According to a new study published in the medical field, weight loss and a structured exercise program can be effective, especially for individuals diagnosed with type-2 diabetes at a younger age. However, the study indicates that this requires very strict dietary and physical activity regimens.

The study, published on October 1 in The Lancet Regional Health–Americas journal, investigated whether a combination of intensive weight loss and structured exercise could lead to remission of type-2 diabetes in younger adults.

The study included 96 adults aged 18 to 45 who were all experiencing obesity and had been diagnosed with type-2 diabetes within the last six years. The average age of the participants was around 38 years, and they had lived with diabetes for an average of just over two years. This small-scale clinical trial was conducted at research centers in Canada and the UK.

Currently, the number of people affected by type-2 diabetes is increasing, and the incidence of this disease among younger adults is also rising rapidly. If not treated promptly, they face a long-term risk of complications such as heart disease and kidney failure.

Why is Early Onset of Diabetes a Concern?

According to Dr. Liana Wen, a health expert, emergency physician, and clinical associate professor at George Washington University, type-2 diabetes diagnosed before the age of 45 is referred to as early-onset diabetes. This type of diabetes tends to progress faster and carries a higher risk of complications compared to diabetes that appears later in life.

For example, a person diagnosed with diabetes at age 30 may have to contend with the disease for many decades. Prolonged high blood sugar levels can damage blood vessels, nerves, kidneys, and eyes. Individuals with early-onset type-2 diabetes also have a higher risk of cardiovascular disease and premature death.

Previous research has shown that significant weight loss can lead to type-2 diabetes remission, but most of these studies focused on older individuals.

The new study, however, tested whether such an approach would be effective in younger individuals. Researchers also investigated the impact of incorporating strength training exercises to preserve muscle mass while undergoing rapid weight loss.

According to Dr. Wen, strength training exercises help preserve muscle mass because muscles play a crucial role in regulating blood sugar levels.

Diabetes Remission in 54% Within 6 Months

Participants in the study were divided into two groups. One group followed an intensive diet and exercise program, while the other group continued with standard medical treatment. The results after six months were remarkable.

Among those in the intensive diet and exercise program, 54 percent achieved diabetes remission. In contrast, only four percent in the group receiving standard treatment achieved remission.

In this study, diabetes remission was defined as having a hemoglobin A1c (HbA1c) level below 6.5 percent for at least three months without the need for blood sugar-lowering medication.

Hemoglobin A1c indicates the average blood sugar level over a specific period and is considered an important indicator for measuring the effectiveness of diabetes diagnosis and treatment.

Participants in the intensive program also experienced a significant reduction in body fat. They lost an average of 7.5 kilograms (16.5 pounds) more weight than those in the standard treatment group.

Furthermore, their cardiovascular and respiratory system function improved. Key indicators included a lower resting heart rate and increased exercise capacity.

How Was the Diet and Exercise Program Conducted?

Participants in the intensive program were put on a very low-calorie diet for the first 12 weeks, consuming only 800 to 900 calories per day. For the first two weeks, they were given special meal replacement shakes instead of regular food.

After that, they were allowed one regular meal per day, but the total daily calorie limit remained between 800 and 900.

From the third week onwards, they began exercising twice a week under expert supervision, including aerobic exercises and resistance training using weights or exercise machines.

Additionally, they were required to perform aerobic exercises independently once a week. During the final 12 weeks of the program, participants were gradually reintroduced to regular eating patterns, with the main goal being to maintain the weight lost.

They continued to exercise independently. Doctors monitored their blood sugar levels and blood pressure throughout the program, adjusting medication dosages as needed.

This Method May Not Be Easy or Safe for Everyone

Although the study results are encouraging, health expert Dr. Wen advises that this should not be considered an easily adoptable method for all diabetes patients. According to her, the dietary program used in the study was very strict. Consuming only 800 to 900 calories daily can be difficult for many people and ma
