BCAA's

[jp_2011]

Well let's be honest, this former mr. Britain is probably on enough gear to fuel a space shuttle so of course he's not going to see catabolism from some fasted cardio. Now for the most of us a small amount of BCAA's (~5g) will help with catabolism during fast cardio and still allow some ffa's to be burnt up in the process.

Ye you are probably right about him being on alot of gear but in my opinion that wont make any difference. Regardless of what you take, catabolism will occur when dieting. The severaity of it will depend on your diet and training, for example 1 hour fasted cardio a day plus weight training while on very very low calories is going to cause some degree muscle loss wether your an amateur or a pro, but it will be less noticable if you have alot of muscle. BCAAs are highly insulinogenic, which destroys the whole purpose of fasted cardio.
