Reaping Health Benefits from Your Daily Coffee: Insights from a Finnish Study
Your morning cup of joe might be offering more than just a wake-up call. A groundbreaking study from the University of Oulu, Finland, reveals that regular coffee drinkers tend to have less total and abdominal fat, more skeletal muscle mass, and healthier metabolic markers. This is despite having similar Body Mass Indexes (BMIs) to those who consume less coffee. The research was published on August 19, 2026, in the European Journal of Nutrition.
The study scrutinized data from 2,264 adults who took part in the Northern Finland Birth Cohort 1966 study. It was observed that individuals who consumed five or more cups of coffee daily had lower visceral fat and more muscle mass compared to those who drank less. A higher coffee intake was also linked to lower levels of branched-chain amino acids, biomarkers related to insulin resistance and the risk of type 2 diabetes, in both genders.
The results were particularly notable among men. Higher coffee consumption correlated with increased total testosterone and higher SHBG (sex hormone-binding globulin) levels. However, the researchers emphasize that this study is observational and does not establish that coffee causes these changes. More long-term interventional studies are required before these findings can influence dietary guidelines. Nevertheless, this research contributes to the growing evidence that connects habitual coffee consumption to a leaner, healthier body composition and potential long-term wellness benefits.
