What Is the Carnivore Diet?

Should You Try the Carnivore Diet? These Experts Explain Why It's Not Healthy

As the Paleo, Whole30, and keto diets have exploded in popularity, it seems like more people are embracing meat than ever. But while animal meats of all kinds are staples in these popular diets, there's one new eating craze that takes it to the extreme: the carnivore diet.

Although the carnivore diet is a blanket term for a meat-based diet, an extreme version of this diet is just meat, salt, and sparkling water: no fruits, no veggies, no grains, and no carbs of any kind. Other versions include meat along with different types of animal products including cheese, eggs, and butter. Followers of this diet argue that meat has all the nutrients you need and eschewing all other food groups will heal your depression, fatigue, arthritis, and other autoimmune disease. They ascribe to the belief that vegetables aren't as healthy for us as we have been told and no, you don't need carbs to function. Not to mention, the carnivore diet is supposed to help you lose weight.

If this way of eating sounds bonkers, that's because it is. We tapped a registered dietitian and cardiologist to break down how the carnivore diet actually impacts your body and whether or not you should give it a shot. Spoiler alert: regular bowel movements aren't the only thing at risk.


Why You Need to Eat Other Food Groups

"While you would be able to survive eating only meat, I just don't think this diet is realistic or healthy," Jillian Kubala, MS, RD, told POPSUGAR. "Although there is research supporting the use of very low-carbohydrate diets, like the ketogenic diet, to treat certain diseases and promote weight loss, we don't yet have evidence that the carnivore diet is safe to follow long-term."

One major problem with the carnivore diet is that it eliminates complete food groups, including fruits and vegetables, and is void of one complete macronutrient group: carbohydrates.

"Other foods such as healthy fats, veggies, fruits, and complex carbs offer an abundance of important vitamins, minerals, and compounds that benefit health," Jillian explained. Unlike meat, fruits and veggies are loaded with fiber, which can help regulate your digestive system and keep you feeling fuller for longer. Plus, produce is packed with micronutrients and antioxidants that you don't get from meat alone.

Eating Too Much Meat Is Potentially Dangerous

Eating meat alone isn't just harmful for the lack of nutrients from other foods; it could potentially be dangerous. Too much red meat has been linked to colorectal cancer, and the World Health Organization has reported that when red meat is cooked at high temperatures, it becomes carcinogenic.

Cancer risk aside, eating too much meat and chasing it down with sparkling water, as one extreme version of this diet suggests, is inflammatory, explains board-certified cardiologist Luiza Petre, MD. Eating too much red and processed meat can also increase your risk of heart disease, she explained, especially since they are high in saturated fat and salt.

The amount of meat someone should eat in a day depends on their age, activity level, health status, weight, and nutritional needs. But in general, the American Heart Association (AHA) recommends the average person eat no more than six ounces of cooked lean meat, skinless chicken, and seafood per day, and four to five servings a week. The AHA also recommends limiting red meat along with saturated fat, sodium, sweets, and sugar-sweetened beverages.

Although you can technically survive on meat alone — and potentially lose weight if you are eating in a calorie deficit — it's not ideal for overall health. Instead, Dr. Petre recommends eating plenty of vegetables, and Jillian has a better approach to meeting your weight-loss goals:

"It's not necessary to cut out most food groups to drop pounds," she said. "I would recommend cutting out processed foods, added sugars, and simple carbohydrates and upping activity levels before trying out a restrictive diet like the carnivore diet."
