Q. I do cardio everyday, but still can't lose fat. What the heck?
Excessive cardio exercise will put you in a catabolic state = break down of lean muscle mass. Mind you, One hour of running on a tredmill roughly equals 500 Calorie. If you want to burn that Big Mac meal, you'll have to run for several hours... and it's just impossible if you have a day job.

yep, muscle gets broken down. but why doesnt fat get burnt??
