From the sounds of it he ate and trained with a bulk diet for many years.
He did PWO shakes, huge amounts of protien, and high cals.
Then he cut down. He spent years getting muscle mass from exactly what he advocates against.
Just because he eventually decided to cut and get a tan doesn't mean what hes saying is true, all his results are from a traditional approach, that he abandoned only after gaining the benefits from it.
And just for the record, hes in decent shape at best.
