So, as far as I can tell, Paleo eating essentially means not eating grains/legumes or sugar or vegetable oil, and not eating a no-fat diet. That's about the crux of it.
But then there are other styles/fads that people tend to be fans of: high fat, fish oil, sweet potatoes, coconut everything, etc. I'm not saying these are equal, these are just common elements of a paleo diet, none of which are required to avoid toxic foods.
And then there are these problems that keep popping up on PH:
Binge eating: This appears to be a major problem. This could be a self-selection issue (people who used to severely restrict often end up with BED, so maybe they also tend to be the types who obsess about their diets on an internet forum).
Crazy high cholesterol: Seriously, I know that it's overall cholesterol that counts, but some of the numbers people report really are frightening and new (i.e., people didn't have ridiculously high LDL before but now do).
Food intolerances: it seems like more people are developing more food intolerances on a "paleo diet" than they had before (people saying, e.g., I've eaten eggs my whole life and now suddenly I can't; I had a bowl of cereal for breakfast every day for 20 years, I cut out grains, but now suddenly 1/2 a glass of milk makes me sick, etc.).
Weight gain: some (generally normal weight or slightly overweight) people appear to be doing everything right, and are still gaining weight compared to their diet before.
But given that straight-up don't eat poison paleo is so very benign, what do we think the common mistakes are that cause people to suddenly develop these problems that they didn't have before? Some people might say it's an adjustment issue, but a lot of people reporting these problems appear to have been eating pretty solidly "paleo" for months.
I doubt that eating English muffins with margarine somehow protected people from these ailments, so it must be something else that we're all commonly doing that maybe we shouldn't. I have my theories (just because some meat/fat is good doesn't mean tons of meat/fat is better, people tend to OD on "safe foods" which can cause intolerances, it's harder to rely on calorie counts when you don't eat from a box, etc.), but I'd like to hear everyone else's thoughts.
What common missteps on a paleo diet tend to lead to some of the common seemingly paleo-diet-related ailments?
