Elaine, I do remember a pic from Orang showing me in a French maid's outfit!

Alas, but yes, it is just water for now. But soon it will be the fat coming off! As for your question on exercise, no one can answer that but you. Try it. If you feel weak, stop. Light exercise won't be a problem. The only thing you might have trouble with is more strenuous workouts, like jogging or weight training. I've done BFL workouts on protein days, and didn't feel "off" at all. See what works for you.
