Both fats and carbohydrates are energy giving food nutrients and both contain carbon, hydrogen and oxygen, but the molecular structure of fat is more complex than that of carbohydrates. Carbohydrates breaks down to form carbon dioxide and water and water and releases energy. Combustion of fat takes a long period of time and hence carbohydrates are preferable to fats.
