Lookin good there hotrod. Yep, it's normal. You're losing fat and a little muscle. It's really hard to maintain ALL your muscle, especially if you have a lot of weight to lose. Your body needs to adjust to that kind of shock. Keep it up. You'll put the muscle right back on. Just get the weight off and then revamp the diet (slowly) so you can lift BIGGER. Are you lifting BIG and increasing weight on those lifts or just staying the same weight-wise. BTW, I've got ya beat, I'm your 59-year-older sister. HA. My pic is after working out for 6 mos. I have fat to lose too.
