Study finds intensive diet and exercise can reverse early-onset type 2 diabetes
Recent research suggests that a rigorous diet and exercise regimen can lead to remission of early-onset type 2 diabetes, a condition increasingly diagnosed among younger adults. A study published on October 1 in The Lancet Regional Health – Americas explored whether intensive weight loss combined with structured exercise could effectively manage this chronic disease in individuals aged 18 to 45, reports BritPanorama.
Type 2 diabetes, a condition affecting an estimated 38 million Americans, heightens the risk of severe complications such as heart disease and kidney failure over time. Researchers involved in the study focused on 96 participants with obesity who had been diagnosed with diabetes within the previous six years. The average participant age was roughly 38 years, with diabetes diagnoses averaging just over two years.
The clinical trial was conducted across Canada and the United Kingdom, assessing whether drastic lifestyle alterations could mitigate the rapid progression typically observed in early-onset diabetes. Participants were divided into two groups: one undergoing an intensive weight loss and exercise program, and a control group receiving standard medical care.
Dr. Leana Wen, a wellness expert, explained that early-onset diabetes usually progresses more swiftly than that diagnosed later in life, resulting in heightened risks of cardiovascular issues and premature death. Previous studies indicated that substantial weight loss could lead to remission, but most had focused on older adults. This study aimed to determine if such interventions could be equally effective for younger patients.
After six months, the outcomes were noteworthy. Approximately 54% of participants in the intervention group achieved diabetes remission, defined as a hemoglobin A1c level below 6.5% without glucose-lowering medication for at least three months. In contrast, only 4% of the control group reached this benchmark. The intervention group also recorded an average weight loss of about 16.5 pounds (7.5 kilograms) more than the control group and showed improvements in cardiorespiratory fitness.
During the initial 12-week period, participants in the intervention group adhered to a low-calorie diet, consuming between 800 to 900 calories daily. They followed meal replacement strategies for the first two weeks before transitioning into a sustainable meal framework, combined with rigorous exercise involving both aerobic and strength training sessions.
However, experts caution that such an intensive program might be challenging for the average individual to replicate safely without medical supervision. Adherence rates were also a concern, with only about 40% of participants fully meeting the program’s criteria. Wen highlighted that people considering similar approaches should consult with healthcare providers to develop realistic and safe strategies tailored to individual needs, particularly regarding calorie restriction and diabetes management.
The findings, while promising, come with limitations. The trial’s small scale and exclusion of various demographics—such as older individuals or those with more severe complications—limits its applicability. Moreover, longer-term studies are necessary to assess the sustainability of diabetes remission and the potential for weight regain.
As the discussion around diabetes management evolves, the emphasis on lifestyle interventions, including exercise and diet, will likely strengthen within healthcare strategies aimed at this growing population facing chronic health challenges.
