Mr. X,
How much of that initial water loss do you tend to gain back during the carb up? In my experience I tend to sometimes be a little heavier on the monday following the first carb up.. I attribute this to the supercompensation of the muscles filling with glycogen. I know I'm still down fat which is all that really matters, but if you're not expecting it, it can scare you. After that first week, I find that my water gain isn't as great when compared to my fat loss. Just for fun weigh yourself on the evening before you carb up and then the morning after it, and watch the change. The key with a CKD is to measure at the same time each week, so the water is always there when you weigh or never there. Don't weigh everyday. I suggest weighing on the morning immediately following the carb up each day. What are your thoughts on this?
