Two middle-aged Finns can step on the same scale, register the same height, and produce an identical body mass index while carrying very different bodies underneath. A study of 2,264 adults published in the European Journal of Nutrition found that one thing separating them was how much coffee they drank.
Researchers at the University of Oulu analyzed participants in the Northern Finland Birth Cohort 1966, all measured at age 46 during a 2012 follow-up. People reporting the highest coffee intake had lower body fat percentage, lower total fat mass, less visceral fat, and more skeletal muscle than lighter drinkers. BMI, waist circumference, hip circumference, and waist-to-hip ratio were all comparable across the groups.
