Episode notes
Carnivore Diet Increases Diversity
- A 90-day carnivore diet surprisingly increased gut microbiome alpha diversity.
- The shift favored bacteria metabolizing protein and fat, adapting the gut ecosystem functionally.
Microbiome's Functional Flexibility
- The gut microbiome adapts functionally by shifting bacteria to produce butyrates without plant carbs.
- This microbial flexibility supports maintaining gut health and metabolic functions on carnivore diet.
Akkermansia Spike in Carnivore
- Ben's Akkermansia bacteria increased significantly during carnivore, aiding fat metabolism and hormone regulation.
- This change likely contributed to his weight loss and improved satiety on the diet.
