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.
If you’re only getting a minimal amount of sleep each night, that leaves more time for you to snack and make otherwise unhealthy decisions that could affect your weight loss. Although it will vary from person to person on how much sleep you actually need to be most effective (and therefore make progress toward your weight loss goals), the ideal number is typically 7 or 8 hours, says Dr. Cheskin.
