I am just here to remind you that hunger pains, dizziness, lack of energy, and irritability are the body's way of letting us know it's time to refuel. Busy schedules can bump eating to the last item on the to-do list. If you ignore these symptoms chances are that when you can eat, you're beyond starving. This is a recipe for disaster because hunger makes you reach for anything quick (which is usually not the healthiest thing), and you end up devouring way more calories faster than you would if you were just slightly hungry.
No matter how busy you are, you want to eat before getting to that famished point, so you can prevent overeating or feasting on unhealthy foods. Plan ahead and pack healthy meals, or schedule times of the day to eat. Also keep snacks at work, in your purse, in your gym bag, and in your car, so if you're on the road or know it'll be a while till mealtime, you can have a little something in your stomach to tide you over.
