Why Are Some People Fat and Some Thin?

Some children are fat and some children are thin. Which is better? Generally speaking, fat people have more calories than they need. The surplus calories turn into fat, which is stored under the skin, making the person look bigger and fat. Thin people generally do not get enough nutrition or they expend too much of the energy gained from their nutrition in their labours. When a per- son is ill, his or her body often consumes a lot of energy and doesn't want to eat, so he or she loses weight. But you can not tell if a person is healthy or unhealthy by how fat or thin he or she is. As long as the body organs function properly, a person will be considered healthy no matter whether he or she is thin or fat.
