Do You Train in a Fasted State?

The idea behind the Bulletproof diet is go into ketosis, be there for a little while. Once you become keto adapted, which means you've taught your body how to burn fat, you will willingly and happily burn fat as a fuel source. If you're training every single day, training in a fasted state may actually cause so much stress on your adrenals that you might want to either take an adrenal extract or preload with some protein and some fat before you work out.
