EDIT: You must eat when hungry. If you don't the body goes in to starvation mode and will slow your metabolism. Then next time you eat you won't burn it off as quickly so you'll become tired and actually end up storing more fat.
I normaly don't eat for the 12 hours im at work and then have a large pasta meal or something when i get home. I am getting rid of about 2 pounds a week, and i sit on my *** all day long with work so thats not too bad?
