Biggest loser update

So this is day 3 into the biggest loser challenge with Kim, Jordan and me. On Friday when I weighed in, I was at 166lbs. I weighed in this am, just for giggles and I'm at 158. What I did with 8 lbs, I have no idea. And honestly I haven't watched what I ate or anything. However, I haven't been eating as much...Just when I'm hungry, so sometimes I only eat twice a day, and I eat until I'm full, and thats it.  I know that it's not healthy to do what I'm doing, but when I eat like normal it just makes me sick. As the girls on the Army wives forum say, I'm on the depression diet. If I can get to 150, I'll be happy. 145 and I'll be ecstatic! Any less than that and I'll look anorexic...hah
