The scientific study, which used Mendelian randomization to identify a risk factor, found that higher blood caffeine levels, due to genetic factors, were associated with reduced weight and body fat, as well as a reduced likelihood of developing type 2 diabetes.
The scientists conducted a series of additional experiments to determine whether caffeine-induced weight loss was responsible for reducing the risk of developing diabetes. In the end, they concluded that weight loss was responsible for almost half the effect of caffeine on the risk of developing this disease.
Recall that earlier scientists also found that consumption of three to five cups of coffee per day is associated with a lower risk of developing type 2 diabetes and cardiovascular disease.
