What about a broader definition of what can constitute a paleolithic diet beyond individual lists of allowed and banned foods. I quite like Loren Cordain's ideas from some of his papers on this based on surviving hunter-gatherer groups. No doubt people will disagree about details. High, moderate and low are relative to the modern western diet.
Protein - High (19-35%)
Carbohydrate - Moderate (22-40%)
Total fat - Moderate (28-47%)
Total fibre - High
Vegetables and fruit - High
Nuts - Moderate
Salt - Low
Refined sugars - Low
Glycemic load - Low
Feel free to argue about the details but what do you think about the concept of a definition like this? How would you define it?

Combine Michael Pollan's rules (Eat real food; 5 or less ingredients; etc), with "don't eat things that cause allergic reactions in people - even if YOU don't have the reaction" (peanuts, wheat, dairy, etc), and add in a dash of "don't eat things you wouldn't eat raw" (grains, beans, etc).
Tada! Algorithmic definition of paleo
A definition should not focus on macro-nutrient content. If you want a very broad definition just go with "Eat real food, avoid things with poison in 'em." Then you can argue about what exactly is real food and what contains poison ^^
I personally like the numbers but most people who don't know what food is what will have a hard time figuring out their daily percentages so it ends up not being broad to the normal population.
im pretty sure we dont have a good understanding about what paleolithic people ate, even more so its intuitive that different people in different places ate vastly different things. paleo is more of an ideology than an instruction manual, and being so it is already broad in definition.
i would not define macros although i would say paleo as practiced tends to be moderate carb(mostly because of removed grains/sugars) with atleast a significant percentage of protein/fat.(because required for health) only real criteria for paleo seem to be(imo) avoidance or processed foods and if you are sensitive, modern foods, everything else is up for grabs.(personal preference/needs)
What we do: Eat as much fresh as practical, which is mostly either frozen fresh or fresh as in produce. Skip canned goods as much as possible. Avoid wheat, corn, soy based products when possible, reduce dairy intake. Typical meal around here for eve: Frozen fish, salmon, cod, catfish. Fresh combo salad: Bottled green olives, kale, onions, bell peppers, tomatoes, avocado, carrots, celery, cilantro, etc, sprinkled with Feta or Blue Cheese (note: takes very little of the pungent cheeses to satisfy and provide major added taste). Dressing: Roasted Walnut Oil, Avocado oil, Olive oil (all oils are mechanical,cold pressed extra virgin, unfiltered) drizzled on the salad then Lime or Lemon juice added direct to the salad. I also use the juice from the Olive jar as a salad dressing with some added oil.
