So I've lost 7 lbs already... I know it isn't much, but I'm just wondering, is this water or actual fat?

I heard in the beginning of weight loss you lose mostly water, not sure how true this is though... Can anyone answer this for me? Thanks!!!

The answer is...probably both. While it's mostly water that comes off in the beginning, the fat starts to come off too.

Both--but that's what you're supposed to do!! I've read one pound of fat holds 6 pounds of water--but imagine skin that's NOT hydrated with water, and you've got beef jerky!!

yes its quite correct !!
if you lose 2 pounds , then it is the loss of 70% water and 30% fat !!
so its necessary to exercise regularly !! if you cant you get the lost weigh pretty fast !!

Very interesting... Good to know! Thank you all very much for the feedback.

To complicate matters, you're also losing muscle, too!

Wow, I had no idea that fat held on to that much water!

(sadly, I did know we lose muscle too...)
