Excellent advice Biki... you are a Health Advisor in waiting..
Bunny, everything Biki said is right on. You should wait 3 weeks to begin exercising if you weren't before you started. If you were, cut it in half for 3 weeks then work back up to it. Overexertion when your body is undergoing such a drastic change in caloric and nutritional intake can actually damage the body. As Biki said, patience will do you good.
I was weighing everyday, but I learned that my weight fluctuates on a day to day basis no matter how good I think I have been. By the end of the week though, I've lost.
Given you are at day 10, you will note quicker weight loss overall during the first couple of weeks then it will level out to the average of what you will get as you continue. Some lose 10 lbs the first week (or more), then it drops to 2-5 a week and people start to freak out. Don't let a slow or decrease bother you. As long as you are losing, you are getting healthy.
Keep at it and keep shakin'
