Lifestyle interventions (diet and exercise) reduce the incidence of type 2 diabetes in individuals with prediabetes, but the benefit is primarily established for those with Impaired Glucose Tolerance (IGT) and may not apply to those with isolated Impaired Fasting Glucose (IFG).
If you have prediabetes, lifestyle changes are your first line of defense. Aim for 150 minutes of moderate exercise per week and a healthy diet. Even if you don't lose the full 7% of your body weight, just meeting the exercise goal can significantly reduce your risk of developing type 2 diabetes.
GoodQualifiesHIGH confidence
all but one study [53] recruited individuals with IGT... and studies in populations with isolated IFG (without IGT) have not shown benefits of lifestyle intervention in reducing incident T2DM.
Why this rating
Based on meta-analysis of 11 trials and specific studies on isolated IFG.

- GLP-1 receptor agonists (semaglutide, tirzepatide) induce high rates of reversion to normoglycemia in individuals with prediabetes, but these benefits are largely lost upon discontinuation of the therapy.Strong
- Meeting multiple glycemic criteria (IFG, IGT, and/or elevated HbA1c) for prediabetes significantly increases the risk of progressing to type 2 diabetes compared to meeting only one criterion.Good
