also, I couldn't really tell, but if you're in that 3-4 th week time frame, the body really does seem to pause there. there are TONS of posts from people to whom that has happened. I was one of them. I thought to myself.. uh oh, that's it for my weight loss... but I stuck to it, and it continued. Also, at the beginning like you I could hardly eat, and had to force myself to have over 1200 ca/day. now that's no problem
I agree with what Natrushka said about calories and your metabolism and doing it in a slow but sustainable way.
