A new pilot study shows that all 10 people with type 2 diabetes reversed their condition within 6 months using a diet program delivered entirely through an app and video calls. Participants lost an average of 37 pounds by following a very low-calorie meal replacement diet for 12 weeks, then gradually reintroducing regular foods, with their blood sugar control improving so much they no longer needed diabetes medications. According to Gram Research analysis, this eHealth approach achieved the same diabetes remission rates as previous in-person programs, suggesting digital delivery could make this treatment accessible to many more people.
A groundbreaking pilot study from Sweden shows that people with type 2 diabetes can achieve remission using a specialized diet delivered entirely through an app and video calls, without visiting a clinic in person. All 10 participants in the study reversed their diabetes within 6 months by following a very low-calorie meal replacement program for 12 weeks, then gradually reintroducing regular foods. According to Gram Research analysis, this eHealth approach worked just as well as previous in-person programs, suggesting that remote digital support could make diabetes reversal accessible to many more people who struggle to attend regular doctor appointments.
Key Statistics
A 2026 pilot study of 10 people with type 2 diabetes found that all participants achieved diabetes remission within 6 months using an app-based meal replacement program, with an average weight loss of 37 pounds and blood sugar control improving enough to eliminate the need for diabetes medications.
In the eHealth-delivered intervention study, fasting blood glucose dropped dramatically within the first week of starting the very low-calorie diet, suggesting that dietary changes, not just weight loss, contributed to improved blood sugar control.
The pilot study showed that participants’ resting energy expenditure decreased by 19% after 6 months, which is consistent with expected metabolic changes during significant weight loss.
All 10 participants in the digital diabetes reversal program tolerated the 12-week meal replacement phase without serious adverse effects, indicating that the very low-calorie diet was safe in this small study population.
The Quick Take
- What they studied: Whether people with type 2 diabetes can reverse their condition using a very low-calorie diet delivered entirely through an app, video calls, and home monitoring devices instead of visiting a clinic.
- Who participated: Ten people with type 2 diabetes diagnosed within the past 6 years, with an average age of 58.5 years and an average weight of about 230 pounds. Nine were men and one was a woman.
- Key finding: All 10 participants reversed their diabetes within 6 months, with an average weight loss of 37 pounds. Their blood sugar control improved so much that they no longer needed diabetes medications.
- What it means for you: If you have type 2 diabetes and struggle to attend clinic appointments, a digital program might help you reverse your condition. However, this was a very small pilot study, so larger studies are needed before this becomes standard treatment. Talk to your doctor before making any changes to your diabetes care.
The Research Details
This was a pilot study, which means it was a small test to see if an idea works before doing a bigger study. Researchers at Umeå University Hospital in Sweden enrolled 10 people with type 2 diabetes and had them follow a special program for 6 months. The program used an app and video calls to deliver all support, so participants never had to visit the clinic in person.
For the first 12 weeks, participants drank meal replacement shakes that totaled about 850 calories per day, which is much less than a normal diet. They measured their weight and blood sugar at home using connected devices that automatically sent the information to the research team. After 12 weeks, they gradually started eating regular food again over the remaining 4 months of the study.
The researchers stopped all diabetes medications at the start of the study and tracked whether participants could maintain normal blood sugar without medication. They also measured how many calories participants burned at rest and how their bodies used different nutrients.
Previous research showed that people can reverse type 2 diabetes through weight loss, but those studies required people to visit clinics regularly for support. This study is important because it shows that the same results might be possible using only digital tools like apps and video calls. This could make diabetes reversal available to people who live far from hospitals, have busy schedules, or prefer remote care.
This was a pilot study with only 10 participants, which is very small. It had no control group to compare results against, so we cannot be certain the app itself caused the improvement rather than other factors like motivation or diet changes. The study was conducted at a single hospital in Sweden, so results may not apply to all populations. However, the results were consistent across all participants, and the study used objective measurements like blood tests and home monitoring devices, which strengthens the findings.
What the Results Show
All 10 participants achieved diabetes remission, meaning their blood sugar control improved so much that they no longer needed medication. This was measured by a blood test called hemoglobin A1C, which shows average blood sugar over 3 months. At the start, participants had an average A1C of 7.5%, which indicates diabetes. After 6 months, their A1C dropped to 6.5%, which is the threshold for remission.
Six of the 10 participants also lost 33 pounds or more, which was the weight loss goal. On average, participants lost 37 pounds over the 6 months. The weight loss happened quickly, with most of it occurring during the first 12 weeks when participants followed the meal replacement diet.
Home measurements showed that fasting blood sugar dropped dramatically within just one week of starting the program. This rapid improvement suggests that the diet change, not just weight loss, helped control blood sugar. When researchers measured how many calories participants burned at rest, they found it decreased by 19%, which is expected when people lose weight.
The study measured how well participants’ bodies used different nutrients by looking at something called the respiratory quotient. This increased by 15% after fasting and 12% after eating glucose, suggesting that participants’ bodies shifted how they processed energy. These changes are consistent with improved metabolic health. The study also showed that participants could tolerate the very low-calorie diet for 12 weeks without serious side effects, though the study was too small to fully assess safety.
This pilot study builds on the DiRECT trial, a large study published in 2017 that showed type 2 diabetes could be reversed through weight loss using meal replacement and in-person support. The current study shows similar results using only digital delivery, which is a significant advancement. Previous research suggested that digital health programs work well for managing chronic diseases, but this is one of the first studies to show that full diabetes remission is possible through eHealth alone.
The biggest limitation is the very small sample size of only 10 people, which makes it hard to know if results would apply to larger populations. The study had no control group, so we cannot be certain the app caused the results rather than other factors. The study lasted only 6 months, so we do not know if people can maintain diabetes remission long-term. The participants were mostly men and lived in Sweden, so results may not apply to women or people from different countries. Finally, all participants were highly motivated to join a research study, so results may not reflect what happens in real-world use where motivation varies.
The Bottom Line
If you have type 2 diabetes diagnosed within the past 6 years, talk to your doctor about whether a digital meal replacement program might help you. This approach appears promising based on this pilot study, but larger studies are needed before it becomes standard treatment. Do not stop taking diabetes medications or start a very low-calorie diet without medical supervision. Work with your healthcare team to monitor your blood sugar and adjust medications safely.
This research is most relevant to people with type 2 diabetes who want to reverse their condition and prefer remote care. It may be especially helpful for people who live far from clinics, have busy schedules, or have mobility challenges. People with type 1 diabetes should not attempt this approach without close medical supervision. Pregnant women and people with certain medical conditions should consult their doctor before starting any weight loss program.
Based on this study, participants saw rapid improvements in blood sugar within the first week and achieved full diabetes remission within 6 months. However, this timeline may vary for different people. The most dramatic weight loss occurred during the first 12 weeks of meal replacement, after which weight loss slowed as participants reintroduced regular foods.
Frequently Asked Questions
Can type 2 diabetes be reversed using just an app without going to the doctor?
This pilot study suggests an app-based program can help reverse type 2 diabetes, but you must work with your healthcare team throughout the process. Your doctor needs to monitor your blood sugar, adjust medications safely, and oversee your progress. Do not attempt this without medical supervision.
How quickly does blood sugar improve on a meal replacement diet?
In this study, fasting blood glucose dropped significantly within just one week of starting the very low-calorie meal replacement diet. Full diabetes remission took 6 months, but most weight loss occurred during the first 12 weeks of the program.
Is a very low-calorie diet safe for type 2 diabetes?
In this small pilot study, all 10 participants tolerated the 850-calorie daily diet for 12 weeks without serious side effects. However, very low-calorie diets carry risks and require medical supervision. Talk to your doctor before starting any restrictive diet.
Will diabetes stay reversed after stopping the meal replacement diet?
This study only tracked participants for 6 months, so long-term remission rates are unknown. Larger studies are needed to determine how many people maintain diabetes remission after transitioning back to regular food.
Who should not try this type of diabetes reversal program?
People with type 1 diabetes, pregnant women, and those with certain medical conditions should not attempt this approach without close medical supervision. Results from this study may not apply to everyone, so discuss your individual situation with your doctor.
