Copyright American Diabetes Association, Inc., 2010 BMI, metabolic syndrome and diabetes risk Objective: The existence of an obese sub-group, with a healthy metabolic profile and low diabetes risk, has been proposed. Yet, long term data is lacking. We aimed to investigate associations between combinations of body mass index (BMI)-categories and metabolic syndrome (MetS), and risk of type 2 diabetes in middle-aged men.
