Very interesting, but not to me. All these theories about why people have gotten so fat in the last 30 years just don't seem to apply to me.

I got fat in my forties. So did my mother. So did my grandmother. So did my great grandmother. Somewhere there was a forty year old fat lady living in a cave in Europe 25,000 years ago and nobody could figure out why she got so fat. She was on a low carb diet after all.
