genuinely useful. Understanding that you're stress-eating because of a specific trigger is different from just knowing that chips have a lot of calories. Whether you need to pay for an app subscription to learn that is a fair question.
What Does a Typical Day Look Like on Noom?
Because Noom doesn't hand you a meal plan, what you eat is largely up to you—within your daily calorie budget, which the app calculates based on your profile. Calorie targets are typically set between 1,200 and 1,600 calories per day depending on your stats and goals, which is relatively low for many people.
A reasonable Noom day might look like this:
Breakfast: Greek yogurt (plain, non-fat) with fresh berries and a drizzle of honey—mostly green and yellow, filling, and high in protein.
Lunch: A large salad with romaine, cucumbers, cherry tomatoes, grilled chicken breast, and a light vinaigrette. Maybe a piece of whole grain bread on the side.
Dinner: Baked salmon with roasted zucchini and a small portion of brown rice. Simple, balanced, satisfying.
Snacks: An apple, a handful of edamame, or carrot sticks with hummus. All logging into the app as you go.
See how this works? It's not magic. It's essentially a calorie-aware, whole-food-forward approach with a digital tool to keep you accountable. The difference is the daily behavioral lessons and the coaching layer on top.
How Much Does Noom Actually Cost?
This is where things get a little frustrating. Noom's pricing isn't exactly transparent upfront, and it changes frequently. As of 2025, here's roughly what you're looking at:
- Monthly plan: Around $60–$70/month
- 2-month plan: Around $100–$120 total
- Annual plan: Around $200–$270/year (works out to roughly $17–$22/month)
They almost always offer a trial (often $1 for 14 days or similar), which is how they get you in the door. The annual plan is the best value if you're committed, but that's a significant upfront cost before you know if the program works for you.
There's also Noom Med—a newer tier that adds access to GLP-1 medications like semaglutide (the active ingredient in Ozempic/Wegovy) through a telehealth consultation. That's a whole separate cost conversation.
What Noom Does Well (And Where It Falls Short)
The Good Stuff
The behavioral coaching framework is genuinely evidence-based. CBT applied to eating habits has solid research support. The food color system is easy to understand without requiring you to obsessively count macros. And the app's logging function is clean and simple to use.
For people who've tried every rigid meal plan and found they can't stick to one, Noom's flexible, education-first approach can feel like a breath of fresh air. The coach check-ins (even though they're not registered dietitians in most cases) provide accountability that many people need.
Where It Gets Tricky
The calorie targets can run quite low—1,200 calories is the floor for many users, which isn't appropriate for everyone, especially active individuals or taller men. Some users report feeling hungry and frustrated.
The "coach" assigned to you is typically not a licensed nutritionist or dietitian. They're trained Noom employees, which is fine for general accountability but not the same as professional nutrition guidance.
And the daily lessons, while interesting at first, can start to feel repetitive after a few months. Some users report that engagement drops off significantly after the initial weeks.
There's also the subscription model to consider. You're paying monthly for what is, at its core, a calorie logging app plus some educational content. Apps like Cronometer or MyFitnessPal offer calorie tracking for free. The behavioral content is the differentiator—but you can also find books on CBT and mindful eating for $15.
Who Is Noom Actually a Good Fit For?
Honestly? Noom works best for people who:
- Struggle with emotional or habitual eating and want structured guidance on changing those patterns
- Do better with flexibility than rigid meal plans
- Are motivated by daily engagement, lessons, and accountability check-ins
- Can afford the subscription without financial stress
It's probably not the right fit if you need specific medical nutrition therapy, have a history of disordered eating (the calorie focus and food categorization could be triggering), or are looking for a detailed, structured meal plan to follow.
A Smarter Starting Point: Know What You Actually Need
Here's the thing with programs like Noom—they're built for a general audience. The noom.com diet program uses your intake questionnaire to estimate your needs, but it's still a one-size-fits-many approach underneath the personalization layer.
Before spending $60/month on a subscription, it's worth getting clear on what kind of eating structure actually works for your body, lifestyle, and goals. If you're not sure where to start, our personalized meal planning quiz at ProperDietPlan takes about three minutes and helps you figure out what eating approach genuinely fits your life—no subscription required to get that initial clarity.
Understanding your baseline—whether that's calorie awareness, macronutrient balance, meal timing, or simply building more whole foods into your day—puts you in a much stronger position to evaluate any program, including Noom.
Practical Tips If You Do Try Noom
If you decide to give the Noom diet program a shot, here's how to get the most out of it:
Don't just chase "green." A diet of only low-calorie-density foods can leave you under-eating protein and healthy fats. Make sure yellow foods like eggs, chicken, fish, and legumes anchor most of your meals.
Actually do the daily lessons. This is what separates Noom from a plain calorie tracker. The behavioral content is where the value lives. Skim it and you're basically paying for MyFitnessPal.
Be honest with your calorie target. If 1,200 calories leaves you exhausted and miserable, message your coach and push back. You can request a higher target. Sustainable progress matters more than hitting an arbitrary number.
Use the group feature. It sounds cheesy, but peer accountability in the group chats has been cited by many users as one of the most motivating parts of the program.
Set a 3-month review date. After 90 days, honestly assess: Are you learning new habits? Is the calorie awareness becoming second nature? If yes, great. If you're just logging food mechanically, it might be time to reassign that $60/month budget.
The Bottom Line on the Noom Program
Noom isn't a scam. The behavioral psychology framework is legitimate, the food color system is practical, and for the right person, it can absolutely support healthier eating habits over time. The 2016 research is promising, even if imperfect.
But it's also not magic. The weight management results come from calorie awareness and behavior change—the same principles that work in any effective approach. What Noom sells is a structured, engaging way to learn and apply those principles. Whether that's worth $60/month is a personal call based on your budget and learning style.
If you've been stuck in a cycle of starting and stopping diets, the behavioral coaching angle might be exactly what you've been missing. If you're comfortable with nutrition basics and just need a meal plan and accountability, there are more cost-effective paths.
Either way, the most important thing is finding an approach you can actually maintain—because no program works if you quit it after three weeks.
Frequently Asked Questions
Is the Noom diet program actually effective for weight loss?
The research that exists is generally positive but limited. A 2016 study of nearly 36,000 Noom users found that close to 78% reported losing weight over 18 weeks. However, this was internal, self-reported data from engaged users—not an independent randomized controlled trial. The underlying principles Noom uses (calorie awareness, cognitive behavioral techniques, mindful eating) are well-supported by nutrition science. Whether Noom specifically outperforms other approaches with similar principles hasn't been rigorously tested head-to-head.
What foods can you eat on the Noom diet program?
Noom doesn't ban any foods. Instead, it uses a color-coded system: green foods (low calorie density, like vegetables, fruits, and broth-based soups) are encouraged in large amounts; yellow foods (moderate calorie density, like lean proteins, whole grains, and eggs) form the bulk of meals; and orange foods (higher calorie density, like nuts, full-fat cheese, and fried foods) are eaten in smaller portions. The goal is building most meals around green and yellow foods while still enjoying orange foods occasionally and mindfully.
How much does the Noom diet program cost per month?
Noom's pricing varies and changes frequently with promotions. As of 2025, a monthly plan typically runs $60–$70/month. An annual plan is significantly cheaper per month, usually working out to around $17–$22/month when paid upfront (roughly $200–$270/year). Noom almost always offers a short trial period—often $1 for the first two weeks—so you can test the app before committing to a longer subscription. Noom Med, which adds telehealth access to GLP-1 weight loss medications, is priced separately.
