It definately wouldn't work for me. I would ballon up like the pillsbury doughboy. I tried a 60% carb diet once, and wow did I pack on the bodyfat. I didn't gain any muscle or strength though, so it was not even a fair trade off. I would personally recomend against such a diet, not becuase of the high carb intake, but because one will not produce optimal levels of anabolic hormones due to the low fat intake. Also, unless one is eating very high calories, the protien might be inadequite for optimal lbm gains.
