Unless you’ve been living under a rock for the past several years, you’ve probably heard someone touting the health benefits of the paleo diet. (Maybe it was one of the many celebrities who have given it props, like LeBron James, Kobe Bryant, Matthew McConaughey, Megan Fox, and Uma Thurman?) But before you start eating like a Flintstone, here’s what you need to know about the enduring caveman-inspired health craze.
What Is the Paleo Diet?
The Paleolithic Diet—also known as the paleo or caveman diet—is a meat-centric, low-carbohydrate diet that eschews grains, beans, dairy products, and refined sugars in favor of meat, fruit, and vegetables. It’s based around the concept that modern humans have been unable to adapt fast enough to handle some of the foods that have been created since the advent of agriculture, and that we should be eating a diet as close as possible to that of our caveman ancestors who actually lived during the Paleolithic era.
While it seems like a pretty modern phenomenon, it’s actually been around since the 1970s, when gastroenterologist Walter Voegtlin wrote “The Stone Age Diet” (which was self-published, and so is pretty difficult to find these days); it gained ground when Loren Cordain wrote his book “The Paleo Diet” (a term he subsequently trademarked) in 2002. But paleo didn’t become mainstream until the last several years: we first wrote about it building traction in 2011 when a paleo-themed restaurant opened in Germany. Since then, paleo’s only gotten more popular—take the success of Nom Nom Paleo (created by Michelle Tam, who we interviewed in 2017) for just one prominent example.

Why Go Paleo?
Eating like a caveman emphasizes eating whole foods that are absent of gluten and dairy, both of which have been known to trigger allergic reactions. And because the diet provides few carbohydrates, it’s been known to bring on quick weight loss; with drastically fewer carbs, the body winds up burning stored fat instead. But in addition to aiding in weight loss and maintenance, according to paleo advocates, the diet prevents so-called diseases of civilization such as Type 2 diabetes and heart disease. In addition, many swear by its ability to reverse autoimmune diseases and diabetes, and even clear up skin.
Still, many studies have been inconclusive as to whether the diet will help you lose weight in the long run, or whether it has proven cardiovascular benefits. It’s also not without its naysayers. Michael Pollan, for one, was quick to say proponents of the diet were “blowing smoke.” Some scientists counter that there’s evidence Paleolithic beings did eat grains, and that they ate varied diets; still other critics cite The China Study, a large study that examined the correlation between animal products and chronic illnesses. If you want a personal opinion, check out the aformentioned interview with Michelle Tam, the so-called Queen of Paleo.
What’s Not Allowed on the Paleo Diet?
Just about all grains, such as wheat, corn, rice, barley, quinoa, and amaranth, are off-limits. So are beans and legumes like lentils and peanuts, since they weren’t part of our ancestral diet. Dairy, alcohol, overly salty foods, and added sugar aren’t allowed. Corn syrup, artificial colorings, preservatives, and flavorings are prohibited because they’re processed; for that reason, so are most vegetable oils. Say bye-bye to packaged snacks and convenience foods too—or as PaleoLeap puts it, “As a rule of thumb, if it’s in a box, don’t eat it.”
It should be noted that eating paleo is not the same as eating gluten-free (although it does have much in common with the Whole30). While this diet is naturally gluten-free, a gluten-free diet is not automatically paleo; gluten-free grains like rice and quinoa are prohibited on the paleo diet.
OK, So What Can You Eat on Paleo?
Paleo eating revolves around well-raised meat, fish, poultry, eggs, lots of fruits and vegetables, and nuts. Expect to eat a lot of animal protein; note that this can get expensive, and if you’re a vegan or vegetarian, this diet probably isn’t for you.

You’ll also eat lots of non-starchy vegetables, although starchy tubers with lower glycemic levels, like sweet potatoes and yams, are OK to eat. Expect to ingest a whole lot of cauliflower, particularly in the form of cauliflower rice and cauliflower pizza crust.
Because most vegetable oils are off-limits, animal fats are popular; so are lesser-processed oils like olive oil and coconut oil. For any recipes that might traditionally call for flour, expect substitutions like almond meal, almond flour, or coconut flour.
While it’s not at all in keeping with the spirit of the diet, it’s technically possible to find some paleo fast food options, but in general, it’s tough to find good paleo-friendly options while dining out. Luckily, there are plenty of make-at-home menu options, and within the stated limitations, you can eat whatever you want, whenever you want.
Is Paleo the Same as Keto?
keto diets do have a lot in common, most importantly an emphasis on whole, nutritionally dense, fresh foods, but they’re not identical. In general, keto puts a higher emphasis on cutting carbs and tends to be higher in fat than paleo. To do keto correctly, you need to monitor macros and calories pretty strictly, but paleo is more about simply focusing on unprocessed ingredients that fall within the parameters of a pre-civilization style of eating (call it a hunter-gatherer diet if that helps). On keto, you’re a lot more limited; with paleo, less so. Neither diet encourages consuming much sugar, for instance, but if you’re paleo, you’re free to use moderate amounts of raw honey or maple syrup (among other natural sweeteners) since they’re both whole, minimally processed foods that have been around for eons—whereas keto says no to both honey and maple syrup because they’re high in carbs. Instead, you’d look to a sugar substitute like Swerve or stevia if you were going keto. (Honestly, there’s a lot to be said for just practicing mindful eating!)No. The paleo and
