cardio on empty stomach

[Phate]

I actually just learned that in my nutrition class. For the first 20 minutes of activity, the body use glycogen in the liver and the muscles for energy. When the body's glycogen runs out, the second option becomes for the body to break down amino acid into glycogen. However, after 20 minutes, and if the activity continued at a low-moderate pace (60-75% of MHR) then the body will use stored fat for energy.

I think it makes perfect sense to take a little protein before cardio, since that's what's gonna be used in the first 20 minutes anyways.

Also, I know I just basically repeated what Phate said. Whatever.

agreed, i've also read studies that show that fat is best burned in an oxygen saturated(that's kinda obvious since fat is oxidized) and a water super saturated environment, which makes sense as well

this supports the theory that low intensity aerobic cardio is best for fat burning

I concur.

i wish i could slow myself down, ive been doing 30 mins HIIT on empty stomac 4 to 5 days per week. i just cant help but push myself to the limit. i see the fat melting away but the scale drops ever so slightly as if im keeping all my mass so its really hard to gage my proggress other than looking in the mirror. would i be better off just keeping it slow and steady? sorry to hyjack.
