Mark Hyman
Mark Adam Hyman is an American physician and author.
Hyman endorsed a low-carbohydrate high-fat diet in his books Eat Fat Get Thin and The Eat Fat, Get Thin Cookbook, published in 2016. In these books, Hyman disputes commonly held ideas about consuming dietary fat. He says that saturated fat does not cause heart disease and obesity; processed carbohydrates do. Hyman recommends his readers transition to a pegan diet.
Hyman promoted the pegan diet, a plant-rich diet that combines principles of the paleo and vegan diets. The pegan diet is gluten-free and encourages consumption of nonstarchy vegetables with grass-fed organic meats and low-mercury fish. The diet consists of 75% plant foods and limits fruits to low-glycemic berries. The pegan diet opposes refined sugar and foods that can spike insulin production. The diet also opposes cow’s milk but is not dairy free. Hyman allows the occasional organic goat or sheep milk, yogurt, kefir, grass-fed butter, ghee or cheese. Hyman has stated that the pegan diet can be defined by one simple rule: “If God made it, eat it; if man made it, leave it.”
Hyman first wrote about the pegan diet in 2014 and outlined it in his book Food: What the Heck Should I Eat?, published in 2018.

Discover the benefits of “eating your medicine” with twelve-time New York Times bestselling author Mark Hyman, MD’s unique Pegan diet, “a masterpiece on food and health” (William Li, author of Eat to Beat Disease).
What do you get when you combine the best of paleo with the best of vegan? Pegan! For decades, the diet wars have pitted advocates for the low-carb, high-fat paleo diet against advocates of the exclusively plant-based vegan diet and dozens of other diets leaving most of us bewildered and confused. For those of us on the sidelines, trying to figure out which approach is best has been nearly impossible—both extreme diets have unique benefits and drawbacks. But how can it be, we’ve asked desperately, that our only options are bacon and butter three times a day or endless kale salads? How do we eat to reverse disease and optimize health, longevity, and performance? How do we eat to reverse climate change? There must be a better way!
Fortunately, there is. With The Pegan Diet’s food-is-medicine approach, Mark Hyman explains how to:
Combine the best aspects of the paleo diet (good fats, limited refined carbs, limited sugar) with the vegan diet (lots and lots of fresh, healthy veggies)
Create a delicious diet that is not only good for your brain and your body, but also good for the planet.
