Quizplus · Accepted Answer

During times of rest and low-intensity exercise, the body relies predominantly on stored fat as a source of energy. Fat provides more energy per unit than carbohydrates and is thus an efficient energy source during prolonged exercise. Protein is not a primary energy source and is only used for energy under extreme conditions such as prolonged starvation or in cases where the body is unable to use carbohydrates or fat for energy. Vitamins and water are essential for proper body function, but they are not a significant source of energy for muscles.
