I always compare weight loss progress to others also, even though everyone says not to. I only lose 2 pounds a week also and think that is slow but look at us.....6 months later and we're over 70 pounds down. I can't complain about that at all! I just know this is working for me at this moment.
I post almost every day in the what are you eating sub forum. When I look at others food intake I know why I'm only losing 2 pounds a week. But, I'm within my portion allotment (1Cup) and get all my protein in every day so I'll continue doing what I'm doing.
Since I had my surgery and started eating regular food I've never been totally "full", I just stop eating after my 1 cup of food. I'm not full, but I'm not hungry either.
Try not to fret

Just enjoy!
