Weight Loss

So Cris, and I are gonna try to loose some weight. Starting Feb. 1st , Cris and I are having a weight loss challenge. We have til the 29th to loose as much as we can (at a healthy rate) and who ever looses the most wins. Simple right?... Well I have a problem, I LOVE fast food. I normally have In-N-Out  like 4 times a week and then we eat out during the other days of the week at different places. So to add to the challenge I told my self no more fast food. I just hope that I can do it. Wish me luck...
