Noom isn’t just another restrictive meal plan; it’s a behavior-changing system that teaches you why you eat the way you do and how to make smarter choices without feeling deprived.
By combining color-coded food tracking, personalized coaching, and daily lessons you can finish in under 10 minutes, Noom creates habits that last. The results? Studies show users lose an average of 15–20 pounds in just 16 weeks, and many keep it off long-term. If you’re ready to understand your eating habits and finally take control of your health, Noom might just be the tool you’ve been searching for.
What Is the Noom Diet and Why It’s Different
The Noom diet isn’t just another calorie-counting app or a quick-fix plan. It’s a psychology-based weight loss program designed to help you build healthier habits, lose weight, and keep it off for good. Here’s what makes Noom stand out:
Behavioral Science Approach
Noom uses cognitive behavioral techniques to help you understand your eating triggers and build lasting habits, not just short-term fixes.
Color-Coded Food System
Foods are labeled as green, yellow, or red based on their calorie density and nutritional value, making it easier to make balanced choices without feeling deprived.
Daily Coaching and Support
Every user gets access to a personal coach and support group, providing motivation and guidance to stay on track.
Education Made Simple
Bite-sized daily lessons teach you how to make better decisions, control portions, and understand nutrition—without overwhelming jargon.
Proven, Sustainable Results
Studies show that many users lose 15–20 pounds in about 16 weeks, with a high success rate of maintaining their weight loss long-term.
What Are The Habits That Noom Diet Modifies
| Habit | How Noom Helps You Modify It | Example |
|---|---|---|
| Mindless Eating | Teaches you to slow down and check your hunger cues before eating. | Skipping chips while watching TV and choosing a small, healthy snack instead. |
| Emotional Eating | Helps you identify emotional triggers and offers coping strategies that don’t involve food. | Taking a short walk or journaling when stressed instead of grabbing high-calorie comfort food. |
| Portion Control | Uses the color-coded system to teach calorie density and balanced portions. | Filling half your plate with veggies (green foods) to feel full with fewer calories. |
| Inconsistent Tracking | Daily logging builds awareness of your real intake and eating patterns. | Realizing that sugary coffee drinks add 200 extra calories a day and switching to a lighter version. |
| All-or-Nothing Mentality | Promotes flexible eating to reduce guilt and binge cycles. | Enjoying pizza at a party and adjusting meals later instead of giving up on your goals. |
| Low Physical Activity | Encourages realistic, sustainable movement like walking or light workouts. | Setting a 7,000-step goal and gradually increasing it each week. |
| Unrealistic Expectations | Focuses on small, achievable goals to maintain motivation. | Celebrating a one-pound weekly loss instead of feeling discouraged about slower progress. |
How Does the Noom Diet Work: The Psychology Behind It
At its core, Noom uses behavioral psychology to help you change your relationship with food. Instead of just counting calories or banning certain foods, it teaches you why you eat the way you do and how to create healthier, more sustainable habits. This approach is what makes Noom different—and effective—for millions of users.
Behavior Change, Not Restriction
Traditional diets often fail because they rely on strict rules or temporary fixes. Noom flips the script by focusing on small, gradual changes you can maintain for life.
Example: Instead of telling you to quit desserts cold turkey, Noom might guide you to swap high-calorie treats for lighter options or reduce portion sizes, so you still enjoy your favorite foods while staying within your goals.
Mindful Eating Practices
Mindful eating is a key element of Noom. By encouraging you to log meals and eat more slowly, it helps you recognize true hunger vs. emotional cravings.
Example: You might notice that you tend to snack when you’re bored in the evening. With Noom’s daily prompts, you’ll learn to pause and ask, “Am I actually hungry, or just restless?” This small awareness shift reduces mindless snacking and supports steady progress.
Identifying Triggers
Noom helps you pinpoint emotional and situational triggers that drive overeating—like stress at work or social gatherings—and offers actionable strategies to handle them.
Example: If stress eating is your challenge, Noom may suggest alternatives like a quick walk, journaling, or deep breathing exercises to help you manage emotions without turning to food.
Positive Reinforcement and Daily Coaching
Behavioral change is hard without support. That’s why Noom pairs you with a personal coach and group community. You get feedback, encouragement, and solutions when you hit obstacles.
Example: If you hit a plateau after losing 10 pounds, your coach might analyze your logs, point out patterns (like skipping breakfast), and suggest tweaks to get you back on track.
Building a Sustainable Mindset
Noom’s ultimate goal isn’t just weight loss; it’s teaching you how to maintain your results by building a healthier mindset. Over time, you stop seeing food as “good” or “bad” and start making choices based on balance, nutrition, and your goals.
Example: Instead of feeling guilty after a slice of pizza, you’ll understand how to adjust the rest of your day—maybe by adding a lighter dinner or extra steps—to stay aligned with your plan.
The Color-Coded Food System Explained (Green, Yellow, Red)
Noom’s color-coded food system is one of its most powerful tools because it makes healthy eating simple and visual. Instead of labeling foods as “good” or “bad,” Noom groups them into green, yellow, and red categories based on calorie density and nutritional value. This approach teaches you how to eat smarter, not less—so you can enjoy a variety of foods while still losing weight.
Green Foods – Eat More of These
Green foods are low in calories but high in nutrients. These foods keep you full for longer, making it easier to stay within your daily calorie target without feeling deprived.
Examples:
- Fresh fruits like apples, berries, and oranges
- Vegetables such as spinach, broccoli, and bell peppers
- Whole grains like oatmeal, quinoa, and brown rice
- Fat-free yogurt
Tip: Noom recommends that most of your plate (about 30–50%) come from green foods to maximize volume and nutrition.
Yellow Foods – Enjoy in Moderation
Yellow foods are moderate in calorie density and provide balanced nutrition. These foods are important for energy and variety, but portion control is key.
Examples:
- Lean proteins like chicken, turkey, or fish
- Beans and legumes
- Low-fat dairy products
- Whole-grain bread and pasta
Tip: About 30–40% of your daily intake should come from yellow foods. These are your “fuel foods,” giving you the energy to stay active while supporting steady weight loss.
Red Foods – Mind Your Portions
Red foods aren’t “bad”—they’re just higher in calories, sugar, or unhealthy fats. The goal is not to eliminate them but to eat them in smaller, more mindful portions.
Examples:
- Processed snacks like chips and cookies
- High-fat meats like bacon or sausage
- Fried foods
- Desserts, sweets, and sugary drinks
Tip: Noom suggests keeping red foods to less than 25% of your daily intake. Think of these as “treats” you enjoy intentionally rather than daily staples.
Why This System Works
By focusing on calorie density—how many calories are in a gram of food—Noom helps you fill up on foods that are satisfying but won’t blow your calorie budget.
Example: One cup of strawberries (green) has about 50 calories, while one cup of ice cream (red) can top 250 calories. You could eat five cups of strawberries and still consume fewer calories than that one cup of ice cream.

Daily Coaching, Tracking, and Lessons: How Noom Keeps You Engaged
One of Noom’s biggest strengths is how it keeps you accountable and motivated every day. Instead of just handing you a calorie target, Noom provides the tools and support you need to make progress—and stick with it long-term. Here’s how:
Personal Coaching for Accountability
Every Noom user is paired with a real human coach who checks in weekly. These coaches help you set realistic goals, troubleshoot challenges, and celebrate wins, no matter how small.
Example: Struggling to stay within your yellow-food budget? Your coach might suggest meal swaps or planning tips to help you stay on track without feeling restricted.
Easy-to-Use Food and Activity Tracking
Noom’s app makes tracking simple and visual. You log your meals, snacks, and physical activity in just a few taps. Instead of just counting calories, the app shows you how your choices fit into the green, yellow, and red system, helping you learn and adjust over time.
Example: If you notice too many red foods one week, the app suggests swaps—like air-popped popcorn instead of chips—to help balance your intake.
Bite-Sized Daily Lessons
Each day, Noom delivers short, interactive lessons that take just 5–10 minutes. These lessons cover topics like mindful eating, stress management, and overcoming plateaus.
Example: A lesson might teach you about “calorie density,” showing how swapping fries for roasted potatoes can keep you full longer with fewer calories.
Progress Tracking and Visual Feedback
The app keeps you motivated with clear charts and milestones. You can see your weight trends, steps, and habit streaks, making it easier to stay engaged and celebrate progress—even during plateaus.
Example: Seeing a 10-day streak of consistent logging can boost your motivation to keep the momentum going.
Community Support
Beyond coaching, Noom includes peer groups where you can share experiences, wins, and struggles with people on the same journey. This sense of community helps you feel less alone and more encouraged.

Frequently Asked Questions
Can I follow the Noom diet if I’m vegetarian or vegan?
Yes. Noom works for vegetarians and vegans because the food system is based on calorie density and nutrition, not on specific food types. You can easily log plant-based proteins like lentils, tofu, beans, or seitan, and focus on green and yellow foods while staying within your calorie range.
Is Noom safe for people with health conditions like diabetes or high blood pressure?
For most people, yes. In fact, many users with type 2 diabetes or high blood pressure use Noom to improve their diet and activity habits. However, anyone with a medical condition should consult a healthcare provider before starting, especially if they’re on medication, to ensure that dietary changes are safe and appropriate.
How much time do I need to spend on Noom each day?
Most users spend about 10–15 minutes per day logging meals, tracking activity, and reading short lessons. This small daily commitment is designed to build consistent habits without feeling overwhelming.
Does Noom require exercise to see results?
No, but combining the program with physical activity can improve your results. Noom encourages gentle, sustainable activity like walking, yoga, or home workouts to help boost calorie burn and improve overall health, but weight loss is still possible through diet adjustments alone.
Can I use Noom if I don’t want to count calories?
Yes, but calorie awareness is part of the program. If logging every calorie feels restrictive, you can focus more on the color-coded system—prioritizing green foods, moderating yellow foods, and limiting red foods—while still benefiting from lessons, coaching, and tracking tools.
What happens after I reach my goal weight?
Noom offers a maintenance program that helps you transition from active weight loss to long-term habit management. It adjusts your calorie targets and lessons to help you maintain your progress without slipping back into old patterns.
Does Noom offer refunds if I cancel early?
Noom typically doesn’t refund unused time on subscriptions once the trial period has passed. Make sure to evaluate the program during the trial week and set reminders to cancel if you decide it’s not a good fit.
