Your mom was right — breakfast really is a super-important meal! Numerous studies have shown that eating a healthy breakfast can help people feel better both mentally and physically during the morning hours. But before you make a beeline to the nearest doughnut shop, you should know that not just any breakfast will do. A recent study showed that only a high-protein breakfast does the trick, because protein eaten early helps to keep you feeling full and alert throughout the day. I recommend high-quality protein foods such as egg whites, low-fat cottage cheese, nonfat yogurt (especially nonfat Greek yogurt), natural nut butter, or turkey bacon, along with a high-quality carbohydrate like fruit or whole grain toast.
