Mark, you talking about the amounts of water in muscles? Remember what percentage of your body is made of water...what, like 50-65%? muscle is more, like in the 70's. That's a lot of water. It makes sense that when calories are being restricted, the body says "oh shit" and starts taking water away from the muscles.

And JP, lots of people wish they had your problem. What's funny is that when you'r ein high school, all any kid wants to do is get bigger and it's next to impossible. AFter 20, it's pretty easy. I struggled to get above 155 all through high school and never got there. When I was 19, I went from 155 to 190 in a few months. Ever since then any prolonged period of working out consistently adds a few lbs. on. Right before my back surgery I said "screw it" to caution, did squats like crazy, in fact did everything like crazy, and ate like a pig. (and of course took my weight in painkillers after I was done because it was hell) I put at least 4 lbs. of muscle on in a few months. (and at least 3 lbs. of fat too, but whatever, I knew I was gonna get fat after surgery anyway)

What's hilarious about most people who see a personal trainer is that htey all say "oh, I don't want to get TOO big." Like you're gonna wake up one day and look like Dorian Yates or Chyna.
