9. Greek Yogurt
Whether you’re adding it to your smoothie or having it as the perfect post-workout recovery fuel, Greek yogurt will help you build muscle. This creamy snack is brimming with muscle-building protein about 20 grams in a 7-ounce cup. It has the one-two punch of vitamin D and calcium, which turn off cortisol, a stress hormone that causes the body to hang on to belly fat. Don’t believe us? Take it from the researchers at the University of Tennessee who found that people who ate 18 ounces of Greek yogurt a day lost 22 percent more weight and 81 percent more belly fat than those who didn’t.
