Both Dr. Ted Naiman and Marty Kendall are not fans of the carnivore diet. It has its place, there have been success stories for various health conditions, but long term, there are concerns about micronutrient deficiencies. I have heard Dr Naiman express these concerns in various podcasts.
Marty‘s take on one of the carnivore diets is: https://optimisingnutrition.com/carnivore-diet/

Ps: back in 2019 when you started low carb, you mentioned using the food graphics at Diet Doctor. Dr. Naiman is now consulting for Diet Doctor on this change to higher protein and higher satiety foods. So in answer to your question about tracking, you could also use those high-protein food lists. I posted some of them in my success story and the comments.

Another good interview with Dr Naiman on DD. At minute 40, how to improve your diet in slow incremental steps: https://www.dietdoctor.com/video/po...thy-weight-loss
