I am working through some of the Carnivore podcasts on Fast Keto, or Ketogenic Girl, linked above. Not my favorite interviewer but if interested in carnivore, she'll have to do. There is a Q & A with both Maria and Craig Emmerich, they use it as an elimination diet to determine foods that may cause your health problems. First, One month of only Beef & Salt! (Yikes ). Then a protocol to add other foods. One month is a loooong time.
