For many years, people have believed that the best way to prevent diabetes is to lose weight.
Doctors often tell patients with prediabetes to eat less, exercise more, and focus on reducing body weight. While this advice can help, a new study suggests that weight loss may not be the only path to better health.
Prediabetes is a condition where blood sugar levels are higher than normal but not yet high enough to be called diabetes. It is very common and affects a large number of adults worldwide. If not managed properly, it can lead to type 2 diabetes, which increases the risk of heart disease, kidney problems, and other serious health issues.
Despite the strong focus on weight loss, many people find it difficult to lose weight and keep it off. As a result, they may feel frustrated or discouraged, even when they are trying to improve their health. At the same time, global rates of diabetes continue to rise, showing that current approaches may not be enough.
A new study published in the journal Nature Medicine offers a different perspective. The researchers found that some people can return their blood sugar levels to normal without losing weight. This process is called remission.
In the study, about one in four people who took part in lifestyle programs were able to bring their blood sugar back to a healthy range without any weight loss. Even more importantly, these people had the same lower risk of developing diabetes in the future as those who did lose weight.
This finding challenges the idea that weight loss is always necessary for improving blood sugar. It suggests that other changes in the body may play a key role.
One important factor is where fat is stored in the body. Not all body fat affects health in the same way. Fat that builds up around the organs in the abdomen, known as visceral fat, is particularly harmful. It can cause inflammation and interfere with insulin, the hormone that controls blood sugar.
When insulin does not work properly, blood sugar levels rise. This is a key step in the development of diabetes.
In contrast, fat stored under the skin, called subcutaneous fat, may be less harmful and can even support better metabolism. The study found that people who improved their blood sugar without losing weight tended to move fat away from their internal organs and toward areas under the skin.
This shift in fat distribution may help the body use insulin more effectively, even if overall weight does not change.
The researchers also found that certain hormones play an important role. Some of these hormones help the body release insulin when blood sugar rises. These are similar to the hormones targeted by modern diabetes medications.
People who achieved remission without weight loss appeared to improve the function of these helpful hormones while reducing the effects of hormones that increase blood sugar.
This means that improving how the body works may be just as important as reducing body weight.
The findings also suggest practical steps that people can take. Instead of focusing only on weight, people may benefit from changes that improve metabolism and reduce harmful fat.
For example, certain diets, such as those rich in healthy fats from fish, nuts, and olive oil, may help reduce visceral fat. Regular physical activity, especially endurance exercises like walking, cycling, or swimming, can also help reduce fat around the organs even if body weight stays the same.
This does not mean that weight loss is unimportant. Losing weight can still improve overall health and reduce many risks. However, the study shows that it is not the only way to improve blood sugar control.
For healthcare providers, this research highlights the need for a broader approach. Instead of focusing only on weight, doctors may also consider tracking blood sugar levels and encouraging lifestyle changes that improve how the body processes energy.
There are also some limitations to consider. The study focused on people in structured lifestyle programs, which may not reflect all real-world situations. In addition, while the results are promising, more research is needed to understand how long these benefits last and how they apply to different populations.
In conclusion, this study provides new hope for people with prediabetes. It shows that improving blood sugar is possible even without weight loss. By focusing on metabolic health, fat distribution, and lifestyle habits, people may have more flexible and achievable ways to reduce their risk of diabetes.
This research, published in Nature Medicine, suggests that future treatment strategies may shift away from weight alone and toward a more complete view of health.
