Oh yeah, as for the "carbs inhibit lipolysis" thing, anyone interested in learning about this should google "EPOC". (Excess Post-Exercise Oxygen Consumption).

Basically, you eat some carbs so as to be able to exercise intensely, which will do a lot of good things for you (bone health, maintenance of muscle tissue, etc.), and then EPOC will take care of any calories you may have missed out on burning thanks to the carbs ingested.

(One reason why you should never do HIIT cardio fasted, by the way. Feed it as you do weight-training. But now I'm getting off-topic, )
