CHAPTERS
- 0:03 – 1:01
Coffee, sourdough gifts, and why Ben won’t go full carnivore
Joe and Ben open with coffee talk and Ben’s homemade goodies, then pivot quickly into carnivore diet skepticism. Ben explains he’s too much of a foodie to go all-in, opting instead for a meat-heavy approach.
- •French press vs nitro cold brew banter
- •Ben’s sourdough bread and macaroons as ‘biohacker treats’
- •Ben declines strict carnivore; calls himself a partial carnivore
- •Sets up later discussion on meat-only as an elimination diet
- 1:01 – 2:56
Carnivore diet mechanics: TMAO, fiber, and nose-to-tail eating
They dig into concerns about high red-meat diets, especially TMAO and gut effects. Ben argues the context (fiber intake, microbiome balance, and nose-to-tail nutrition) changes whether markers are harmful.
- •Difference between gluconeogenesis sugars vs TMAO
- •High TMAO isn’t automatically bad if fiber intake is high
- •Traditional ‘carnivore’ cultures often consume organs/intestines
- •Methionine concerns and balancing with glycine/collagen sources
- •Nose-to-tail as the ‘safer’ carnivore approach
- 2:56 – 8:52
Anecdotes vs bloodwork: why carnivore can feel amazing
Joe contrasts strong anecdotal reports with unimpressive lab results he’s seen from some carnivore adherents. They frame carnivore as an effective elimination diet that may remove irritants rather than ‘heal’ by itself.
- •Disparity between subjective wellbeing and biomarkers
- •Jordan Peterson’s strict meat-and-salt example
- •Carnivore as autoimmune/elimination strategy
- •Gut-brain axis and inflammation’s systemic effects
- •Collagen/protein intake as a confounder for joint/gum improvements
- 8:52 – 11:30
Personalized nutrition and ancestry ‘cold spots’
Ben expands the conversation into diet personalization using genetics, microbiome, and ancestry patterns. He introduces the idea of geographic ‘cold spots’ where genetic risk doesn’t manifest due to traditional diets.
- •Self-quantification: genetics, blood markers, microbiome
- •Ancestry-informed eating as a practical framework
- •Iceland example: omega-3s buffering depression/SAD risk
- •Cameroon example: fiber-rich diets and colon-cancer protection

- 24:36 – 30:34
NAD, NMN/NR, and the anti-aging arms race (plus ‘young blood’ ethics)
Ben compares NAD to Sinclair’s NMN/NR discussion and explains why he thinks NAD may be better for neurological aims. They then debate parabiosis/young plasma businesses and Ben’s attempt at an ‘autologous’ alternative despite lack of published human evidence.
- •NAD vs NMN/NR: blood–brain barrier and use-case differences
- •Sirtuins, mitochondria repair, and uncertain pathways
- •Young plasma companies (Ambrosia) and lack of human studies
