Just doing cardio and running everyday won't really burn of that much fat or make you look good. I know because i tried it. My cardio went up, but my physical appearance wasn't at its best. Take a look into something called interval training. You have to make your heart rate go up and down like crazy to burn of maximum fat. Also remember this, what you eat accounts for 70% of your fitness and working out accounts for 30%.
