According to the authors of a 2019 study published in Frontiers in Nutrition, milk and whey protein eaten by people who are doing resistance training can increase muscle strength and size and optimize body composition in both women and men. Since Greek yogurt contains similar nutrients as milk, but is higher in protein, they wanted to learn how it might influence these factors.
In the study, 30 untrained, university-aged men ate either fat-free, plain Greek yogurt containing 20 grams of protein per dose or a protein-free placebo. After doing resistance training and plyometric training three days a week for 12 weeks, the young men who ate Greek yogurt experienced more improvements in strength, muscle thickness, and body composition than the placebo group. This, along with its probiotic content and nutritional value, led the researchers to suggest that it would be a good post-workout food.
