Can carnivore and vegan diets both be used as ketogenic therapies?
In this episode of Metabolic Mind, Dr. Bret Scher speaks with registered dietitian Denise Potter about two widely debated approaches to nutrition. They explore how each can be evaluated when someone is considering a ketogenic diet to support psychiatric, neurological, or metabolic health.
Denise brings more than 30 years of clinical experience, including approximately 20 years working with medical ketogenic therapies. She explains the importance of risk-benefit analysis, how clinicians can assess potential nutrient gaps, and how lab testing, supplementation when indicated, and individualized support may help identify and manage potential risks.
They cover:
- The difference between a carnivore diet and a carnivore ketogenic diet
- Why some people report mental and physical health improvements with carnivore ketogenic approaches
- Common questions about vitamin C, iodine, electrolytes, fiber, calcium, omega-3s, and LDL
- Why bowel habits and the microbiome require clinical context
- How a vegan ketogenic diet can be formulated, including Denise’s recommendation to pay close attention to B12 supplementation
- Protein quality, bioavailability, and amino acid considerations in vegan ketogenic diets
- The role of tracking, lab work, and follow-up testing
- How clinicians can evaluate restrictive dietary patterns through a medical risk-benefit lens
This conversation offers a practical look at how different ketogenic approaches may be designed, monitored, and adjusted with individualized guidance and appropriate clinical support.
💡 Whether you’re considering a carnivore ketogenic approach or a more plant-based one, the quality of the diet itself can make a significant difference in outcomes.
