I’ve recently started doing morning cardio after eating a tin of salmon and drinking a cup of coffee.
I’m showing VERY good results. But, all this time spent sweating away has resulted in some questions.
When the machine says that I’ve done X number of calories, does that mean that I’ve done X amount of work or that my body has burned X number of calories? They’re not the same, since my body is not 100% efficient at transfering food to work. I need to know this for my post-cardio supplementation.
The second question is regarding the percentage of fat burned to glycogen burned. I’m not doing HIIT. My heart-rate goes up to 180ish. I can always breathe through my nose (ie. no gasping). I’m currently assuming that it’s 50% glycogen. I’m guessing there’s no “easy” ratio, but there might be?
Finally, does caffeine alter the Fat:Carb ratio burned? I know that it causes release of FFA into the blood stream. I’m just hoping that increasing my caffeine dose will allow me to reduce my carb intake post-cardio. Thanks for your help.
