Ive been dieting since October 25th, 2007. I lost 31 pounds so far which im loving (im at 200 pounds now). basically i get up everyday and "break-fast" with a yogurt, so my metabolism doesnt shut down. i usually get on the treadmill after for an hour or hour and a half. ive been told that doing that EVERYDAY, isnt a good idea...ive been told that doing the cardio 5 days a week (or 6 maybe), is a lot better for the metabolism. i tried it twice and it looks like it works well, but im still not sure if its a myth or not. i cant imagine its BAD to do cardio everyday, but if they say its better for the metabolism to do it 5-6 days a week instead....maybe. i used to do fasted state cardio, then decided it was better to eat something before, better for metabolism.
