What is your bodyfat %? Change up your workouts so that your lifting heavier and doing your cardio either before work in the morning or after your lifting in the evening. This way you will keep most of your LBM. Look up some of Dr. Lonnie Lowery's stuff. Others differ with Lonnie on this subject, but I am using his methods and I am not loosing much LBM. Since injury (shoulder) I have been doing more cardio and have gone from 272 @15% to 262 at 11-12% and I feel good
Are you a personal trainer?
I'm sorry, I had to ask.
