Evidence-based science.


Noom is grounded in science; it is at the heart of everything we do. We have over 25 peer-reviewed scientific articles that inform users, practitioners, scientists, and the public about how our methods work and how effective they are. Our team of behavioral health experts have PhDs and masters degrees in psychology, integrative medicine, neuroscience, and statistics. We make scientific discoveries about all aspects of behavior change, making the world a healthier place. Our research spans many different areas of health, including oncology, diabetes prevention, hypertension, diabetes management, and more.

Here are some of our most recent peer-reviewed scientific journal articles.

Effect of mHealth With Offline Antiobesity Treatment in a Community-Based Weight Management Program: Cross-Sectional Study

In conjunction with local healthcare treatment, Noom reduced body weight by 2.73 kg, decreased fat mass by 2.65 kg, and significantly increased metabolic equivalent of task (MET) after 8 weeks.

Randomized Controlled Trial Comparing Health Coach-Delivered Smartphone-Guided Self-Help With Standard Care for Adults With Binge Eating

Noom plus cognitive behavioral therapy reduced binge eating days and improved remission in adults with binge eating compared to standard care.

Mobile Delivery of the Diabetes Prevention Program in People With Prediabetes: Randomized Controlled Trial

This randomized controlled trial showed that Noom’s Diabetes Prevention Program (DPP) resulted in significant weight and BMI reduction at 6 months and 12 months.

TitleYearSummary
Clinical Efficacy and Plausibility of a Smartphone‐based Integrated Online Real‐time Diabetes Care System via Glucose and Diet Data Management: A Pilot Study202040 patients with type 2 diabetes were randomly assigned to use Noom or to a control group. Significantly more patients in the Noom group achieved target A1C levels compared to the control group.
Understanding Time Series Patterns of Weight and Meal History Reports in Mobile Weight Loss Intervention Programs: Data-Driven Analysis2020Time series analysis was used to look at relationships between logging and weight loss. Logging was associated with weight loss for women but not for men.
The Effectiveness of a Monetary Reimbursement Model for Weight Reduction via a Smartphone Application – A Preliminary Retrospective Study2020In this study, participants were given a monetary reward if they logged their food three times a day. Those who logged three times a day during Noom lost significantly more weight and read more articles and exercised more compared to those who did not log three times a day.
Mobile Delivery of the Diabetes Prevention Program in People with Prediabetes: A Randomized Controlled Trial2020This randomized controlled trial showed that Noom’s Diabetes Prevention Program (DPP) resulted in significant weight and BMI reduction at 6 months and 12 months.
Relationship Between Age and Weight Loss in Noom: Quasi-Experimental Study2020Noom’s Healthy Weight and Diabetes Prevention Program both resulted in significant weight loss. Healthy Weight users lost 6.24 kg (5.2% body weight) and DPP users lost 5.66 kg (8.1% body weight) by week 52.
Randomized Controlled Trial Comparing Health Coach-Delivered Smartphone-Guided Self-Help With Standard Care for Adults With Binge Eating2020Noom plus cognitive behavioral therapy reduced binge eating days and improved remission in adults with binge eating compared to standard care.
Multi-dimensional cognitive behavior therapy for obesity applied by a clinical psychologist using a digital platform: an open-label, randomized controlled trial2020Noom with digital cognitive behavioral therapy resulted in significant weight, fat, leptin and insulin resistance, emotional eating, snack calorie intake improvements compared to a control group.
Effect of mHealth With Offline Antiobesity Treatment in a Community-Based Weight Management Program: Cross-Sectional Study2020In conjunction with local healthcare treatment, Noom reduced body weight by 2.73 kg, decreased fat mass by 2.65 kg, and significantly increased metabolic equivalent of task (MET) after 8 weeks.
Enabling Self-management of a Chronic Condition through Patient-centered Coaching: A Case of an mHealth Diabetes Prevention Program for Older Adults2019A qualitative study found that coaches trigger reflections on users’ habits, jointly help users determine measurable health goals, facilitate self-evaluations on recent behavior change, and tailor programs to adapt to users’ lifestyle and health status.
Changes in Weight and Health-Related Behavior Using Smartphone Applications in Patients With Colorectal Polyps2019In this randomized controlled trial, Noom users with colorectal polyps (a precancerous growths in the colon) lost significantly more weight than individuals who did not use Noom. Engaging with the Noom app significantly increased exercise.
Effects of Smartphone Coaching Intervention on Dietary Intake for Bariatric Surgery Candidates: A Pilot Randomized Controlled Trial2019Compared to a control condition, only Noom reduced empty calorie consumption, and total kcal and total fat intake showed larger reductions for Noom  in pre-bariatric surgery patients.
Usefulness of a Novel Mobile Diabetes Prevention Program Delivery Platform With Human Coaching:65-Week Observational Follow-Up2018Significant weight loss in pre-diabetic Noom users was sustained to 65 weeks, weight loss ranged from 6.15% to 8.98% of body weight.
Complementary Support from Facilitators and Peers for Promoting mHealth Engagement and Weight Loss2017Perceived support from groups significantly promoted Noom users’ engagement and weight loss.
Efficacy of a mobile hypertension prevention delivery platform with human coaching2017A Noom hypertension program significantly improved weight by 3.05 kg, diastolic blood pressure by 5.06 mm Hg, and hypertension category at 24 weeks.

Current Research

We are exploring all aspects of behavior change to make the world a healthier place. Here is a sample of what we’re studying and how you can participate.

Relationship with Food

Weight loss interventions can improve eating behaviors, but what about your relationship with food? We will explore in randomized controlled trial if and how Noom creates healthy relationships towards food.

Brain Activity

Developing habits and cognitive behavioral therapy (elements of Noom) improve cognitive performance and brain activity in recent studies. In this randomized controlled trial, we will see if and how Noom improves cognitive performance and brain activity.

Long-term Weight Loss 

Most people have difficulty maintaining weight loss long-term. We are running a randomized controlled trial (the most rigorous study design) to evaluate long-term weight loss and other outcomes (e.g., quality of life) using Noom.

Quality of Life Using Devices 

Most measurement of quality of life (things like stress, sleep, heart rate) is by surveys, which might not be accurate. We are going to run a randomized controlled trial to examine quality of life in Noom users as measured objectively by a device.

Science Spotlight

Can sense of smell impact health and weight? 
Cell Metabolism, 2017

A recent study showed that mice who have lost their sense of smell had faster metabolism, better fat-burning and lower obesity than mice with normal noses.

What’s going on? Olfactory neurons signal to fat tissue and promote fat build up

What does this mean? This study was in mice, too early to say whether you should start holding your nose while eating lunch. However, it does suggest that smell isn’t just about enjoying your meal, it can also trigger your body to build up fat stores.
