We need a consistent source of energy (calories) to function well during the day, so even if you’re too busy to feel hunger, you need to eat! This is true even if you’re trying to lose weight. Have convenient, healthy snacks on hand, such as nuts, fruit, yogurt, low fat granola bars or popcorn, whole wheat crackers or pretzels, or cheese sticks. You wouldn’t let your car run out of fuel; don’t let your irreplaceable vehicle run out either.
