Nutrition & Diet

In their own words

Huberman says he has doubled down on five foundational categories that must be re-upped every 24 hours: sleep, nutrients (macro and micro), movement, light (especially morning sunlight), and relationships.
00:05:08Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
He reversed his belief that you cannot train for endurance and strength at once; the data on concurrent training convinced him you can pursue multiple adaptations simultaneously, so he rebuilt his program to target one specific adaptation each day.
00:22:50Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
He details his full weekly split: Sunday endurance hike/jog, Monday legs, Tuesday sauna/cold plunge recovery, Wednesday cardio or torso, Thursday torso or cardio, Friday short VO2 max work, Saturday smaller muscle groups.
00:24:34Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Tibialis (tib) raises, learned from Ben Patrick (Knees Over Toes Guy), eliminated his right-side sciatica, fixed shin splints, and let him run pain-free; he also discovered he never actually had flat feet, just weak tibs.
00:33:01Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Dedicated neck training improved his posture, eye contact, confidence, and injury resilience; he does it lying on a bench and stomach with a towel-wrapped plate.
00:50:39Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
His sleep stack remains magnesium threonate, theanine, and apigenin, with added myo-inositol (900 mg) to help fall back asleep; if forced to pick two, he chooses magnesium threonate and apigenin.
01:15:41Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Rhodiola rosea (200 mg pre-workout) is his standout recent performance addition because it reduces perceived effort and post-exercise energy crash without suppressing cortisol, unlike Ashwagandha.
01:36:34Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Huberman has been monitoring sperm parameters and freezing sperm, and credits Ferriss with the idea that optimizing for fertility is a proxy for optimizing overall vitality.
01:44:32Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
The circuits devoted to movement plus those devoted to vision make up roughly 75 percent of the human brain.
00:21:12Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
After about 25-30 minutes of repetitive exercise, central pattern generators engage so the movement becomes near-automatic, like an autopilot button appearing on the steering wheel.
00:28:43Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Protein synthesis peaks around 48 hours after a resistance workout but is held for additional days, so a muscle group does not need to be hit every 48 hours.
00:59:29Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Charles Poliquin's caution: resistance training beyond 60 minutes raises cortisol, harming sleep and recovery, so Huberman keeps lifts to an hour or less.
01:02:43Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
A University of Houston study found 'soleus pushups' (seated calf raises) done while sitting significantly improved insulin sensitivity and glucose uptake.
01:10:48Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
The soleus is about 1 percent of body musculature but can account for over 15 percent of daytime energy expenditure.
01:11:54Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Gulping fluid signals the bladder to urgently urinate, so sip your last evening drink, but gulp large amounts of water first thing in the morning when the kidney functions differently.
01:18:23Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Morning light raises cortisol about 50 percent above baseline; late-shifted cortisol is associated with depression and immune disruption.
01:21:03Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Neuropod cells in the gut signal sugar, fatty acids, and amino acids via the vagus nerve to the brain's dopamine centers, driving cravings and satiety.
01:29:06Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
An Israeli study found 20 minutes of afternoon sun on bare skin three times a week significantly increased free testosterone, estrogen, and libido; the skin acts as an endocrine organ via the P53 pathway.
01:53:41Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
On 'unoptimized living,' Tim explains he is simultaneously optimizing (Occam's Protocol strength training, recently gaining 10-15 lbs of muscle) and deliberately deoptimizing other areas, arguing you can't optimize everything and life is about trade-offs.
00:02:50Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim names 'digital emotional surrogacy' as the under-discussed trend, predicting photorealistic VR avatars and companions like Replika will become a replacement—not just a supplement—for human interaction within about two years.
00:41:30Tim Ferriss · The Tim Ferriss Show · Nov 2023
To counteract the loneliness epidemic as an introvert, Tim books trips and time with friends/family roughly six months in advance, putting money behind them to exploit the sunk-cost fallacy so he won't cancel.
00:44:15Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim predicts an explosion of new 'religions' (some masquerading as CrossFit, veganism, etc.) plus renewed uptake of Abrahamic faiths, arguing everyone worships something and the most at-risk people don't know what they worship.
00:53:46Tim Ferriss · The Tim Ferriss Show · Nov 2023
On longevity, if forced to pick one form of exercise, Tim chooses resistance/weight training, because progressive resistance is easy to quantify and weight loss isn't sustainable without upgrading underlying muscle/mitochondrial 'machinery.'
00:55:23Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim details his low-back pain protocol: Fisher Traction door device, internal/external rotation work, terminal hip extension when walking, Hyperice foam rolling, a portable pillow, and proper chair ergonomics for L5 stenosis from a bulging disc.
01:11:50Tim Ferriss · The Tim Ferriss Show · Nov 2023
On interviewing, Tim reveals he gives guests final cut, spends 5-10 minutes building rapport before recording, and pursues 'side alleys'—how he uncovered Debbie Millman's first public account of childhood sexual abuse.
00:59:54Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim discloses a five-year relationship ended about a year ago, that the past year was extremely stressful, and that while his back issues are structural, emotional components (per Sarno) likely also play a role.
01:14:39Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim donates monthly to Charm Industrial (which puts oil back underground, charmindustrial.com) and uses Terraset Climate to offset his travel carbon footprint.
00:00:35Tim Ferriss · The Tim Ferriss Show · Nov 2023
His rustic home is intentionally meant to be lived in and even 'abused'—scratches and wine stains from social use—not treated like a museum, with a deliberately autumn-themed backsplash.
00:13:50Tim Ferriss · The Tim Ferriss Show · Nov 2023
For skincare, Tim uses only Dr. Bronner's unscented Castile soap for face, head, and body, avoids most sunscreen (preferring zinc oxide and long sleeves), and works 'inside out' with Nordic Naturals omega-3s.
00:20:56Tim Ferriss · The Tim Ferriss Show · Nov 2023
To maintain multiple languages, Tim links them via the manga One Piece—using his most recent prior language as the 'safety net' to learn the next, since comics are dialogue-heavy and map pane-by-pane.
00:33:06Tim Ferriss · The Tim Ferriss Show · Nov 2023
For dog training, Tim recommends Karen Pryor's 'Don't Shoot the Dog' and clicker training, citing the quote 'No one should be allowed to have a child until they've been forced to train a chicken.'
00:35:55Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim warns of capability atrophy ('if you don't use it, you lose it'), citing how older generations navigate better offline than younger ones reliant on Google Maps, and advocates being a 'selective Luddite.'
00:46:28Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim distinguishes his fear of the 'descent to death' (losing health span and cognition) from fear of death itself, which he manages via Stoicism (Marcus Aurelius, Epictetus, Seneca) and ego-dissolving experiences.
01:08:31Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim consumes Maui Nui venison sticks (9-11g protein each, three for his 30g) and invested in the company; he calls it the most nutritionally dense meat in the US.
01:05:03Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim strongly endorses Pilates 2-3x/week with a technical instructor for core, pelvis position, and injury prevention, saying he'd tell his 30-years-younger competitive self to do it.
01:16:52Tim Ferriss · The Tim Ferriss Show · Nov 2023
Tim is excited to go backcountry and sidecountry ski touring this winter on DPS touring skis he bought last season.
00:17:43Tim Ferriss · The Tim Ferriss Show · Nov 2023
In Kjaer's study, patients who loaded an injury at day two after injury returned to sport 25% faster than those who waited nine days to load.
00:47:43Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Eccentric loading for tendons was a 'false positive' — it worked because of slow velocity, not the eccentric motion itself; heavy strength training has the identical effect, and zero velocity (isometric) gives the biggest bang for the buck.
00:22:50Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
A boot or RICE is a 'mechanical stress shielder' that removes the tension tendons need to heal, so the standard orthopedic treatment can actually make the injury worse and cause scarring.
00:00:00Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
BPC-157 has no direct effect on tendon or ligament cells — engineered human ligaments treated with it showed no change in mechanics, collagen, or strength.
01:06:58Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Women are four to eight times more likely to rupture their ACL because estrogen periodically inhibits a collagen cross-linking enzyme, lowering tendon stiffness during parts of the menstrual cycle.
01:23:19Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Physical therapist Rob Whitley told a room of orthopedic surgeons that PRP, stem cells and prolotherapy show no benefit in randomized controlled trials — only getting load through the tissue works.
01:13:51Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Mice on a ketogenic diet lived 13% longer than controls, an effect comparable to rapamycin, and old keto-fed animals had strength and brain function at the level of young animals.
01:33:43Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Connective-tissue cells need only about 10 minutes of loading (e.g. 10s on, 50s off) to get the full adaptation signal, then a six-to-eight-hour refractory period before responding again — matching bone's response to as few as 40 stimuli.
00:08:19Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Tendon stress relaxation drops exponentially; by 30 seconds you reach about 85% of the bottom, and waiting two minutes only adds about 15% more — hence 30-second holds for injured tendons.
00:26:29Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Three days in a 3D-printed cast cost a mouse tendon 15–20% of its collagen and made it roughly 30% mechanically weaker — a larger loss than the muscle itself.
01:08:34Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Fluoroquinolone antibiotics like ciprofloxacin raise Achilles rupture rate about 3.5-fold, while AT-1 (angiotensin) receptor blocking 'sartan' blood-pressure drugs taken by 15+ million Americans raise it 7.6-fold.
01:19:39Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
On keto, no carbohydrate forces reliance on mitochondria, and lowered mTOR triggers 'mitophagy' that culls weak mitochondria — but keto severely harms bone mass, which is why epileptic kids must eventually cycle off it.
01:36:51Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Using a resorbable suture in Achilles repair allowed native tissue to recover and produced better collagen-synthesis markers than non-resorbable, with no difference in tendon length — contradicting surgeons' fears.
00:54:32Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Testosterone activates lysyl oxidase and decreases collagen, creating stiff but brittle tendons — explaining why steroid-using baseball players' performance would suddenly 'drop off a cliff' from tendon ruptures.
01:26:25Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Rupturing your ACL makes you 50% more likely to have a heart attack, driven by the habitual decrease in activity that follows the injury.
01:13:19Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
A 2017 study found ~15g gelatin plus ~200–250mg vitamin C taken an hour before brief exercise doubled blood markers of new collagen formation versus control.
01:01:17Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
The 'refractory period' for tendons is why Emil Abrahamsson's brother, with many injuries, did isometric hangs twice a day (six-plus hours apart) and got his hands healthy.
00:08:19Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
A ketogenic diet quiets the brain by lowering glutamate and elevating GABA, a calming neurotransmitter, which underlies its rapidly expanding use in metabolic psychiatry for depression, bipolar, schizophrenia, anxiety, and anorexia.
00:02:38Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
Lyme disease spirochetes (Borrelia) are essentially 100% glycolytic, so limiting glucose starves the microbe, and elevated beta-hydroxybutyrate stimulates the adaptive immune response, possibly explaining why ketosis resolved Tim's tick-borne cognitive symptoms.
00:11:25Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
Tim's very low blood ketone readings (0.1 to 0.4 mmol) despite feeling sharp are likely a false negative caused by very high ketone utilization and insulin sensitivity, meaning his tissues consume ketones before they show up in the blood.
00:32:42Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
You can get about 80% of the benefits with a low-carb diet (around 100g carbs/day) and periodically, roughly one week per month, drop into deeper ketosis, since higher ketones are not better and a sweet spot of 1 to 2 mmol is therapeutic.
01:07:00Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
1,3-butanediol and 1,3-butanediol-based ketone esters can cause chronic liver toxicity (depleting NAD and ATP, causing inflammation and fatty liver), and animals showed scary liver damage even when blood liver enzymes stayed normal.
01:31:54Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
1,3-butanediol is metabolized like ethanol, creates dependence and alcohol-like withdrawal, and is sold as an alcohol replacement, making these supplements dangerous for the elderly dementia population some companies target.
01:50:39Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
On a ketogenic diet, roughly 34 to 40% of the ketone in the heart is L-beta-hydroxybutyrate, which appears to improve cardiac output and increase blood flow to the brain by reducing peripheral vascular resistance.
01:22:33Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
Metabolic memory is real: like muscle memory, the more you stay in ketosis the faster your body re-adapts, driven by increased mitochondrial number and capacity plus epigenetic gene programs.
00:17:40Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
There are 160 or more registered clinical trials on exogenous ketones listed on clinicaltrials.gov.
00:05:14Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
About 80% of cancers are highly glycolytic, and while a ketogenic diet does not cure cancer it can slow tumor growth and augment standard care like radiation and chemo.
00:14:33Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
Tim's staple keto meal is two cans of chub mackerel with about 30ml of MCT oil plus apple cider vinegar, salt, and pepper, costing around three dollars.
00:23:59Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
Breath ketones (acetone) can be a more accurate indicator of ketosis than blood ketones during a caloric deficit, when blood ketone disposal into tissues is very high.
00:33:43Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
A B12 deficiency can cause brain atrophy and present as flat-out Alzheimer's disease, but can be reversed by correcting the deficiency.
00:59:42Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
High-sensitivity C-reactive protein (HSCRP) inflammation is now considered probably more atherogenic than LDL cholesterol.
01:00:13Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
To calculate the glucose-ketone index (GKI), divide blood glucose by ketone level; US glucose readings in mg/dL must first be divided by 18 to convert to mmol/L.
01:16:20Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
The only long-term human data on 1,3-butanediol is a single case report (Mary Newport's husband Steve) and a 28-day study using 25 grams per day.
01:35:33Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
The ketone ester traces back to Dr. Richard Veech, a student of Hans Krebs of the Krebs cycle; the work was funded in part by DARPA and developed at Oxford.
01:55:52Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
Ketones above the 2 to 5 mmol range create energy toxicity and reductive stress, so higher is not better for general therapeutic ketosis.
01:57:55Dr. Dom D'Agostino · The Tim Ferriss Show · Jan 2026
Stupple's family practices no sleep schedules, unrestricted screen time, no forced school, no chores, no forced sharing, no forced teeth-brushing, and no punishments or timeouts.
00:08:21Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025

00:10:24Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025
Naval reveals he is restrictive in only two areas: insisting on math and reading ('until then you're a little slave'), and stopping kids from hitting each other.
00:22:19Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025
Stupple reframes knowledge itself as constraint, arguing that as knowledge progresses constraints get tighter, and good constraints are ones you can opt out of.

Naval claims mandatory public education originated as forced assimilation during empires, with conquered peasants hiding children to keep them from school.
01:39:35Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025
Stupple lays out four categories of harm caused by rules: adversarial gatekeeping, damage to self-relationship/self-confidence, confusion about the actual issue, and a conformist deference to authority.
01:53:35Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025
Stupple's top ER survival tip: bring multiple copies of an accurate medication list, because the hospital's records almost never match what the patient actually takes.
02:04:01Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025
Aaron Stupple has five kids ages 7 to 1; Naval was joking when he said Aaron has zero children.
00:04:43Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025

Stupple once dumped a whole bag of lollipops on the floor for his three-year-old, who licked about 20, got bored, and abandoned them, learning lollipops get gross.
01:16:46Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025
Stupple cites Judith Rich Harris's meta-research concluding child outcomes are mostly genetic, with the nurture portion driven by peers rather than parents.
01:50:30Naval Ravikant and Aaron Stupple · The Tim Ferriss Show · Jan 2025

00:14:36Tim Ferriss · The Tim Ferriss Show · Jun 2021
Tim reveals he is no longer hesitating about having children and is actively seeing fertility doctors, going through the 'pre-flight checklist'; his past hesitation stemmed from doubts about being a good father and a genetic predisposition to depression.
00:31:47Tim Ferriss · The Tim Ferriss Show · Jun 2021
On self-compassion versus grinding, Tim argues there are counter-examples of friends with outsized financial success who were not self-flagellating, concluding self-compassion carries very little downside even in your 20s and 30s.
00:39:06Tim Ferriss · The Tim Ferriss Show · Jun 2021
Tim shares his 'jacket/smoking jacket' analogy: meditation and therapy don't make you lose your edge; you simply learn to take the edge off and put it back on when genuinely needed, as he did to handle a stalker threatening his family.
00:41:39Tim Ferriss · The Tim Ferriss Show · Jun 2021
Tim breaks down 'ontological shock' (a term he first heard from Roland Griffiths), explaining how a single mystical or trauma-surfacing experience can take weeks, months, or years to reconcile with ordinary reality.
00:47:52Tim Ferriss · The Tim Ferriss Show · Jun 2021
On the fear of being misunderstood, Tim offers the reframe that we dramatically overestimate how much others think about us, since everyone is the lead actor in their own 'me me me movie.'
01:05:29Tim Ferriss · The Tim Ferriss Show · Jun 2021
Tim's morning routine starts with 20 minutes of meditation (often transcendental meditation), then Pique tea or coffee, often with Four Sigmatic mushroom coffee and Laird superfood creamer.
00:06:54Tim Ferriss · The Tim Ferriss Show · Jun 2021
He organizes his week thematically, batching activities like phone calls into dedicated days (e.g., Tuesdays) rather than spreading them across every day.
00:07:55Tim Ferriss · The Tim Ferriss Show · Jun 2021
His exercise routine includes acro yoga twice a week (started in quarantine via Zoom with instructor Jason Nemer), climbing twice a week, weight training 1-2 times, and substantial daily walking.
00:08:26Tim Ferriss · The Tim Ferriss Show · Jun 2021
Holotropic breathwork was created by psychiatrist Stan Grof as an alternative to psychedelics after they were made illegal; 'holotropic' means turning toward wholeness.
00:18:46Tim Ferriss · The Tim Ferriss Show · Jun 2021
Tim warns that legitimate well-trained indigenous practitioners essentially never call themselves 'shamans'; self-described shamans are a red flag.
00:21:22Tim Ferriss · The Tim Ferriss Show · Jun 2021
For joint pain he uses Kelly Starrett's Voodoo Floss and contrast therapy via a chest freezer converted into a cold plunge (he warns to unplug it first to avoid electrocution).
00:23:25Tim Ferriss · The Tim Ferriss Show · Jun 2021
Tim notes that doing intense breathwork (like Wim Hof or holotropic) after a psychedelic dose can have a multiplicative effect, making 50 micrograms of LSD subjectively feel like 100-200.
00:30:44Tim Ferriss · The Tim Ferriss Show · Jun 2021
He is back on the slow-carb diet and still aims for a 72-hour water fast once per month plus at least one week-long fast per year.
00:44:14Tim Ferriss · The Tim Ferriss Show · Jun 2021
Tim reads roughly three to five hours per week, typically before bed for 30-60 minutes, significantly more when traveling.
01:00:50Tim Ferriss · The Tim Ferriss Show · Jun 2021
For sleep he uses California poppy, magnesium L-threonate, the Oura ring for tracking, and an Eight Sleep bed cover, noting caffeine's quarter-life is about 12 hours.
01:10:41Tim Ferriss · The Tim Ferriss Show · Jun 2021
After years of aggressive fasting (up to 10-day water-only fasts, routine 7-day fasts quarterly), Attia was shocked by a DEXA scan showing how much muscle he had lost over a decade.
00:02:22Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
He regained roughly 13-14 pounds of lean mass in about 12 months without anabolic steroids by prioritizing protein, timing, and hypertrophy training.

00:19:48Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
VO2 max and muscular strength stand 'in a league of their own' for longevity, outweighing the downside risk of conditions like diabetes, obesity, smoking, and high blood pressure.
01:14:32Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
Moving from the bottom 25% to the 25th-50th percentile of fitness cuts all-cause mortality risk roughly in half, with no drug matching that effect.
01:16:36Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
After a 6-9 month deep dive, exercise emerged as the single most important modifiable behavior to reduce risk of Alzheimer's, Parkinson's, and Lewy body dementia.
01:44:58Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
Treating cancers caught early produces vastly better outcomes than the same cancer caught late: ~80%+ ten-year survival for resected early colon cancer versus very few surviving five years with metastatic disease.
01:56:51Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
Attia reveals he spent time in a rehabilitation center where, on day 19, he had a breakthrough that let him finally write 47 self-affirmations he then read twice daily for six months.
02:09:44Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
Attia targets about 1 gram of protein per pound of body weight, spread across servings of roughly 20-50 grams to avoid gluconeogenesis and maximize muscle protein synthesis.
00:06:08Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
He tracks his eating with an app called Carbon, focusing on hitting leucine, lysine, and methionine targets (about 6-8g leucine, comparable lysine, at least 2g methionine daily).
00:10:01Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
Attia no longer uses BCAAs during workouts (just an electrolyte drink) and relies on high-quality whey protein post-workout instead.
00:11:05Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
Despite the 1971 War on Cancer aiming to eradicate the disease by 1976, cancer survival is barely 5% better than it was in 1970.
00:29:59Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
A hemoglobin A1C of 6.5% corresponds to an average blood glucose of about 140 mg/dL; lower average glucose correlates with lower all-cause mortality even in non-diabetics.

Attia wants patients able to carry half their body weight in each hand for one minute; grip strength repeatedly correlates with longevity and lower dementia risk.
01:27:35Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
He rucks with 55-60 pounds, recommending beginners start at one-sixth to one-third of body weight; Michael Easter's The Comfort Crisis notes the military caps useful loads around a third.
01:29:13Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
For VO2 max, spend about 80% of aerobic time in zone two (long, slow) and the rest in zone five intervals of 3-8 minutes, like a four-by-four workout once a week.
01:32:57Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
Key biomarkers Attia tracks: apoB, Lp(a), APOE genotype, uric acid, homocysteine, insulin, liver function, and Cystatin C (which he calls far more accurate than creatinine for kidney function).
01:54:42Dr. Peter Attia · The Tim Ferriss Show · Mar 2023
On the GRAIL liquid biopsy, early-stage sensitivity is only ~20% overall, but jumps to ~75% for aggressive hormone-negative (triple negative) breast cancer, suggesting it detects cancer behavior, not just presence.

After 20-plus medications failed over 8-9 years, Baszucki's son saw progress on a ketogenic diet within 3-4 weeks, which Baszucki calls 'a miracle' and the catalyst for the family's whole metabolic-health mission.
00:06:53David Baszucki · The Tim Ferriss Show · Nov 2025
In December 2017 his son ran away full-blown manic, flushed his meds, streamed himself on social media, bused to San Diego and slept in a lifeguard shack; Baszucki recounts an elaborate rescue tricking him into a hospital via a fake steak-dinner and hand-injury checkup.
00:07:25David Baszucki · The Tim Ferriss Show · Nov 2025
On a family trip to Mexico, avocados carried more carbs than expected and nudged Matt out of ketosis within days, bringing back manic symptoms; switching to just fish and butter popped him right back in, showing how tight the correlation is.
00:22:36David Baszucki · The Tim Ferriss Show · Nov 2025
Roblox had great user/hours growth but lagging revenue under an old $5/month membership model; the team eventually committed to building a full Robux digital economy and knew within four hours of shipping that it worked.
00:57:38David Baszucki · The Tim Ferriss Show · Nov 2025
Within four hours of launching the Robux economy, 22 of the top 100 creators had already integrated Robux features and users were already buying and spending, confirming the bet.
01:05:32David Baszucki · The Tim Ferriss Show · Nov 2025
Baszucki says one of Roblox's best decisions was optimizing creator revenue over company profit, leaning cash back to developers rather than being a 'ridiculously profitable company.'
01:12:52David Baszucki · The Tim Ferriss Show · Nov 2025
By end of year, Roblox plans to use AI age estimation via phone cameras to know users' ages and cluster people by age, blocking communication between users of widely different ages.
01:29:01David Baszucki · The Tim Ferriss Show · Nov 2025
Ketones are a 'more primitive' second energy pathway the body enters during fasting or very-low-carb eating; Baszucki ties bipolar symptoms to the brain not getting consistent energy amid glucose spikes and crashes.
00:17:56David Baszucki · The Tim Ferriss Show · Nov 2025
Matt's diet is under 20g of carbs per day and higher in fat than protein; Baszucki notes a quarter of a Coke has roughly 20g of carbs.
00:20:01David Baszucki · The Tim Ferriss Show · Nov 2025
Continuous ketone monitors (CKMs) are sold in Canada but not yet approved in the US; Baszucki jokes he's in a 'smuggling ring' bringing them across the border.
00:29:58David Baszucki · The Tim Ferriss Show · Nov 2025
After Wim Hof-style breathing at roughly 3 millimolar ketones, Ferriss extended a breath hold from about 45 seconds to 2 minutes 50; on day nine of a 10-day fast in a hyperbaric chamber he reached 9 minutes.
00:33:36David Baszucki · The Tim Ferriss Show · Nov 2025
Ferriss gives Alzheimer's relatives 25-30 mL of BHB exogenous ketones and sees noticeably longer sentences and improved verbal acuity within 20-30 minutes; Alzheimer's is sometimes called 'type 3 diabetes.'
00:38:16David Baszucki · The Tim Ferriss Show · Nov 2025
Ferriss credits 3 weeks of strict ketosis with resolving his post-Lyme cognitive symptoms, and reports a 4-5 out of 5 success rate with friends' documented Lyme cases.
00:40:52David Baszucki · The Tim Ferriss Show · Nov 2025
Roblox has about 120 million daily users, roughly 9 billion hours of engagement per month, peaks over 40 million concurrent users, and accounts for about 3% of all gaming worldwide.
00:49:46David Baszucki · The Tim Ferriss Show · Nov 2025
Roblox creators earned more than $1 billion in the past year, with thousands able to make a living and at least thousands earning over a million dollars.
00:55:31David Baszucki · The Tim Ferriss Show · Nov 2025
Roblox gives every employee a CGM and labels all office snacks on two axes (whole-food and 'good energy'), inspired by Casey Means' book.
01:43:59David Baszucki · The Tim Ferriss Show · Nov 2025
Baszucki's billboard message is 'Feed your head' (a Surrealistic Pillow reference), and he closes recommending heavy cream in coffee as an easy entry to ketosis.
01:48:41David Baszucki · The Tim Ferriss Show · Nov 2025
Marco's single biggest CGM takeaway: take a short walk after you eat, because even a roughly 14-minute walk dramatically reduces your blood sugar spike regardless of what you ate.
00:42:10Marco Canora · The Tim Ferriss Show · Nov 2021
His second big CGM insight was combining macronutrients; eating a 3,000-calorie indulgent dinner with lots of fiber, fat, and protein kept his glucose spike surprisingly low.
00:45:19Marco Canora · The Tim Ferriss Show · Nov 2021
Tim found that lowering his Eight Sleep bed temperature after drinking two glasses of wine suppressed alcohol's symptoms and produced much better Oura ring sleep scores.
