If you feel your energy level fading, it may be time for an energy break. Eating a healthful snack goes a long way to refueling your body and helping you stay productive and patient. Some people like to eat small meals every few hours while others find it better to eat three meals and a snack in the afternoon. Just as your car needs to be fueled periodically when driven, your body needs periodic and regular energy consumption to be able to produce energy for the tasks at hand; have planned snacks to avoid impulse eating from the vending machines, a co-workers candy dish or your child's plate.

Watch your caffeine.
