What Does Dr. Anthony Chaffee Eat on His Carnivore Diet?

5 min read

According to a March 2025 interview, Dr. Anthony Chaffee's diet consists entirely of fatty meat, water, and salt, with an emphasis on red meat. This strict approach is a cornerstone of his philosophy, which answers the common question: what does Dr. Anthony Chaffee eat?

Quick Summary

Dr. Anthony Chaffee follows a zero-carb carnivore diet based on fatty cuts of meat, some organ meat, and animal fats. He typically consumes one meal per day and avoids all plant-based foods, including coffee, tea, and spices.

Key Points

  • Fat is Fuel: Dr. Chaffee's diet emphasizes high fat intake, with around 70% of his calories coming from animal fats.

  • Meat, Salt, and Water: The diet is extremely restrictive, consisting almost exclusively of meat, salt, and water, with no plants, sugar, or caffeine.

  • Single Meal Approach: He often consumes only one large, satiating meal per day, relying on the high fat and protein content to sustain him.

  • Focus on Red Meat: His staples are fatty cuts of red meat, such as ribeye, scotch fillets, and lamb chops.

  • No Plant-Based Foods: All fruits, vegetables, grains, nuts, and seeds are eliminated due to his belief in their potential toxicity.

The Foundational Principles of Dr. Chaffee's Diet

Dr. Anthony Chaffee's dietary approach is more than just a diet; he views it as a medical intervention based on his research and personal experience. His conviction stems from the belief that most chronic diseases are caused by modern plant-based foods and that an ancestral, all-meat diet is optimal for human health. The core of his eating habits can be summarized by a few key principles:

  • Fat is Fuel: A significant portion of his calories, approximately 70%, comes from animal fats. This high-fat content is crucial for energy in the absence of carbohydrates. When following this diet, he consumes fatty cuts of meat and adds extra animal fat or butter.
  • Meat and Water Only: The diet is extremely restrictive. He consumes meat and drinks water, with salt being the only other accepted element.
  • One Meal a Day (OMAD): Dr. Chaffee often practices intermittent fasting by eating only one large meal per day. The high satiety from fat and protein helps him feel full for extended periods, eliminating the need for constant eating.
  • No Plant-Based Products: A strict prohibition is placed on all plant foods, including vegetables, fruits, nuts, seeds, spices, coffee, and tea. He argues that many plant compounds are toxic to humans.
  • Minimal Dairy: While some variations of the carnivore diet permit dairy, Dr. Chaffee's approach is more restrictive. Some minor, occasional exceptions for high-quality, full-fat dairy like butter or hard cheese might exist, but it is not a staple.

A Closer Look at Dr. Chaffee's Typical Meal Choices

Dr. Chaffee’s daily intake is simple yet nutrient-dense. The focus is on quality and fat content. His staples include:

  • Fatty Cuts of Red Meat: His preference for ribeye and scotch fillets is well-documented. These cuts provide a high-fat-to-protein ratio, which aligns with his goal of deriving most calories from fat.
  • Lamb Chops: He enjoys lamb midloin chops specifically for their high fat content.
  • Added Fat: To ensure he meets his fat intake goals, he frequently adds grass-fed butter to his steaks or fries up small cubes of pure beef fat alongside his meat.
  • Organ Meats: From time to time, he includes bone marrow in his diet for its richness in nutrients. Other proponents of the carnivore diet also highlight organ meats like liver for their density of vitamins and minerals.
  • Bone Broth: Some followers of his method include bone broth for additional minerals and collagen, though Dr. Chaffee primarily focuses on the solid meat and fat.

For most people, a diet this restrictive can be challenging. For Dr. Chaffee, however, the elimination of all potential inflammatory plant toxins and the stability provided by fat-based energy are the primary drivers. His regimen is designed for maximum metabolic efficiency and minimal gut irritation.

The Carnivore Diet vs. Ketogenic Diet: A Comparison

Feature Dr. Anthony Chaffee's Carnivore Diet Standard Ketogenic Diet
Carbohydrates Zero-carb; all plant matter eliminated. Very low-carb (typically <50g/day); carbs from non-starchy vegetables, nuts, and seeds are permitted.
Fiber No dietary fiber, as it is found only in plants. Contains low amounts of fiber from non-starchy vegetables.
Protein Moderate to high, from muscle and organ meats. Moderate; excessive protein can be converted to glucose and disrupt ketosis.
Fat High; primary energy source from animal fats. High; primary energy source from animal and plant fats (avocado, olive oil, nuts).
Food Variety Extremely limited, only animal products. More diverse, including meat, dairy, eggs, fish, and some plant-based foods.
Controversy Highly controversial due to nutrient concerns and restriction. Well-researched, but still debated for long-term health effects.

The Rationale and Potential Side Effects

Dr. Chaffee's perspective is that humans evolved as carnivores and that plant foods introduce toxins and inflammatory agents that harm our health. He argues that by removing all plant matter, the body can heal itself from conditions like autoimmune issues and diabetes. The ketogenic state induced by the carnivore diet is claimed to have numerous benefits, including fat loss, increased mental clarity, and reduced inflammation.

However, this diet is not without potential downsides, as acknowledged by many nutrition experts. Side effects can include:

  • Nutrient Deficiencies: The complete elimination of fruits and vegetables can lead to a lack of certain vitamins, minerals, and antioxidants typically found in plant foods. While Chaffee believes meat provides sufficient nutrients, this is a point of contention among nutritionists.
  • Lack of Fiber: With no plant fiber, constipation is a common initial side effect for those starting the diet. Dr. Chaffee advises increasing fat intake to remedy this.
  • High Saturated Fat and Sodium: The heavy consumption of red and processed meats, often rich in fat and sodium, raises concerns about cardiovascular health for some individuals.
  • Highly Restrictive: The limited food choices make this diet challenging to sustain long-term for many people.

Conclusion: A Controversial but Simple Approach

Dr. Anthony Chaffee's diet is a very specific and strict form of the carnivore diet, focusing on fatty red meat and animal fats. He avoids all plant foods, practices intermittent fasting, and emphasizes fat as the primary energy source. While he cites personal benefits and research supporting his species-appropriate diet theory, it remains highly controversial and is not recommended by mainstream health organizations. Individuals considering such a restrictive diet should do their own research, listen to their body, and ideally consult a healthcare professional.

Dr. Chaffee's Typical Eating Pattern

Breakfast: Typically skips breakfast, opting for water until his single large meal. Lunch: Not applicable on his typical one-meal-a-day schedule. Dinner: A large fatty red meat meal, such as ribeye steak or scotch fillets, often cooked with added beef fat or butter. Occasional Additions: Bone marrow and fatty lamb chops are included periodically.

Lifestyle Integration

Beyond just the food itself, Dr. Chaffee's diet is part of a broader lifestyle. He often discusses the benefits he's experienced, such as improved energy levels, better muscle development, and enhanced overall health after transitioning fully to this approach.

For him, it’s not just a way to eat but a way to live that has significantly improved his health and athletic performance.
