This review looked at fourteen studies involving people with prediabetes or at risk of Type 2 Diabetes. The main goal was to see if lifestyle changes could stop or delay the disease from starting. The studies were mostly done in primary care settings where doctors see patients regularly.
When looking at the main result, the review found no clear proof that these programs prevented diabetes. The chance of getting diabetes did not drop significantly compared to usual care. This means the programs might not work as well as hoped for everyone.
Other health measures like blood sugar, body weight, and blood pressure also did not show big improvements. Some people did lose a little weight, but the numbers were not strong enough to say the programs were very effective. Safety was not a major concern in these reports.
Experts say future research should focus on better ways to screen patients and offer support. Social support and regular check-ins might help people stick to healthy habits better. The quality of evidence varies, so doctors should be careful before making big changes.
