For years, the mantra of healthy eating has revolved around cutting back on red meat and loading up on veggies. Meanwhile, the rise of veganism has almost taken on a cult-like status.
But there’s a twist in the tale for meat lovers: the carnivore diet is making waves again! Advocates of this all-meat regimen, which ditches everything plant-based, claim they’ve never felt better.
Unlike popular diets like Keto and Paleo, the carnivore diet takes it a step further by excluding all plant foods, focusing solely on meat and animal products. This trend has been gaining momentum on social media, championed by high-profile figures like Joe Rogan.
Followers of the carnivore diet consume primarily animal products—no grains, vegetables, processed foods, or added sugars. Some include dairy, honey, or fruit, but many stick strictly to meat, salt, and water.
Despite the buzz, there’s little scientific research backing the carnivore diet. However, proponents report weight loss, improved chronic health conditions, and increased energy, according to a 2021 survey.
The diet has sparked controversy, with experts warning it could raise cholesterol levels and deprive the body of essential plant-based nutrients like fiber and polyphenols, potentially increasing the risk of long-term illnesses like cancer.
“The carnivore diet isn’t what I would recommend for most people,” says nutrition expert Layne Norton. “While meat can be part of a healthy diet, completely cutting out fruits, vegetables, and fiber is risky.”
Supporters argue that a meat-heavy diet is a nutrient-rich alternative to the refined grains and sugars common in the American diet. However, some nutrition researchers remain skeptical, pointing out that personal success stories are no substitute for rigorous scientific evidence.
While some carnivore dieters report improvements in mental and neurological health, as well as relief from autoimmune symptoms, Norton cautions that these claims lack scientific backing. He suggests that the benefits may be due to factors other than the meat-only diet itself.
One potential explanation is that the carnivore diet is nearly carb-free, which could help stabilize blood sugar and improve mood and cognitive function. Additionally, cutting out processed foods might contribute to these positive effects.
Shawn Baker, a prominent carnivore advocate and former orthopedic surgeon, notes that it’s unclear whether the benefits come from eating more meat or less of other foods. Both factors may play a role, depending on what the diet replaces.
Norton advises caution when considering the carnivore diet. “The vast majority of evidence indicates that fiber is beneficial, and meat, while a great source of protein, shouldn’t be the only food in your diet.”
For now, the debate over the carnivore diet remains largely anecdotal, as no clinical trials have definitively proven its health impacts. While long-term studies on dietary effects are challenging, most existing knowledge is based on observational evidence.
Experts in nutrition and cardiology caution that diets high in animal fats and low in plant nutrients may pose long-term health risks, including heart disease, cancer, and elevated LDL cholesterol.
“We don’t have evidence to suggest this is a good idea,” says Stanford professor John Ioannidis. “But we do have indirect evidence that it might not be.”
