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.
Don’t let extra hours lounging in bed stand between you and a flatter stomach. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One Obesity study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans-fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
