Breakfast truly is the most important meal because it sets the stage for the rest of your day. Contrary to what some believe, eating breakfast actually helps you maintain a healthy weight. Breakfast eaters tend to eat less fat and overeat less during the day. Breakfast also helps you concentrate more effectively in the late morning, work more efficiently, and maintain a good mood. Your goal is to eat about 1/3 of your daily calories and 2 servings of fruits and vegetables in the morning.
