Dr Naiman has not suggested PP over real whole foods but understands for his patients with time constraints in the morning, women who just cannot eat more meat, etc , it is a "cheat code". He is a crusader for "not all processed food is evil" Butter is processed, whey processing is not much different.

I started with his one meme, and a limit of 50 net carbs…and I had to work up to that many carbs. But it was very similar to the New Atkins approach where I started. Marty Kendall's macro class would be better for anyone sensitive to FODmaps…starts from where you are now and adjusts slowly (if possible).
