This works until it doesn't.

Professional body builders do bulk/cut/bulk/cut because after awhile you can't lose weight and put on muscle at the same time, especially if you want to get to the point of being shredded.

(well you can do it, but there is no benefit over bulking and cutting)

This comment is not responsive to mine. I am talking about minimizing muscle loss during weight loss, not losing weight and putting on muscle at the same time. And bodybuilders do exactly what I said during their cut phases -- to minimize muscle loss. (Most people losing weight on these drugs are not bodybuilders.)
