I'm just beginning to read about the SS. When I did FF phase 1 a few years ago, the SS didn't exist, so I'm excited for this easier option!
I have yet to read more about it, but I'm wondering what a vegetarian is allowed to do for extra protein? I think on the original FF, ALG discouraged much soy and it was suggested to do an extra serving of whey per day - is that what I would do for the SS, as well - an extra serving of the Body Protein?
Also, besides deriving from different sources, how does the Body Protein differ from the Whey Protein? How is it better for weight loss than whey? Is whey better for other things?
Lastly, for purposes later, is the whey protein casein free?
