Energy balance

Modest weight loss (≥5% and ≥10% of baseline body weight) significantly reduces the incidence of type 2 diabetes in prediabetic populations.

Losing just 5-10% of your body weight can significantly lower your risk of developing type 2 diabetes if you are currently prediabetic. This benefit is achieved through behavioral changes like diet and exercise, and can be enhanced with medications like orlistat or metformin.
