Why do males need more energy than females?
Generally, males require more energy than females because they have more muscle, and are bigger. This means they must have more energy to be healthy, because muscles burn energy as they work. Of course, it's not always the case that males need more energy than females. There are many other factors that influence our energy needs, besides gender. For example, common sense tells us that children and teenagers who are growing need more energy than older people, and pregnant women should have a higher energy intake than those who are not. Also, people who regularly take part in physical activity burn more energy than those who do not, so will need more energy to remain at a constant weight than those who do not exercise so often.
