University of Toronto study finds full-fat dairy consumption does not increase weight or cholesterol in overweight adults

A 12-week study of 74 overweight or obese adults found that consuming three servings of full-fat dairy daily resulted in no significant weight gain or negative changes to cholesterol and insulin levels. Participants who increased dairy intake also showed improvements in blood pressure and higher levels of calcium, protein, and vitamin D.
