Someone who discovered weightloss and is an extremest about spreading the word on what you should do to loose weight weather you want to know or not!
When you have a friend that lost a bunch of weight and they keep pushing you to try this new diet and tell you all about it when you don't even care, that's a bornagain fatty!
