It's a very thought-provoking question. I don't really know why I got fat. I think it was more a loss of self-control. At first I was slow to gain, so I thought hey, no big deal, I can keep eating like this. Now I'm kicking myself in the butt and wondering why did I ever let myself go so much. In any case, I'm pretty sure it is all history now. I do believe I can live on this plan the rest of my life.
