An online weight loss program called RestoreHealth helped over 5,000 patients lose an average of 5.7 pounds in six months, with 27.7% losing at least 5% of their body weight, according to a 2026 implementation study published in the Journal of General Internal Medicine. Patients using weight loss medications lost significantly more—12.5 pounds on average—demonstrating the program’s effectiveness when combined with medication.
Researchers tested a digital weight loss program called RestoreHealth with over 5,000 patients at hospitals and clinics. The program combined an app, online tools, and coaching from health experts. After six months, patients lost an average of 5.7 pounds, with nearly 28% losing at least 5% of their body weight. People taking weight loss medications lost even more—about 12.5 pounds on average. The program successfully enrolled a diverse group of patients and kept most of them engaged, suggesting it could be used at other hospitals and clinics across the country.
Key Statistics
A 2026 implementation study of 5,056 patients found that an online weight loss program called RestoreHealth produced an average weight loss of 5.7 pounds (2.5% of body weight) over six months in a diverse clinical population.
Among 5,056 patients enrolled in the RestoreHealth program, 27.7% achieved the clinically significant goal of losing at least 5% of their body weight within six months, according to a 2026 study published in the Journal of General Internal Medicine.
Patients using anti-obesity medications in the RestoreHealth program lost an average of 12.5 pounds (5.5% of body weight) over six months, more than double the weight loss of patients not using medication, a 2026 study of 5,056 patients found.
A 2026 study of 5,056 patients showed that 91.8% of those who registered for the RestoreHealth digital weight loss program actively engaged with it, demonstrating high adoption rates for online weight management in clinical settings.
The Quick Take
- What they studied: Whether an online weight loss program with an app and coaching could help people lose weight when offered at hospitals and clinics
- Who participated: 5,056 patients from primary care and specialty clinics who were overweight or obese (BMI of 25 or higher), spoke English or Spanish, and were at least 20 years old
- Key finding: After six months, patients lost an average of 5.7 pounds (2.5% of body weight), with 27.7% losing at least 5% of their starting weight. Those using weight loss medications lost significantly more—12.5 pounds on average
- What it means for you: If you’re overweight and have access to this type of program through your doctor’s office, you can realistically expect to lose several pounds over six months, especially if combined with medication. Results are modest but meaningful for health improvement
The Research Details
This was a real-world implementation project, meaning researchers tested the program in actual clinical settings rather than a controlled lab environment. Between November 2022 and October 2023, doctors at primary care and specialty clinics invited eligible patients to join RestoreHealth, a 12-month digital program.
The program had three main components: an online platform and mobile app where patients could track their progress, educational content about weight management, and personalized coaching from health professionals. Patients were encouraged to use these tools for at least six months, though the full program lasted a year.
Researchers tracked how many people signed up, how often they used the program, and how much weight they lost. They also looked at whether certain groups of patients (like those taking weight loss medications) had better results than others.
Testing programs in real clinical settings is important because it shows whether something actually works when doctors use it with their regular patients, not just in controlled research environments. This approach helps determine if a program can be scaled up and used at other hospitals and clinics. The large, diverse patient population (over 5,000 people) makes the results more representative of what might happen in other communities.
Strengths: Very large sample size (5,056 patients), diverse population including Spanish speakers, high enrollment rate (89.2% of eligible patients registered), and real-world clinical setting. Limitations: Only six months of data reported (though the program runs 12 months), no comparison group to see if results are better than other programs, and engagement decreased over time, which might affect longer-term results
What the Results Show
Among all 5,056 enrolled patients, the average weight loss after six months was 5.7 pounds, representing a 2.5% reduction in body weight. This might sound small, but research shows that losing even 5-10% of body weight can improve health markers like blood pressure and blood sugar.
More impressively, 27.7% of patients—more than one in four—achieved the meaningful goal of losing at least 5% of their starting weight. This is considered clinically significant because it’s associated with real health improvements.
Patients taking anti-obesity medications (like GLP-1 drugs) had substantially better results, losing an average of 12.5 pounds (5.5% of body weight) in the same six-month period. This suggests the program works particularly well when combined with medication.
Engagement was strong initially, with 91.8% of registered patients actively using the program. However, usage declined over the six-month period, which is typical for digital health programs. Despite this decline, most people continued to lose weight, suggesting the program had lasting effects even as engagement decreased.
Several factors predicted better weight loss results: Older patients tended to lose more weight than younger patients, people who started at higher weights lost more pounds (though similar percentages), and those who stayed engaged with the program longer had better outcomes. These patterns suggest that consistent use of the program’s tools and coaching is important for success.
According to Gram Research analysis, these results align with other digital weight loss programs, which typically produce 3-8 pounds of weight loss over six months. The addition of coaching and medication options appears to enhance results compared to app-only programs. The high engagement rate (91.8%) is notably better than many digital health programs, which often see engagement drop to 50% or lower.
The study only reports six-month results, so we don’t know if weight loss continues or is maintained over the full 12-month program. There’s no comparison group that used a different program or no program, making it unclear if RestoreHealth is better than other options. The study doesn’t explain why engagement decreased over time or how that affected long-term outcomes. Results may not apply to patients who don’t speak English or Spanish, or those without reliable internet access
The Bottom Line
If you’re overweight or obese and your doctor offers access to a structured digital weight loss program with coaching, it’s worth trying. Evidence suggests you can expect to lose 5-12 pounds over six months, with better results if you also take weight loss medication. Stay engaged with the program consistently for best results. (Confidence: Moderate to High)
This program is designed for adults 20 and older with a BMI of 30 or higher, or a BMI of 25-29.9 with heart disease risk factors. It’s particularly helpful for people who prefer digital tools and coaching over in-person visits, or those with limited access to weight loss specialists. People without internet access or those who don’t speak English or Spanish may face barriers to using this specific program
Based on this study, expect to see meaningful weight loss within the first six months of consistent program use. Most weight loss occurred in the early months, so patience is important. The program is designed as a 12-month commitment, suggesting that’s the timeframe needed for sustainable results
