Study finds coffee linked to testosterone, body fat and metabolism, especially in men
WZTV • • general
Key Points:
- A Finnish study of 2,264 adults found that higher coffee consumption was associated with lower body fat, more skeletal muscle, and different metabolic markers, including improved glucose-insulin profiles in men.
- Among men, increased coffee intake correlated with higher total testosterone and sex hormone-binding globulin (SHBG) but lower free testosterone, indicating a complex hormonal pattern rather than a straightforward testosterone boost.
- Women showed different hormonal responses, with higher coffee intake linked to increased SHBG and lower free testosterone but no change in total testosterone levels.
- The study was cross-sectional and relied on self-reported coffee consumption, so it cannot establish cause and effect or identify which coffee compounds might drive these associations.
- Researchers emphasize the need for long-term and controlled studies to clarify whether coffee directly causes these changes and to determine safe or beneficial consumption levels.
