Overview: What Is Noom?
Noom is a psychology-based weight loss app that combines cognitive behavioral science with AI coaching, food logging, and — as of 2025 — GLP-1 medication prescriptions through Noom Med. Founded in 2008 and headquartered in Princeton, NJ, Noom has published 40+ peer-reviewed scientific studies and holds CDC recognition as a Diabetes Prevention Program provider.
What differentiates Noom from calorie-counting apps like MyFitnessPal or Lose It is its emphasis on behavioral psychology. Instead of just tracking what you eat, Noom delivers daily lessons designed to change your relationship with food — identifying emotional triggers, building sustainable habits, and reframing thought patterns around eating. The AI coach provides personalized check-ins based on your progress.
Noom Med, launched in 2024, adds a medically supervised GLP-1 weight loss medication track. This is significant because it positions Noom as both a behavior change platform and a telehealth prescription service, competing directly with Hims & Hers ($165/month for compounded semaglutide) and traditional weight loss clinics.
Pricing Breakdown
| Plan | Price/Month | Details |
|---|---|---|
| Noom Weight (Annual) | $17.42 | 12-month plan, Psychology lessons + tracking + AI coach, Most popular plan |
| Noom Weight (Monthly) | $70 | Month-to-month flexibility, Same features as annual |
| Noom Med (Telehealth only) | $69 | Telehealth access for GLP-1 prescription without medication |
| Noom Med (Full-Dose GLP-1Rx) | $279 | GLP-1 medication included, Prescriber access, Full program support |
The annual plan at $17.42/month is reasonable for a psychology-based coaching app. The monthly plan at $70/month is expensive for what amounts to daily lessons, a food logger, and AI check-ins. Noom Med at $279/month for full-dose GLP-1 medication is competitive with branded alternatives ($1,800+) but significantly more expensive than Hims & Hers compounded semaglutide ($165/month).
Important GLP-1 regulatory note: Compounded semaglutide is under FDA scrutiny as of 2026. The FDA has been evaluating the safety and legality of compounded GLP-1 medications, which could affect both Noom Med and Hims & Hers pricing and availability. Users considering the GLP-1 track should discuss options with their primary care physician.
Clinical Evidence
Noom has the strongest clinical evidence base of any weight loss app, with 40+ peer-reviewed publications. A randomized controlled trial showed 75% of participants maintained 5% body weight loss at one year — a clinically meaningful threshold. The CDC-recognized Diabetes Prevention Program (DPP) status further validates Noom's efficacy for metabolic health.
However, critics note that Noom's program content may be more standardized than it appears. Multiple users report receiving similar program content regardless of their individual intake answers, suggesting the "personalization" is less granular than marketed.
AI Features
- AI health coach for personalized daily check-ins and feedback
- Behavioral pattern analysis for weight loss triggers
- Personalized lesson path generation based on psychology profile
- Food logging AI with caloric and nutritional analysis
- GLP-1 candidate identification and medical pathway AI
The AI health coach provides daily check-ins and feedback, but user reviews consistently describe these interactions as scripted and generic rather than truly adaptive. The food logging AI with color-coded categorization (green/yellow/red) is useful but oversimplifies nutrition for users with specific dietary needs.
Pros & Cons
Strengths
- ✓ 40+ peer-reviewed publications — strongest clinical evidence
- ✓ CDC-recognized Diabetes Prevention Program
- ✓ Psychology-first approach builds sustainable habits
- ✓ Noom Med GLP-1 medication track
- ✓ Annual plan is reasonably priced ($17.42/mo)
Weaknesses
- ✗ Difficult subscription cancellation — BBB warning issued in 2020; recurring billing complaints
- ✗ AI coach responses can feel scripted and generic
- ✗ Critics allege similar program content regardless of individual intake answers
- ✗ Sharing user data with third parties including Facebook (FTC concerns similar to Cerebral era)
- ✗ Noom Med is expensive ($279/month for GLP-1) vs alternatives
- ✗ Color-coded food system oversimplifies nutrition for some users
- ✗ Users report cancellation charges after free trial without clear consent
Verdict
Noom earns our recommendation as the best AI-powered weight loss app for users who want a psychology-based approach rather than pure calorie counting. The clinical evidence is genuinely strong (40+ publications, CDC recognition), and the annual pricing is fair. The Noom Med GLP-1 track adds a medically supervised option, though users should weigh regulatory risks and discuss with their doctor.
The main drawbacks are the difficult cancellation process (a recurring complaint across BBB and Trustpilot), the generic AI coach responses, and the expensive monthly plan. Start with the annual plan if you commit — the monthly rate is not worth it.
