I too have repeatedly heard and read that loosing a lot of weight in a short time is quite unhealthy, and makes you much more prone to gaining that weight back later on. In general, the body dislikes sudden, dramatic changes. Among other things, I suspect loosing a lot of fat in a short time would significantly disturb one's hormonal balance, which is unlikely to make you feel better. I agree with abuelitodimetu that the more you weight, the more you loose when you start working out and all, but 15 pounds a week for a few weeks is frightening.
