The paleo diet (also nicknamed the caveman diet, primal diet, Stone Age diet, and hunter-gatherer diet) is hugely popular these days, and goes by one simple question: What would a caveman eat? Here, we explain what the paleo diet involves, its pros and cons, and, ultimately, what a modern person needs to know to decide whether or not to take the paleo diet plunge.
While Paleo followers won't be found throwing spears or wearing lion furs, the "Paleo way" does go beyond the foods we eat by emphasizing healthy lifestyle habits such as getting enough sleep, stress reduction, sun exposure, exercise, and avoiding harmful substances.
