Such great advice, Ralph!
The hardest part of sticking to Beirnstein's plan, in my opinion, is being prepared. If you don't have something low-car to grab when hunger hits you suddently, you might resort to grabbing something you'd regret later when you go to test.
I'm like you. I always grill a couple extra hamburger patties (on the George Foreman) or have a can of tuna handy for this reason.
