How does exercise burn fat?
Fat is an essential nutrient that is vital for survival. Fat as a fuel source contains more than twice the amount of energy per gram than either carbohydrate or protein. When exercising, the body goes through several processes to deliver needed fuel to the exercising muscles. At low to moderate exercise intensity (easy to moderate difficulty), fat is used as the primary fuel source. At higher exercise intensities (hard to very difficult), carbohydrate is the main fuel source.Intensity determines fuel usedAt low exercise intensities ,fat is the primary fuel source. As intensity increases ,carbohydrate becomes a more predominant fuel source. At high exercise intensities, almost all of the fuel supplied to the muscles comes from carbohydrate.Fat burningFat is burned during exercise as fat molecules are taken into the muscles from the blood stream and used as fuel. If more fuel is required, stored fat is released into the bloodstream for the working muscles to use. This fat burning is done
