When you lose a hundred pounds...
I think I would be happy with staying at my current weight but of course I want to lose a good bit more.

The mental part of this is maybe THE most important part, IMP. Entertaining thoughts of gaining back weight - unless it is hard-earned muscle - is not in my psyche. I had this surgery as a last ditch effort to get healthier and happier and enjoy living my life instead of watching from the sidelines and waiting to check out. I have to work everyday on the mental aspect of WL - not so much the eating, but the exercising. But I know it is a must. So, like Bob L., I don't want to even consider doing things counter-productive to my continued success. I want to stay focused on being as healthy as I can.
My choice is to get and then stay healthy. What's a healthy weight? The weight which allows me to do the things I want to do physically and the weight which makes me feel good about myself.
Everyone gets to the WALL in this WL journey where they think enough is enough. It's those that can break through the wall to get close to their healthy weight who find that life only gets sweeter the healthier we get. Just like Goldilocks there, Lance.....not too fat.....not too thin.....but just about right.

Right before I had surgery, I set a "goal" of 200 pounds for myself. I was 310 at the time, down from 320 just a couple months before. What I didn't realize at that point is that it's almost impossible to set an accurate goal weight for yourself unless you've actually been there in your adult life (I was 200+ in 6th grade so being non-obese was and is foreign to me). At 220lbs I feel great, I have gained confidence, resolved my diabetes, hypertension, and GERD; and can wear clothing from the "young men's" section if I choose among other things. I also have people telling me that I've lost enough and that I'm actually looking "too thin". Do I still want to get to 200 even? Yeah, maybe..I think my body however is happy where it is, I've been at 220 for a while now despite stepping up exersise. But, putting all of that aside if I don't lose another pound I won't feel that I've failed, I'll feel that I'm where I need to be. Regarding gaining weight, I wish I could say that I'll never put any back on, but when I am brutally honest with myself I have to admit that it is something that I will continue to struggle with. I didn't get fat by having solid steel willpower.
