Energy balance

An intensive lifestyle intervention focused on weight loss through caloric restriction and increased physical activity does not reduce the rate of major cardiovascular events in overweight or obese adults with type 2 diabetes compared to diabetes support and education.

For people with type 2 diabetes, focusing solely on weight loss through diet and exercise may not be enough to prevent heart attacks or strokes, even if it improves blood pressure and blood sugar. While lifestyle changes are beneficial for overall health and quality of life, they should not be relied upon as the sole strategy for cardiovascular protection in this population without considering other medical interventions.
