I guess this way of eating is to try and prevent catabolism. If your body goes for too long without food it will go into a catabolic state in which it will increase cortisol levels and start stripping away your muscle.
It might also help with fat loss long-term by keeping leptin levels up -- there are a few studies which suggest such an approach might be fruitful for that purpose.
BTW, good post about cortisol and abdominal fat. Alpha2 receptors likely play a strong role as well.
