I did that briefly while working for a modeling agency in Brazil. It's brutal getting that last bit of fat off the mid-section and still doing decent strength-training. Most guys only did it for certain jobs, or for adding body shots to their books. It's very hard to sustain, like you say. The body only gives up those last few pounds of fat reserves begrudgingly.
All these replies and NO ONE but me jumps on Lee's casual mention of his Brazilian modeling career????? So spill it Lee....Gonna be dropping Magnum soon?
Bare Lee...He's so hot right now.
