Nutrition is a wash. Nobody knows what anybody else should eat. However, it is so obvious that if you're really big you need to eat less. Let's see, there's a container and stuff goes into it and the container gets bigger and bigger and yes, stuff comes out of the container but stuff keeps going in and said container gets bigger and bigger... well now, maybe we need to put less in a container if we don't want to keep getting bigger. And it's so simple.
