Caffeine in Your Blood Might Affect Body Fat and Diabetes Risk, Study Says

A 2023 genetic study linked higher blood caffeine levels to lower BMI, less whole-body fat mass, and a reduced risk of type 2 diabetes.

Researchers analyzed genetic data from nearly 10,000 people to study caffeine metabolism using Mendelian randomization.

The study found no significant association between blood caffeine levels and cardiovascular outcomes.

These findings suggest caffeine-related blood levels may affect body fat and diabetes risk, with possible implications for prevention strategies.
