The start of the business day is an excellent time to kick your energy levels into high gear. When you wake, you need to break the fast by eating foods that replenish your body's need for energy without producing too much insulin and having trouble digesting the food. This will allow you to be both mentally and physically alert throughout the day ahead. To get the highest output of energy right from the start of your day, prepare a healthy breakfast that includes one serving of protein (examples of this includes yogurt, eggs or a protein shake), two servings of fruit (berries are good choice) and 1 serving of fiber like all bran.
