The Joe Rogan ExperienceJoe Rogan Experience #1235 - Ben Greenfield
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.
- 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.
- 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.
- 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.
- 11:30 – 12:33
Spokane/Coeur d’Alene: beautiful nature, heavy metals, and detox tangents
The discussion detours into Ben’s home region and Coeur d’Alene’s striking clarity contrasted with mining-related metal pollution. This leads naturally into sauna and detox questions.
- 12:33 – 17:19
Infrared vs dry sauna: depth of heat, longevity studies, and ‘suffering’ preferences
Ben outlines the theory behind infrared saunas (lower air temp, deeper tissue penetration) while Joe emphasizes Finnish dry-sauna research popularized by Rhonda Patrick. They compare detox claims, performance effects, and comfort factors.
- 17:19 – 20:31
Cryotherapy and Upgrade Labs gadgets: Vasper, BFR cuffs, and quick-hormone spikes
Ben describes hotel-based biohacking setups and a Vasper workout combining cold and blood-flow restriction. They discuss purported boosts in growth hormone/testosterone and the uncertainty around duration and evidence quality.
- 20:31 – 24:36
Brain and longevity interventions: photobiomodulation, TBI protocols, and DIY IVs
The conversation moves into head-worn light devices and neurological recovery strategies. Ben details controversial self-experimentation: IV mannitol to open the blood–brain barrier and NAD ‘push’ protocols, stressing medical supervision while describing his routine.
- 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.
- 30:34 – 43:25
Joint repair tools: hydrodissection, ozone/placental extract, exosomes, and peptides
Ben describes nerve hydrodissection for knee pain and rapid recovery claims, while Joe shares his experience with exosomes and a rotator cuff tear that appears healed on MRI. They compare peptide options and note shifting trends and regulatory limits.
- 43:25 – 49:22
Muscle memory science and doping implications in combat sports
They discuss myonuclei retention and why past steroid use may confer long-term advantages even after stopping. The conversation shifts into MMA’s anti-doping realities, Jon Jones’ metabolite controversy, and untested grappling scenes.
- 49:22 – 1:22:46
THC/CBD for performance and recovery: reaction time, mTOR, entourage effect, and new cannabinoids
Ben and Joe debate marijuana’s effects on reaction time and complex tasks, distinguishing acute vs chronic tolerance. Ben explains CBD/THC ratios used by endurance athletes and the industry trend toward isolating specific cannabinoids and terpenes for targeted outcomes.
- 1:22:46 – 1:29:25
Metformin skepticism, CGMs, and ‘natural’ glucose control alternatives
Ben warns Joe about metformin side effects and argues many benefits can be achieved via lifestyle and supplements. He describes using a continuous glucose monitor to discover personal glucose triggers (coffee, green beans) and critiques common food-sensitivity testing pitfalls.
- 1:29:25 – 1:41:16
Biohacking philosophy: go natural first (earthing, red light, PEMF) and fix your environment
Ben defends biohacking while emphasizing foundational ‘natural’ practices before gadgets. They cover grounding research claims, PEMF mats, red-light exposure (including testicular photoreceptors), standing/treadmill desks, and constant posture variation at work.
- 1:41:16 – 1:50:49
Circadian rhythm resets, fasting routines, and ketone ‘rocket fuel’
They compare strategies for travel recovery: light exposure, timing meals, movement, and fasting. Ben details his layered fasting protocol (daily intermittent, quarterly fasting-mimicking, periodic 24-hour fasts) and discusses ketone esters + amino acids for hard training while fasted.
- 1:50:49 – 1:59:49
Mushrooms, microdosing stacks, and ‘doctrine of signatures’ (plus topical CBD hacks)
They riff on functional mushrooms (cordyceps, lion’s mane) and Ben’s preferred cognitive stack: lion’s mane + microdose psilocybin + blood-flow enhancer. The chapter also includes topical recovery tactics like using EMS + ice to drive CBD deeper, and a broader warning about endocrine disruptors in personal care products.
- 1:59:49 – 2:11:52
Sleep optimization: CBD vs THC, trackers, breathwork, and why Ambien is a trap
Ben explains dosing realities for CBD research and contrasts its deep-sleep effects with THC’s sleep-latency benefits but reduced deep sleep. They criticize pharmaceutical sleep aids, emphasize breathwork as a first-line tool, and discuss how sleep improves decision-making and emotional regulation.
- 2:11:52 – 2:22:52
Food craft returns: healthy treats, grass-fed beef benefits, and ‘clean’ Celtic salt
The conversation winds down with Ben’s family cooking experiments (bone-broth marshmallows) and a nutrition deep dive into fatty acid ratios, nuts, and grass-fed vs grain-fed beef. They end on salt: lab-tested mineral/metal profiles and Ben’s case for Celtic sea salt, plus sweat sodium individuality.
