Dr. Ken Berry, a physician based in rural Tennessee, has become a prominent advocate for the carnivore diet, a meat-based eating plan he credits with his own 70-pound weight loss and reversal of prediabetes. Speaking at Meatstock 2026, an annual gathering for enthusiasts of carnivore and ketogenic diets, Berry emphasized that Americans have been ‘misled and misfed’ when it comes to nutrition.

Growing Interest in Protein

According to the International Food Information Council’s 2025 survey, a majority of Americans (70%) are prioritizing protein consumption, a significant increase from 62% in 2021. This shift in dietary focus aligns with Berry’s message that meat-based diets can lead to improved health outcomes. He shared numerous testimonials from individuals who have experienced benefits such as reduced inflammation and improved liver health.

Debate Among Nutrition Experts

While Berry and others at Meatstock advocate for a diet rich in meat, eggs, and fish, some nutrition experts remain skeptical. Critics argue that such diets may lack essential nutrients found in fruits and vegetables and could contribute to climate change. Walter Willett, a professor of nutrition at Harvard, has expressed concerns about the absence of fiber and other nutrients in a purely carnivorous diet.

Challenging Conventional Wisdom

Berry challenges common nutritional beliefs, suggesting that whole grains and fruit juices, often considered healthy, may not optimize health. He argues that many nutrition studies are influenced by conflicts of interest and that concerns about red and processed meats are overstated. Despite criticism, Berry’s keynote speech has attracted significant attention online, reflecting a growing curiosity about alternative dietary approaches.

Affordability and Accessibility

Berry also addresses concerns about the affordability of a meat-based diet, noting that it can be cost-effective if consumers choose less expensive cuts and focus on ingredients like meat, salt, and spices. He suggests that processed meats like bacon and hot dogs can be part of a healthy diet if selected carefully.

As the debate over optimal nutrition continues, Berry’s advocacy for the carnivore diet highlights a broader trend of Americans seeking new ways to improve their health through dietary changes.
