Some people need more calories than others due to the amount of physical exercise that they do. The more exercise someone does, the more calories they will need, as they burn them off much faster than someone who does very little exercise.
E.g A 21 year old woman who has a job working in a office will need less calories than A 21 year old woman who is a fitness coach or a P.E teacher as they are constantly exercising and burning the calories off quicker.
Men also need more calories than women.
