Sarah Ballantyne is not a doctor. I guess there is a difference between reading a lot of researches and treating patients. Most doctors are I see/notice do things that are right against 'The Paleo Approach' For example, not to be on AIP for more than 2 months. Not eating safe starches ie Keto helps kill gut bugs, prescrbing colostrum to patients. Going on AIP has further downgraded my health. I traded skin issues for extreme fatigue, brain fog, zero energy to even stand-up etc.
