Peter Attia MD - What does science tell us about the carnivore diet? | Stephan Guyenet and Peter Attia
The discussion centers around the carnivore diet, highlighting its effectiveness in weight loss due to its low carbohydrate and high protein content. The diet's lack of variety and exclusion of processed foods contribute to its slimming effects. However, there is a lack of empirical data supporting its long-term health impacts, particularly concerning elevated LDL cholesterol levels, which could increase cardiovascular risk. The conversation also touches on the ideological nature of dietary choices, comparing the carnivore diet's rigid adherence to low-carb principles with similar tendencies in the vegan community. The importance of balancing diet benefits with potential health risks is emphasized, suggesting that modern medicine can address issues like high LDL while maintaining dietary preferences.
Key Points:
- Carnivore diet leads to weight loss due to low carbs and high protein.
- Lack of variety and exclusion of processed foods contribute to weight loss.
- No strong empirical evidence on long-term health impacts, especially LDL cholesterol.
- Dietary ideologies can lead to ignoring potential health risks.
- Modern medicine can treat high LDL while maintaining dietary preferences.

1. 📚 Exploring the Carnivore Diet: Anecdotes and Insights
- The carnivore diet leads to weight loss as reported by all individuals consulted, but there is no solid scientific data like randomized control trials to support these claims.
- The diet's effectiveness in weight loss might be due to its zero or very low carbohydrate content, which is more likely to be slimming compared to diets high in both carbohydrates and fats.
- The lack of carbohydrates aligns the diet with the extreme ends of the fat-to-carbohydrate ratio, which is generally more effective for weight loss than balanced or high-carb diets.
- The diet may lead to reduced calorie intake because individuals might find it hard to consume enough calories due to the restrictive nature of the diet.
- Potential health risks include nutritional deficiencies due to lack of variety and essential nutrients normally obtained from plant-based foods.
- Adherents may experience increased cholesterol levels, which could pose cardiovascular risks.
- The diet excludes all plant-based foods, which can lead to deficiencies in fiber, essential vitamins, and minerals necessary for overall health.
- Reported benefits also include reduced inflammation and improved mental clarity, which some individuals attribute to the exclusion of carbohydrates.

3. 🌿 Evaluating Plant-Based Claims: Evidence vs. Ideology
- Certain plants, like spinach, contain oxalates that can lead to kidney stones, while cabbage contains glucosinolates that may contribute to Type 2 diabetes, emphasizing the need for awareness of potential risks in plant-based foods.
- Improperly prepared kidney beans can be toxic due to high lectin levels, illustrating the critical role of proper preparation in plant-based diets.
- While some dietary beliefs strictly favor animal products, a balanced evaluation based on empirical outcomes and cost-benefit analysis is crucial for assessing the healthiness of foods.
- The evaluation of plant-based foods should consider both their nutritional benefits and potential risks, supported by scientific evidence rather than ideological adherence.
4. 🔬 Biochemical Shifts in Carnivore Diets: Health Implications
- Carnivore diets induce a ketogenic state due to extremely low carbohydrate intake, altering metabolism significantly.
- A survey of around 2,000 individuals on carnivore diets indicated a notable decrease in triglyceride levels, but a significant increase in LDL cholesterol.
- Participants in the survey, primarily sourced through social media, reported changes in LDL particle count, though the study lacks rigorous scientific validation.
- Further investigation is needed to conclusively understand the long-term health implications of these biochemical shifts, particularly the rise in LDL cholesterol.
5. 💊 Balancing Diet and Health: Addressing Elevated LDL
- Paul Saladino's LDL cholesterol level is 533 mg/dL, indicating extremely high levels of LDL, which can be a cardiovascular risk. This highlights the need for individuals with similar profiles to monitor and manage their health proactively.
- Survey data suggests a mean increase of 30-40 mg/dL in LDL cholesterol for some individuals following certain diets, though results vary significantly from one person to another. This variance underscores the importance of personalized dietary monitoring.
- While some individuals like Sean Baker maintain normal lipid levels on similar diets, others experience significant increases, raising concerns about cardiovascular risk and the need for individualized health assessments.
- There is a tendency within certain diet communities to view high LDL as a non-issue or even a positive outcome, despite strong cardiovascular risks associated with elevated levels. It is crucial for individuals to critically assess these perspectives and make informed health decisions.
- Elevated ApoB, associated with high LDL levels, is considered highly treatable through modern medicine. This allows individuals to maintain their dietary preferences while effectively managing cardiovascular risk, emphasizing the role of medical interventions.
- The ideology within both carnivore and restrictive plant-based diet communities can prevent individuals from addressing potential health risks associated with their dietary choices. It's important for individuals to remain open to adjusting their dietary practices to improve health outcomes.
6. 🤝 Diet Ideologies: Bridging Carnivore and Vegan Perspectives
- Diet ideologies such as veganism and carnivorism often necessitate supplementation to adhere to personal beliefs, which can be counterproductive if not properly acknowledged. For instance, vegans might need to supplement with B12 and omega-3s, while carnivores might lack fiber and certain vitamins.
- Both communities struggle to substantiate their diets as superior concerning health, ethics, and environmental impact. For example, vegans emphasize reducing animal cruelty and lowering carbon footprints, while carnivores stress the naturalness of their diet and potential health benefits.
- The promotion of regenerative agriculture within the carnivore community is often highlighted positively. However, it assumes that followers can strictly adhere to sustainable practices, which may not be realistic for everyone.
- Bridging these ideologies requires understanding and addressing the nutritional gaps and environmental implications of each, focusing on factual evidence and flexible dietary practices rather than strict adherence.
