And notice, based on these numbers, much more energy is actually stored in triglycerides than in proteins, glycogen or glucose. Only about 170 kilojoules are stored in glucose and 2500 kilojoules are stored in glycogen. In fact, these two quantities will last us about 24 hours. So, whereas carbohydrate storages are used up after about 24 hours so a day, fat storage can actually help sustain the processes of our cells in our body for several weeks. And that's because it makes up the predominant portion of the total energy that is readily available to the cells of our body. So we have 420,000 kilojoules of energy that is stored in triglyceride.
