Sometimes I wake up in the middle of the nigt and consume a protein/fat combo in the form of a shake.
Lets say I have this shake at 4 o'clock and then do mrning cardio at 8 o'clock. Would I get the benefit of burning fat on an empty stomach or would my body use that shake as my energy source?
I guess what Im trying to ask is how long should I wait between my last meal and mrorning cardio to reap the benefits of cardio on an empty stomach?
Thanks
