Doctor Loses 70 Pounds of Weight on Carnivore Diet: “Americans Have Been Misled About Nutrition,” He Says
The positive results reported respond more to personal experiences than to clinical evidence.
The International Food Information Council survey reveals that 70% of Americans prioritize protein consumption, a significant increase from 62% in 2021. This shift in dietary perceptions indicates a growing inclination toward meat-rich diets, especially in the context of personal health.
Along these lines, Dr. Ken Berry, a doctor in Tennessee, has become a central figure in the promotion of carnivore diets. His personal testimony about losing 70 pounds of weight (approximately 32 kilos) and improving his health has resonated with many followers, especially at events like Meatstock 2026, where the benefits of these diets are discussed, reports Fox News Digital.
“I live on beef, butter, bacon and eggs,” Berry said.
Meatstock attendees share success stories related to the carnivore diet, claiming significant improvements in their health and well-being. These testimonies reflect a phenomenon that is attracting increasing attention.
Debate between nutritional experts
While some experts, like Dr. Berry, defend the carnivore diet, others are critical, like Harvard's Walter Willett, warning about the lack of essential nutrients and the potential long-term risks associated with its practice. Health specialists warn that excessive consumption of red meat significantly increases the risk of cardiovascular diseases, colorectal cancer and type 2 diabetes.
A Harvard study also reveals that a daily serving of unprocessed red meat increases the risk of cardiovascular mortality by 13%; and the processed 20%.
Dr. Berry points out that many nutritional studies may be biased and that concerns about red meat and sausages are overblown. Admit that whole grains and fruit juices are good for your health, that they will keep you alive, but they will not “optimize your health.”
He adds that popular whole foods, like bread and oatmeal, are also “almost uniformly inflammatory for most people.” While the starch present in legumes, beans and other foods commonly considered healthy causes insulin spikes in people.
"We have not changed genetically as a species for 100,000 years. Therefore, our diet should be predominantly meat, or exclusively meat," he asserts.
However, organizations such as the World Health Organization (WHO) remain alert about the risks associated with the consumption of processed meat.
The WHO advises not to exceed 500 g of red meat per week.
Future perspectives
The continued growth in popularity of carnivore diets reflects a significant shift in perceptions about health and nutrition.
As more Americans seek protein alternatives, the debate over the quality and quantity of protein consumed will continue to be a relevant topic in the public conversation about diet.
There is no strong evidence that this diet is safe or beneficial in the long term. The scientific community warns that eliminating fruits, vegetables and fiber can trigger problems for the heart, brain and digestive system. Eliminating entire food groups is considered not recommended.
The positive results reported respond more to personal experiences than to clinical evidence, and the long-term impact on health remains not well documented in clinical studies.
