I've lost the same 50 lbs a few times now. I was so excited when I got into new territory the last time, I treated my success with FOOD. Yes, I didn't fix what was wrong in the first place. I needed to start looking at food as fuel. Its what my body needs to run - just like my car needs gas. I don't overfill my car, or give it diesel fuel - its not right to do that to myself. I'm working on me now. The weight is going to come off and stay off - because I'm taking care of my other life aspects. I also wasn't healthy. I have since found out what is medically wrong with me and that is being repaired. That contributed a lot to my sabotage.
