Fasted cardio

[gbrice75]

is there a breaking point to where your body will go into breaking down protein for energy? i am getting to about 250cals burning, when my stomach just aches with hunger pains.

There are a few factors to consider here. I don't think you need to worry about your body dipping into dietary protein or LBM for energy if:

> intensity is kept relatively low when doing cardio in a fasted state

> you aren't running a severe calorie restricted diet (i'm talking < 1300-ish calories/day)

> your body has adequate fat stores and has no 'need' to use protein/LBM for energy

If you want to rest easy, go with some BCAA's about 15 mins before fasted cardio, and immediately after unless you have your first meal at that time.

thanks GB. i am looking into getting some purple wraath for that reason. i have a protein shake immediately after, 30g whey protein and a banana. first meal about 20 min after that. and yes, my body has plenty of fat to feed off of!

I think you'll be fine. Take note of your energy levels and strength throughout the weeks, as well as your appearance. This will give you a true indication on what's happening with your body.

Purple Wraath is awesome - it's what I used while running my IF diet and training after a 16 hour fast - and I definitely lost no LBM, strength was through the roof in fact. I'd consider complex carbs in that post-cardio meal, vs. the banana.
