Researchers studied 295 Japanese adults who had impaired glucose tolerance, a condition often called prediabetes. They grouped these patients into three different categories based on their metabolic health. The goal was to see how well lifestyle changes helped prevent type 2 diabetes in each group.
After following the patients for up to six years, the study found clear differences between the groups. One group had the highest risk of developing diabetes, while another had the lowest risk even without extra help. The middle group had a risk level that was somewhere in between.
The most important finding was that lifestyle changes worked very well for the group with the highest initial risk. These patients saw a big drop in their chance of getting diabetes. This suggests that doctors should look closely at a patient's specific metabolic pattern before deciding on a prevention plan. This approach helps ensure that the right advice is given to the right people.
