Metabolic expert shares two key aspects to reducing diabetes risk and benefits of late diagnosis. Prof. Naveed Sattar suggests maintaining healthy weight and staying active can greatly impact diabetes prevention. Delaying diagnosis until older age can minimise complications. Lifestyle changes in 40s and 50s can delay or reverse diabetes. Key is improving muscle mass or cutting weight. Younger onset of diabetes is more harmful. Red flags include putting fat in wrong places. Making small sustainable changes can delay diabetes by up to 10 years.
