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. Eat naturally: Focus on things that come from the earth, not a factory. The best advice is, when shopping at the grocery store, stay along the outside walls where you find fruits, vegetables, beans and lean sources of meat. All of these occur naturally. This helps keep those processed foods and sugar-packed snacks, all of which will kill your metabolism, out of the cart. Also, leave the white potatoes behind. This vegetable contains an awful lot of starch that your body converts to sugar almost immediately with little work.
