Fat Smash Diet Recipes - new to fat smash

Can anyone answer these questions for phase I:

Can I eat veggie burgers that I buy in the supermarket?
Can I eat sweet potatoes on phase I?
Can I eat Non Fat Yogurt that is flavored?

Please advise and thanks for the help.

1. Veggie burgers: check the ingredients list. There are a lot that contain cheese and dairy byproducts.
2. Sweet potatoes: yes
3. Per the Q&A with Dr Ian (writer of the FS diet), you can in moderation (you only get 12 ounces per day anyhow) but plain yogurt is what is recommended.
