Hi, Abby, welcome!
I know you'll love the Beach...it's much less restrictive than Atkins, IMHO, but much healthier than our previous diets. It's a good thing!
The best way to get real results from Phase 1 is to do it with absolutely NO cheats! This means having a lot of SBD-safe food in the house. I recommend going to the grocery store today or as soon as possible and stocking up on things that will make this easier!
Also, check out the recipe forum...things like the Taco Bake, Stuffed Chicken, Almond Dijon Chicken, and Peanut Butter Cup really got most of us through Phase 1!
