I know that cardio doesn't burn muscle but I have a thought. Let's say you ate a 800 cal meal (breakfast) then went on the elliPtical for an hour and the machine reports u burned 900 cals . Also following that ur busy so u won't be able to eat, and the next time u will be able to eat it will have been 3 hours since that 800 cal meal. Since u burned more calories on the elliptical then u consumed will ur body start to break down muscle Until u eat again?
just make sure your total daily calorie intake is where it needs to be, doesnt matter if its 3 meals or 7.
“Obsessed is a word the lazy use to describe the dedicated.” -R.I.P Zyzz-
if you were on the elliptical for say, 12+ hours, everyday for a week..... i would say most likely.
your body has multiple energy systems and they overlap each other. there is no distinct line separating them.
and your body has enough immediate fuel for a few hours of exercise. and enough fat to last you days.
you can call me "ozzie" for short.
So total calorie intake is more important
I laugh every time I hear this one radio commercial "diets don't work!" followed immediately by "but MY snake-oil crap definitely does!".
