Sustained weight loss of 15-20% prevents type 2 diabetes in obese individuals, reducing the 2-year incidence from 6.3% to 0.2%.
Losing 15-20% of your body weight and keeping it off is the single most effective way to prevent type 2 diabetes, reducing your risk by over 95% in the short term and 80% in the long term. Focus on sustainable lifestyle changes rather than quick fixes.

In a Swedish weight loss intervention study on obesity the 2-year incidence of diabetes was 6.3% in the control group and only 0.2% in the weight loss group. This intervention study shows that >95% of new cases of type 2 diabetes among obese individuals can be prevented by a sustained weight loss.
Why this rating
Based on a specific intervention study with dramatic results (95% prevention) and long-term follow-up (80% protection at 10 years).
