In a research paper published Tuesday in the scientific journal BMJ Medicine, health experts from Sweden, Denmark, and the U.K. outlined the outcome of their analysis on how caffeine intake affected body weight, cardiovascular health, and diabetes risk.

The research team used Mendelian randomization—a method of establishing cause and effect by looking at genetic evidence—to calculate predicted caffeine levels in the blood of around 10,000 participants and work out whether it was linked to BMI, body fat, and type 2 diabetes.

They found that high concentrations of caffeine in the blood was associated with a lower body mass index (BMI), the measure used to calculate whether someone is of a healthy weight, and lower body fat levels in general.
