Think Like a Caveman
Food is energy for your body. Nothing more, nothing less. Think about your food before you eat: "Why am I eating this?” “Do I really need this?" This will help you focus on eating enough to keep you moving, and choosing foods that will give you prolonged energy. Remember, sugar is one of the worst things for your body. It provides instant glucose to your system resulting in immediate energy. A short time afterward, the glucose is gone and your body is back to craving cheap sources of energy, like more sugar. The end result is insulin release in response to that meal promoting fatigue and brain fogginess.
