For years, the advice to the overweight and obese has been that we simply need to eat less and exercise more. While there is truth to this guidance, it fails to take into account that the human body continues to fight against weight loss long after dieting has stopped. This translates into a sobering reality: once we become fat, most of us, despite our best efforts, will probably stay fat.
The article is about growing evidence of "biological determinism." But don't let it upset your good intentions. There's plenty of research, too, that says eating healthily and getting lots of exercise prolongs life even for people unable to avoid being fat.
