Ben Greenfield Changes His Mind on Keto, Carnivore, Statins, and More


Ben Greenfield shares his perspectives on several topics on health and fitness that he previously had a different viewpoint on. From the ketogenic diet to the carnivore diet, aspirin, and the use of ginger, this podcast aims to inform listeners about these topics and more from a new perspective.

Things That Have Changed Ben's Mind

  • Ketosis and Ketogenic Diet - While Ben previously believed that ketosis was beneficial for endurance-based workouts, he now believes that a carb-cycling approach is more beneficial. He used to follow a strict high-fat, low-carb diet but experienced long-term dysregulation of thyroid function. He advises against a strict ketogenic diet and suggests a more therapeutic and Mediterranean approach, such as avocados, avocado oil, olives, and fish.
  • Carnivore Diet - Ben discusses how he previously thought the carnivore diet was not sustainable and might not be the best long-term solution. However, he now believes that it can be a beneficial starting point for people who are obese or have diabetes and need to lose weight quickly. He recommends starting with a low-carb, high-protein diet and gradually introducing healthy fats and carbs.
  • Exercise and Plaque Build-up - Ben talks about how he previously thought that exercise was essential for preventing plaque build-up in the arteries. He now believes that plaque build-up starts with inflammation and that diet has a significant impact on preventing it.
  • Plasma Velocity Measurement - Ben discusses how he previously thought that measuring plasma velocity was essential for heart health. However, he now believes that measuring the speed of blood flow is not necessary, as other methods, such as monitoring blood pressure and cholesterol levels, are more accurate indicators of heart health.
  • The Use of Aspirin - Ben used to recommend taking aspirin to prevent heart attacks and strokes, but he now believes that it is not as effective as previously thought. He suggests that a holistic approach to heart health, including diet, exercise, and stress management, is more beneficial than relying on a single medication.
  • The Benefits of Ginger - Ben discusses how he used to believe that ginger had limited uses, but now believes that it has many benefits, including aiding digestion and reducing inflammation.
  • The Impact of Viagra on Heart Health - Ben used to believe that Viagra could lead to increased risk of heart attacks, but now believes that there is insufficient evidence to support this claim.
  • Over-Prescriptions of Statins - Ben states that statins are often over-prescribed and that lifestyle and dietary changes should be the first approach to improving cholesterol levels.
  • Ad for Ben's House - Ben shares an ad for his upcoming house listing, which includes a gym, juice bar, sauna, and grounds for exercising animals.

Analyzing the Heart Health Snippet

  • Cold Exposure - Ben believes that cold exposure is beneficial for health and that taking cold showers or doing ice baths is worthwhile.
  • THC - Ben previously believed that THC was harmful to health, but now believes that it has many benefits, including reducing nausea and increasing appetite. He suggests that THC is not as dangerous as previously thought and that it has potential therapeutic benefits.
  • Sleep Hygiene - Ben discusses the importance of optimizing sleep hygiene and how it has a significant impact on overall health. He mentions using blue-light-blocking glasses and prioritizing sleep.
  • The Importance of Being Moderate - Ben stresses the importance of finding a healthy medium and not being too extreme in any direction when it comes to health and fitness.
  • End of Podcast - Ben reminds listeners to check the shownotes for more information and sign up for his newsletter.
