The human body receives energy from four primary sources. These include carbohydrates, fats, proteins and alcohol, in smaller amounts. Properly mixing these energy sources helps us to have a lot of energy and maintain a healthy lifestyle.See fat smash diet guide below:
Protein is used as energy in the body during endurance sports, where it is broken down and used to keep someone going. However, this usually only occurs after other major energy sources have been virtually used up. When it is being used, it often means that the person is burning into their muscles, which can be damaging for the body as it means muscle is being used for energy.
According to the Trampoline website, carbohydrates are part of foods like breads, pastas and grains like wheat. They provide large amounts of short term energy, but if this is not used immediately they turn into fats. It is stored in the muscles and liver in the form of glycogen and is a readily available fuel source for muscles after it is metabolized. People who run marathons or are about to do a large amount of constant, intense physical activity often eat a large meal of carbohydrates like pastas and beans so that they can have an excess amount of fuel over the course of their physical performance.
Alcohol is also used as human energy but in small amounts. This is because alcohol which happens to be present inside the body has calories in it and these can be used as fuel. However, unless there is always alcohol present inside the body, it doesn't a real factor in creating human energy.
Fats store just underneath the skin in a variety of places around the body. Sometimes these fats are found around the abdomen, but other times in the legs, the buttocks or the arms. Incredibly high in energy density as opposed to other energy sources within the body, fats are hard to metabolize. Fats are useful for prolonged uses of energy, as the body burns through all it's readily available energy and once depleted looks to what it has stored.
