Building new muscle when cutting

[Spyke]

We all know for most people with lower bf% it is very hard to build muscle while loosing fat.

I was talking with a guy at the gym today about this.... Now most of us can probably agree that if a guy with a higher bf% (lets say above 25%) were to cut while doing some heavy lifting he would be able to build some muscle at the same time..... So the whole cutting and not building muscle thing doesn't really apply to someone who has alot of fat... Question is this:

If Fat Freddy who is 30%bf starts lifting heavy and dieting at the same time, he will see his muscle gains slow down or stop when his bf gets around 25%, 20%, 15% or something else? We were just trying to figure out if there is a rule of thumb or some kind of cut off.

PS Hope all this makes sense

This is part of an earlier post I had...

Quote[/b] ]In my school of thought - key words "my" and "thought" is that you could have LBM gains and lose fat even at slightly lower than maintenance, and you wouldn't have to have a bf% of 25 or more. However, the rate of putting on LBM and losing fat is limited depending on your bf%, but a person with a bodyfat% in the teens can still put on LBM while eating under maintenace. I think Dan pointed out a study on this from pubmed, but that's not the point. Someone with a bf% of 15 wouldn't be able to put on as much LBM or as quick as a person with a bf% of 25 while eating at or slightly under maintenace. As long as they have ample amounts of protein and target most of that intake around pre and post workout - and eat clean (low GI, EFA's, stay hydrated, good fiber intake), then the fat resources on their body should be enough.

More or less, my answer is yes

If he continued eating the same amount, gains would slow/stop for 2 reasons:

-Less body fat to be converted to energy

-More muscle means BMR has increased, need more energy to gain.

And of course after a certain period of time RBE will set in.
