But isn’t overweight, as defined by doctors, dangerous to health? Not necessarily, provided the overweight person is active. In The Obesity Myth (2004), law professor Paul Campos, who struggled for years with weight problems and then began to research the issue, argues that the true health risks are often distorted or exaggerated. He notes that “fat active people have half the mortality rate of thin sedentary people, and the same mortality rate as thin active people.”
But there is another interesting quote in there about how diet really does little to help overweight people maintain their weight.
