Is Fasting a Muscle Building Exercise?

Fasting on its own is very muscle sparing, but you need make sure the if you're going to do a very intense training session. If i pull carbs on that guy, his intensity in the gim when he's doing the weights is going to be torn. And intensity is actually a more important driver keeping muscle on your body than fasting. One of somebody i'm trying to cut. That's a body builder. They have to keep the training intensity up or else their body doesn't get that kick on ass and they just can't push as hard anymore....
