Which lifestyle factor has been shown to prevent diabetes among at-risk individuals?

The option that highlights increased physical activity and healthy eating as a lifestyle factor is correct because numerous studies have demonstrated that these two elements are crucial in preventing type 2 diabetes, particularly among individuals at risk. Engaging in regular physical activity improves insulin sensitivity, helps maintain a healthy weight, and contributes to better glucose metabolism, all of which are important in reducing the likelihood of developing diabetes.

Moreover, adopting a diet that is rich in whole foods, such as fruits, vegetables, whole grains, and lean proteins, while being low in unhealthy fats and sugars, further supports metabolic health. These dietary changes not only help manage body weight but also stabilize blood glucose levels, which reduces the risk of diabetes progression.

In contrast, options like reduced alcohol intake, increased sedentary behavior, and diets high in simple carbohydrates do not support diabetes prevention. They either neglect an active lifestyle, promote behaviors that increase the risk of diabetes, or encourage diets that can lead to weight gain and impaired glucose tolerance. Thus, focusing on increased physical activity and healthy eating is a proven strategy for diabetes prevention.
