What got me started 5 years ago was me offering a dessert to my oldest adult daughter and she said "we can't, we are doing keto".

I said "what the hell is keto".

That lead me to read Keto Reset Diet by Mark Sisson. Which lead me to Primal Endurance...then Primal Blueprint. After reading that, I became a Primal Health Coach. What they said made so much sense, and I'd suggest skipping straight to Primal Blueprint.

Of course, then I started the firehose on a lot of the thought leaders in the space: Mark Sisson, Jason Fung, Robb Wolf, Ken Berry...Paul Saladino was an up-and-comer - really in your face about carnivore like Shawn Baker - and I appreciated the greater detail he provided in his podcasts. He and Baker got me interested in going full carnivore.

Baker has remained a carnivore, but Saladino has moved to more "Animal Based". I'm anti-FB, but I do still use Instagram to follow some of these folks...and share health and wellness as well as tennis content. Saladino has some nice video shorts on Instagram where he packs a lot of knowledge or dispels myths. He's worth the follow over there (or at least search his content). He also wrote the Carnivore Code.

- Keto is pretty strict about ketosis...will keep you to 20-30g of carbs/day.

- Paleo is pretty much whole foods that your paleo ancestors would eat...so no grains or anything farmed...but meat, seeds, nuts, berries, etc.

- Primal is a more relaxed Paleo in my opinion

- Carnivore...from the strictest standpoint...is meat and salt! I also think it is the BEST elimination diet. Go carnivore for 2-4 weeks, then slowly introduce 1-2 foods and judge how you feel/sleep/triggers for inflammation or auto-immune issues. Rinse...repeat.
