Anyone have any advice on monitoring skeletal muscle mass? Since it includes water, it's going to fluctuate, which will make it a little more difficult to monitor for actual muscle loss or gain. Is there a general rule for a normal amount of water loss in skeletal muscle from 1 day to another? I plan to weigh-in 1st thing in the morning only to keep the fluctuations at a minimum, but I imagine there will still be some water changes from day to day. I'm mainly monitoring to see if I've gained any muscle rather than body fat.
