Wow, I'm very interested in this stuff. Scarfing down anything prior to training is second nature to me, so I'm fascinated by the idea that really strong guys use train in a fasted state. The few times I've tried, I haven't felt good.
There was a 'Horizon' programme ( BBC's flagship science programme) last week -looking at the research into fasting, health, ageing, body composition etc.
