Having the 2 cm's and 1 rm keeps insulin in check...if you start to graze you won't be keeping insulin down and therefore may not lose weight. They allow once snack but if you don't lose eating that one snack they suggest you eliminate it. I personally think I do much better with the plan without the snack. It keeps my cravings and hunger under control.

About the cheeks...the only way to know is to lose the weight and find out for yourself.
