I'm currently on one at the moment and stripping down nicely. However, it's quite frustrating on a couple of points.

Firstly you can get a serious lack of energy for a while (this is where cheat days come in) but also when you weight train you don't really increase size. You can also lose a little strength also. If I was bulking now (eating more calories than daily maintenance) I'd be huge. Don't get me wrong I'm a biggish size anyway at 210lbs and just have a bit around the stomach to get rid of and going to continue this cut until the end of the summer. Roll on winter and being even bigger, stronger.
