Vegetarians can follow the Ideal Protein Weight Loss Protocol and can consume eggs, fish or tofu during their evening meal for their whole protein. As an alternative, vegetarians can have 2 Ideal Protein foods for dinner in replacement of their whole protein. Ensure you review the ingredient list on all boxes before purchasing them. Strict vegans, who do not consume any animal proteins and animal by-products, such as dairy products, honey and so on, do not qualify to follow the Ideal Protein Weight Loss Protocol due to the many dietary restrictions.
