My experience exactly. As a child, I could eat an elephant and stay very very thin, still, my mother instilled in me such a horror for fat people that I could never, ever become a fatty. I remember that she used to say that fat people have no willpower, they are unable to accomplish anything, even something as simple as stopping to stuff their faces. It is actually a good thing that this fat family praises that cousin, it will strengthen their resolution to stay thin. But the fat cannot face the truth, they never can.
