A carefully supervised combination of a low-calorie diet and structured physical exercise has helped more than half of younger adults with type 2 diabetes achieve remission within six months, according to a new international clinical trial.

The study, conducted by researchers from Canada and the United Kingdom, offers encouraging evidence that intensive lifestyle interventions could make a meaningful difference for people diagnosed with diabetes at a relatively young age.

Published in The Lancet Regional Health – Americas in October 2026, the research found that 54% of participants following the combined programme achieved diabetes remission, compared with just 4% of those receiving usual medical care.

The findings are particularly important because type 2 diabetes diagnosed before the age of 45 can progress rapidly and expose patients to complications over a longer period of their lives.

International Research Examines a New Treatment Approach

The clinical trial, known as RESET for Remission, involved 96 adults between 18 and 45 years of age who had type 2 diabetes and obesity.

Researchers recruited participants through medical centres associated with the University of Leicester in England, McGill University in Montreal and the University of Alberta in Canada.

Participants were divided into two groups. One received standard medical care, while the other followed an intensive programme combining calorie restriction, supervised workouts and a structured plan for maintaining weight loss.

The researchers wanted to determine whether combining dietary changes with regular physical activity could help younger patients achieve remission while also protecting muscle strength and overall fitness.

How the Six-Month Programme Worked

Participants in the intensive intervention group initially followed a low-energy diet providing approximately 800 to 900 calories per day for 12 weeks.

During the first two weeks, meal-replacement products formed the main part of their diet. Participants gradually introduced selected regular meals while continuing to follow the calorie-restricted programme.

Exercise was another essential part of the intervention.

Participants completed supervised aerobic and resistance-training sessions twice a week, along with an additional independent workout each week during the initial phase.

For the following 12 weeks, they moved towards a healthier weight-maintenance diet while continuing physical activity.

The programme was conducted under medical supervision, including careful management of diabetes and blood-pressure medications.

More Than Half of Participants Achieved Remission

The results showed a substantial difference between the two groups.

Out of 50 participants assigned to the intensive diet and exercise programme, 27 achieved remission after 24 weeks, representing 54%.

In comparison, only two of the 46 participants receiving usual care achieved the same outcome, equivalent to approximately 4%.

For the study, remission meant that participants had blood sugar levels below the diagnostic threshold for diabetes and had remained off glucose-lowering medication for at least 12 weeks.

The intervention group also lost an average of 7.5 kilograms more than the standard-care group.

These findings suggest that a carefully managed lifestyle programme can help some younger adults achieve significant improvements in blood sugar control within a relatively short period.

Exercise Helped Address the Problem of Muscle Loss

One important feature of the research was its focus on preserving muscle during rapid weight reduction.

Very low-calorie diets can cause people to lose muscle along with body fat. This can become a concern because maintaining muscle strength is important for physical function and long-term metabolic health.

Researchers incorporated resistance exercises into the programme to help participants maintain muscle while reducing excess body fat.

Assessments showed that the intervention group achieved substantial fat loss while largely preserving muscle volume. Participants also experienced improvements in physical fitness, muscle quality and cardiovascular health.

The findings suggest that weight reduction programmes may offer broader benefits when dietary changes are combined with appropriately structured exercise.

What Makes Early Diabetes Treatment Important?

Type 2 diabetes diagnosed at a younger age can create a considerable health burden. People affected may spend more years living with elevated blood sugar and face an increased risk of developing complications involving the heart, kidneys, eyes and nerves.

Achieving remission could potentially reduce some of these risks and improve long-term health prospects.

The new study therefore highlights the importance of identifying effective treatment strategies for younger adults rather than relying exclusively on approaches traditionally developed for older patients.

Researchers Warn That Remission Is Not a Permanent Cure

Despite the encouraging results, scientists emphasise that diabetes remission does not necessarily mean the disease has been permanently cured.

Blood sugar levels can rise again, particularly if weight is regained or other metabolic problems return.

The intensive programme also had some side effects. Participants commonly reported temporary problems such as constipation, headaches, dizziness and fatigue, particularly during the early stages of calorie restriction.

No serious adverse events were reported in the trial, but the researchers stress that such a restrictive diet should never be attempted without appropriate medical supervision.

Another limitation is that the study did not include a separate diet-only group. Therefore, researchers cannot conclusively determine how much of the benefit came specifically from exercise rather than calorie restriction or the combination of both.

A Promising Development in Diabetes Management

The RESET for Remission findings provide fresh evidence that intensive lifestyle interventions can help some younger adults with type 2 diabetes achieve remission.

The researchers believe the results justify larger studies to examine whether the benefits can be maintained over several years and whether the programme can be introduced more widely in routine healthcare.

As early-onset type 2 diabetes continues to be a growing health concern, the study offers a promising direction for treatment strategies that combine nutrition, physical activity and medical support.

Although further research is necessary, the results underline an important message: early intervention and a structured approach to lifestyle changes may significantly improve the health outlook for some people living with type 2 diabetes.
