Energy balance

Comprehensive lifestyle interventions producing modest sustained weight loss (3%-10%) yield clinically meaningful health benefits, including reduced risk of type 2 diabetes and improved cardiovascular risk factors, without requiring attainment of a normal BMI.

Focus on losing 5-10% of your body weight through a calorie-reduced diet and increased physical activity. You do not need to reach a 'normal' BMI to see major improvements in your blood sugar, blood pressure, and cholesterol. Consistency with lifestyle changes is more important than hitting a specific number on the scale.

WeakSupportsHIGH confidence
Sustained weight loss of as little as 3% to 5% is likely to result in clinically meaningful reductions in levels of triglycerides, blood glucose, and glycated hemoglobin and in risk of developing type 2 diabetes. ... It is not necessary for patients to get to a BMI of less than 25 to have a significant health benefit.
