I will try to respond in place of Trainer Dan. YES, LBM helps fat loss because per-pound of LBM you burn x amount of calories more (i knew x at one point), so muslce helps lose fat essentailly. Now, the question of you wanted to BULK to get more LBM, so then you could burn fat more efficiently, I am not sure if this is like chasing a rabbit in circles or not. Anyways, if you are feeling all tired like that, it probably is a good idea to chang something caus you dont' want to go on like that

ight then good luck

Your welcome in advance!
