That is pretty obvious, but doesn't mean that genes have no effect. A certain gene might make you feel hungry more, and will make you eat more, and will make you bigger. Another gene might cause someone to prefer certain foods, and again cause a difference in body weight. Pretending that everyone is the same is pointless. Someone who doesn't feel hungry much might say, it's easy, just eat less.
