Study Links Caffeine Levels in Blood to Body Fat and Diabetes Risk

A 2023 study found that caffeine levels in the blood are linked to body fat levels, which in turn affect the risk of developing type 2 diabetes and cardiovascular diseases. The research, using genetic markers, suggests that higher plasma caffeine concentrations are associated with lower BMI and reduced risk of type 2 diabetes. However, no direct link was found between caffeine levels and cardiovascular diseases. While previous studies have shown some positive effects of caffeine on weight and fat mass reduction, more research is needed to confirm cause and effect, and to understand the long-term effects of caffeine intake.
