If you were patient, wouldn't you be able to pretty much eliminate any muscle loss if you simply kept your deficit really small? Maybe if someone had a body bugg that measured calorie output with 92% accuracy it would be plausible to lose fat w/o gaining muscle.. what do you guys think?

it's extremely easy to do so. Natural bbers do it every day. If you're taking an androgenic style of compund such as a PH it's ridiculously easy. Take time to read the wealth of info on these boards Tron. It's all for you baby!
