Energy does not come in a machine or a can. Real energy will get you moving throughout the day faster than a Bow-Flex or Red Bull. Energy has little to do with outputs like endurance or strength, but more importantly with inputs like food and hydration. It is more exciting for me to eat an apple, than it is to chase one. I survived my latest marathon because of the water and carbohydrates I squeezed down my gullet.
Filling your belly with energy-enriched foods is like pouring gas on a fire, your body will beg you to burn it up. Avoid drinking liquid sugar like store bought juice or energy drinks; these are the last thing you need when you are trying to increase your energy. Try to consume at least eight glasses of water per day.
Fast food is not food. Therefore, it is not energy. Think of fast food as a spoon dipped in grease, then placed on your tongue, and squeezed into your arteries. Eat fiber-rich fruits: avocados, blueberries, apples, pears, vegetables: beans, broccoli, cabbage, greens, and mushrooms. Your energy levels will increase and you will accomplish much more.
Eat healthy fats. Most people consume saturated fats and very little healthy fats. Healthy fats like monounsaturated and polyunsaturated fats are found in fish, olive oil, raw almonds, safflower oil, and avocados.
