can the community spitball a "beginner's" guide to the common nutrition ideas of PHD, robb wolf, chris kresser, jack kruse, kurt harris and ray peat? (i also think someone like david wolfe might be an expert, only because he arrived at health via a totally different methodology and still produced results)
i think for starters they all recommend no grains (except white rice) and legumes and Low PUFA, and everyone agrees that gut health is the most important thing.
Once you have those down, you can tinker w/ macro ratio's. In terms of carbs, you will cut back on a lot of processed carbs, and extra sugar by sticking to mostly whole clean food. No reason you HAVE to be very low carb to be paleo.
Hopefully that helps.
I think all of them think some amount of animal protein is necessary. Ray Peat recommends gelatin, and Bone Broth is widely recommended.
Stress management is in common, but ray peat is probably an outlier in the recommendations.
That seems to be the ground common to most within the Ancestral/Paleo camp.
Some of the various "experts" don't have problems with nuts (PUFA), some are okay with white rice (a grain), a few like Kresser have questioned whether non-peanut non-soy legumes are that big of a deal, and I am not sure everybody would say gut-health is most important (some might say brain health or liver health or whatever, or some might say inflammation in general is most important.)
I don't think anybody is fan of man-made trans-fats or high-fructose corn syrup either, but that is kind of a given.
