Welcome Hugh and Jeff!!!
Hugh, don't sweat the "great stuff at Shack" thing. I've found that my stomach just can't hold as much, period. Even when I eat what I now consider a lot, or way overdone, it really isn't. I just simply can't eat near as much as I used to, even if I try. They call that the stomach shrinking effect, I suppose that's as good a thing to call it as any.
I lost 20 pounds in the last 3 months, starting at 223. You're bigger than me, and from watching this thread it seems that bigger guys lose lots of weight really fast at first, then taper when they get closer to what might be their "natural weight".
As long as you're headed in a positive direction and continue working at it, I really don't think it matters how quick it comes off. Just keep hanging in there!!!
