1.1 lb gain? That sounds like me. I always gain back some weight the second day after a steak day. I've never gained back 1.1, but this morning I gained back .6. The only thing I can think of at this point for me, other than my bowel problems, is that eggs are a problem. The only day where my weight actually stayed the same for two days in a row was when I didn't eat any eggs and I don't know why I didn't notice that before (for some reason I thought I responded okay to eggs?). If eggs are my real problem, then that's going to suck for me because eggs are how I make sure to get in enough protein--2 eggs and 2 or 3 egg whites for breakfast.
