Energy balance

Intentional weight loss of 5-10% or more in overweight individuals significantly improves physiological markers (blood pressure, lipids, glucose) and reduces the incidence of type 2 diabetes and hypertension.

If you are overweight, aim to lose 5-10% of your body weight. This modest loss significantly improves blood pressure, cholesterol, and blood sugar. Even preventing further gain is a critical health step.

GoodSupportsHIGH confidence
For most overweight persons, the initial goal is to prevent further weight gain and then to achieve moderate reductions in weight... Among women in the Nurses’ Health Study, those who lost 11 kg (24 lb) or more had a risk of type 2 diabetes that was more than 75 percent lower than that of nurses with unchanged weight.
