As part of their data analysis, the researchers also found that high levels of caffeine in the blood are associated with low weight, body fat and the risk of type 2 diabetes. “It has been estimated that regarding half of the effect of caffeine on the risk of type 2 diabetes is mediated by reducing body mass index,” the study reads. The results also “suggest that caffeine is at least partially responsible for the positive impact of coffee consumption on type 2 diabetes risk.”
