Energy balance

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.
