The conversion of food to energy: protein

Protein is rarely used as a fuel for energy. Its primary use is as building blocks for muscle. However, under extreme circumstances (e.g. ultra marathon running), the body will burn protein (together with fat) as a fuel source. When carbohydrate has run out and been depleted, in the case of long distance events, there is no carbohydrate to act as the pilot light to help burn fat. As a result, the body will start to break down protein in the body to act as the precursor. This is why it is so important to replenish carbohydrate stores (and maintain a high carbo diet during heavy training).

How do you convert protein foods to energy?

Protein:- Protein is rarely used as a fuel for energy. Its primary use is as building blocks for muscle. However, under extreme circumstances (e.g. ultra marathon running), the body will burn protein (together with fat) as a fuel source. It only occurs when the body is severely depleted of carbohydrate. The result is a breakdown of muscle tissue, which explains the muscle depletion of ultra marathon runners, etc. When fat is burned in the body, it likes to burn with carbohydrate. In other words, carbohydrate is used as a precursor burner. When carbohydrate has run out and been depleted, in the case of long distance events, there is no carbohydrate to act as the pilot light to help burn fat. As a result, the body will start to break down protein in the body to act as the precursor.
