I read from this site here that hcg diet can help one lose up to a pound each day. Sure or not? Can one's body afford to lose so much each day. Maybe it's not fat that you are losing to begin with. It could be water. Water is heavy. If your body's lymphatic system is blocked, it can create water retention. I always feel that weight loss should be gradual. A sudden huge loss will send one's body into shock, and that's not good. Therefore, do adopt a healthier lifestyle. Choose your food carefully and exercise regularly. Your body will thank you for taking care of it.
