Energy balance

Achieving a total body weight loss of 5% or higher in individuals with type 2 diabetes and obesity significantly improves glycemic control (reducing HbA1c) and reduces the utilization of glucose-lowering medications.

If you have type 2 diabetes and are overweight or obese, aiming to lose at least 5% of your body weight is a critical first step. This modest loss can significantly improve your blood sugar levels and may allow you to reduce your diabetes medications. Focus on sustainable lifestyle changes involving diet, exercise, and behavioral support rather than just medication adjustments.

In individuals with T2D who have obesity or overweight, modest and sustained weight reduction results in improvement in glycaemic control and decreased utilization of glucose-lowering medication. A total body weight loss of 5% or higher reduces HbA1c levels and contributes to mitigating risk factors of cardiovascular disease, such as hyperlipidaemia and hypertension, as well as other disease-related complications of obesity.
