I did some research on the structure. Here's how I'm going to work it. During the week I normally eat a lot of the same things, so I think I can do this fairly easily.
Saturday - eating more. Not off plan, but full meals and snacks and maybe some extra on plan foods
Sunday - light choices, no snacks
Monday - regular on plan choices and portions, 2 snacks
Tuesday - regular on plan choices, 1 snack
Wednesday - light choices, no snacks
Thursday - regular on plan choices, 2 snacks
Friday - regular on plan choices, 1 snack
