Specifically, the body burns fat after first exhausting the contents of the digestive tract along with glycogen reserves stored in liver cells and after significant protein loss. After prolonged periods of starvation, the body uses the proteins within muscle tissue as a fuel source, which results in muscle mass loss.
Fat burning typically begins after approximately 12 hours of fasting and escalates between 16 and 24 hours of fasting.
