I don’t find it difficult, but I’m not that strict. I follow Mark Sisson’s “primal” version of the paleolithic diet, which allows dark chocolate, coffee, tea, and some wine and beer. I also eat some dairy products, but I try to stick to the “ a2 ” casein varieties of dairy (milk and cheese from goats, sheep, and Guernsey cows). Legumes (beans, peas, and peanuts) aren’t included in the paleo diet, but the lectins can be mostly soaked and cooked out, and they’re packed with antioxidants and other nutrients. I stay away from soy (which can mess with hormones) and red kidney beans (packed with toxic lectins), but I sometimes eat green beans, peas, pinto beans, and peanuts.
