Losing a significant amount of weight and following a structured exercise routine could help people with type 2 diabetes achieve remission, according to promising new research. The findings suggest that combining major dietary changes with regular physical activity may be particularly beneficial for younger adults diagnosed with the condition, CNN reports.
A study published in the scientific journal “The Lancet Regional Health – Americas” found that more than half of the participants who followed an intensive lifestyle program achieved diabetes remission within six months.
The research involved 96 adults between the ages of 18 and 45 who were living with significant excess weight and had received a type 2 diabetes diagnosis within the previous six years.
After six months, 54% of those who participated in the intensive nutrition and exercise program had achieved remission. By comparison, only 4% of participants who continued receiving standard medical care reached the same outcome.
Diabetes remission generally means that blood sugar levels fall below the threshold for diabetes and remain there for at least three months without the use of glucose-lowering medication. However, reaching remission does not mean the disease has been permanently cured. Blood sugar levels can rise again, making continued monitoring and healthy lifestyle habits important.
The lifestyle intervention involved substantial changes to participants’ eating habits, alongside a structured physical activity plan.
During the first 12 weeks, participants followed a highly restrictive diet providing between 800 and 900 calories per day. The program also included aerobic exercise and resistance training designed to strengthen muscles.
Once the initial 12-week period ended, participants gradually returned to a more conventional diet. However, they continued exercising and receiving guidance and support from specialists.
Why Early-Onset Type 2 Diabetes Is Particularly Concerning
CNN emergency medicine physician and health expert Dr. Leana Wen has explained that the condition can progress more rapidly when it develops at a younger age. It can also increase the risk of cardiovascular disease and damage to several important organs.
“A person diagnosed at age 30 can live for decades with diabetes. During this time, high blood sugar levels can damage blood vessels, nerves, kidneys and eyes,” Wen explained.
The longer someone lives with elevated blood glucose, the greater the period during which complications can potentially develop. These may include heart problems, kidney disease, nerve damage and vision difficulties.
For this reason, finding effective ways to manage the condition early could make an important difference to a person’s long-term health.
Beyond weight loss, the research highlights the importance of building and maintaining muscle strength.
Wen emphasized that muscle tissue plays an important role in regulating blood glucose levels because muscles help the body use insulin more effectively.
Resistance exercises, which include activities designed to strengthen muscles, can therefore contribute to better blood sugar management.
Why Doctors Warn Against Trying the Diet Without Medical Supervision
Despite the encouraging results, the experts stressed that the dietary approach used in the study was extremely restrictive and should not be attempted without close medical supervision.
Consuming only 800 to 900 calories daily represents a substantial reduction in food intake. For people already taking medication to control diabetes, making such dramatic dietary changes without adjusting their treatment could cause blood sugar levels to fall to dangerously low levels.
Wen recommends discussing the possibility of remission with a healthcare professional before making major changes to eating habits or exercise routines.
“I would advise that you first talk to your doctor to see if remission is a realistic goal and which method is safe for you,” she said.
Rather than attempting an extreme diet independently, people with type 2 diabetes can discuss sustainable changes that support better overall health.
Wen recommends adopting healthier eating habits, reducing sugary drinks and limiting refined carbohydrates. She also encourages including more vegetables and foods rich in fiber and protein.
Physical activity is another important part of managing the condition. Her recommendations include at least 150 minutes of moderate-intensity exercise each week, alongside muscle-strengthening activities at least twice weekly.
Researchers Say More Studies Are Needed
Although the findings offer encouraging evidence that intensive lifestyle changes can help some younger adults achieve type 2 diabetes remission, researchers caution against drawing broad conclusions from the results.
One important limitation is the relatively small number of participants. With only 96 people included, the study cannot establish whether similar results would occur across much larger and more diverse populations.
The six-month observation period is another limitation. Researchers have not yet established whether participants can maintain remission for several years or whether their blood sugar levels might eventually return to the diabetic range.
It also remains uncertain whether the same approach would produce comparable results among older adults or people who have been living with more advanced type 2 diabetes.
Further research will be needed to determine how long the benefits can last and which patients are most likely to respond to intensive lifestyle interventions.
