Study of nearly 300,000 people challenges the ‘obesity paradox’ https://www.sciencedaily.com/releases/2018/03/180315203916.htm

The idea that it might be possible to be overweight or obese but not at increased risk of heart disease, otherwise known as the ‘obesity paradox’, has been challenged by a study of nearly 300,000 people. The research shows that the risk of heart and blood vessel problems, such as heart attacks, strokes and high blood pressure, increases as body mass index (BMI) increases beyond a BMI of 22-23 kg/m2.
