You are in the right place as far as day 1 before your package arrives. Take a look at the support groups (this forum, and Facebook too) so you are familiar with the questions that are typically asked when you first begin. Check out the recipes, and the menu plans (located in the member store at the bottom) It gives you a shopping list too if you want to follow it exactly. Otherwise you will need to wait until your booklet arrives in the mail so that you can fully understand how to go through the program and what is approved (foods).
Hope this helps , and welcome!
