Working out takes energy away, so we must have energy to perform it. The reason why we can’t work out on an empty stomach is because our body needs to feed off something to produce enough energy for the workout. The 3 types of fuel that can be used for exercise are fats, carbohydrates, and proteins. Not saying, let’s go crazy and eat a bunch of fats, carbohydrates, and proteins, but you need to have some in your diet in order to make progress with your workouts!!!


Using stored body fat (meaning, fat already on the body) is a great source for long periods of exercise. Usually one gram of fat has at least 9 kcals of energy and is water insoluble. The energy source is greater than proteins and carbohydrates.


Since carbohydrates are made of carbon, hydrogen, and oxygen, they are provide the fastest form of energy, although one gram of it still provides less energy than fat. Carbohydrates come in 3 forms that use simple sugars, that are made up of glucose, fructose, and sucrose. There can also be complex carbohydrates, but start of as simple carbohydrates.


Proteins are made by using amino acids and chemical bonds. Consuming the 9 essential amino acids is a must because proteins are made up of different parts from the amino acids. Protein contributes to exercise by either directly by bioenergetics in the muscle cells or indirectly by helping synthesize glycogen to work on circulation.
