It always amazes me that scientists are doing these studies. I heard of a study in the UK that claimed obese people were obese because of a cold virus they contacted in the womb! Oye!
I can appreciate the studies, but the truth is...most of us are obese/fat because of our lifestyle -- eating too much of the wrong food and not exercising, not because of any external illesses/bacteria/viruses, etc...
I have thin friends who seem to eat all they want and never gain weight and I wonder how they can do it. How?? They're all active. They walk, run, jog, do pilates, go to the gym, play sports...something. I can eat what they eat and gain weight because I'm not doing anything to burn off what I'm eating.
