A while ago they found a gene affecting fat uptake in the intestines. They then said that people with the active form of this gene were more likely to be fat.

The reality is that the people with the inactive form are the mutant freaks that can't absorb vital nutrients and end up being these people that can eat what they like and stay thin.

Point being, fat gene or not....if you eat healthily and exercise you will stay thin. Coke gene or no, you can't get addicted if you never take it.

Now where's the gene for attraction to Paris Hilton?
