This is 'Thirsty Hippo'. I've listened to probably 100+ hours of Peter Attia's podcast "The Drive." I read his book "Outlive" twice. And the thing that struck me most wasn't the science — it was how often he admits he was wrong.

Most health gurus double down when challenged. Attia does the opposite. He's publicly walked back positions on fasting, keto, metformin, and rapamycin. His routine in 2026 looks very different from his routine in 2018.

That's why I wanted to compile what he actually does now — not what clickbait articles claim, not outdated information from years ago, but his current practices based on his most recent podcast episodes and interviews.

솔직히 말하면, some of this surprised me. His routine is more moderate than his reputation suggests. And some of his strongest recommendations aren't sexy biohacks — they're embarrassingly basic.

👤 1. Who Is Peter Attia?

Quick background for those who don't know him:

• MD from Stanford, trained as a surgeon at Johns Hopkins
• Left traditional medicine to focus on longevity and preventive health
• Hosts "The Drive" — one of the most popular health podcasts (deep, technical, 2-3 hour episodes)
• Wrote "Outlive: The Science and Art of Longevity" (2023) — NYT bestseller for over a year
• Runs a medical practice focused on wealthy clients who want aggressive preventive care

He's known for being extremely data-driven and willing to experiment on himself. He's also known for being intense — the guy exercises 10+ hours a week and tracks his blood glucose continuously.

But here's the key thing: he's not selling supplements or programs. His income comes from his medical practice and book. So when he says something doesn't work, he has no financial reason to lie.

🏋️ 2. His Exercise Routine (The Real Numbers)

This is where Attia is extreme by any normal standard. He exercises 10-12 hours per week. That's not a typo.

Weekly Breakdown

Type	Frequency	Duration	What It Looks Like
Zone 2 Cardio	4x/week	45-60 min	Cycling, walking on incline treadmill. Can hold a conversation but wouldn't want to.
Strength Training	3-4x/week	45-60 min	Focus on hip hinge, carrying, pulling, grip strength. Not bodybuilding-style.
Stability/Mobility	Daily	15-30 min	DNS exercises, balance work, joint prep. His "unsexy but essential" category.
Zone 5 / VO2max	1x/week	20-30 min	High intensity intervals. The "suffering" workout.

Why Zone 2 Gets So Much Emphasis

Zone 2 is moderate cardio — hard enough to breathe heavier, easy enough to talk. Most people skip this and either do easy walking or intense HIIT. Attia argues Zone 2 is the "base" that everything else builds on.

The science: Zone 2 improves mitochondrial function and fat oxidation. It's the intensity where you're actually training your body to use fat efficiently. It's also low-injury-risk, so you can do a lot of it.

His test: Can you hold a conversation but you'd rather not? That's Zone 2. If you can sing, you're going too easy. If you can only grunt single words, you're too hard.

⚠️ The Realistic Version

10-12 hours/week isn't realistic for most people. Attia knows this. His advice for "normal humans": aim for 3-4 hours/week minimum — some Zone 2, some strength, prioritize consistency over perfection. 아직 그 정도도 어려운 사람이 많겠지만, that's the minimum effective dose.

😴 3. Sleep: His Most Non-Negotiable Habit

If Attia could only optimize one thing, he says he'd choose sleep. Not exercise. Not diet. Sleep.

His Sleep Protocol

• Duration: 8 hours of sleep opportunity (in bed ~8.5 hours)
• Temperature: Room at 65-67°F (18-19°C)
• Tracking: Oura Ring to monitor sleep stages
• Alcohol: Completely eliminated — he says even one drink destroys his sleep quality
• Caffeine cutoff: None after early afternoon (he's very caffeine-sensitive)
• Screens: Limits blue light exposure at night, uses f.lux/Night Shift

Why He's So Extreme About Sleep

Attia has talked openly about how his sleep was terrible for years during surgical training and his early career. When he finally fixed it, he says everything else improved — mood, exercise recovery, cognitive function, patience with his kids.

The data he cites: sleeping less than 7 hours is associated with higher all-cause mortality. Chronic sleep deprivation is linked to Alzheimer's, heart disease, and impaired glucose regulation. There's no "catching up" on weekends.

His blunt summary: "Sleep is not negotiable. You can't out-exercise or out-supplement bad sleep."

🥗 4. Diet: What He Actually Eats

This is where Attia has changed the most over the years. He used to be strict keto. Now he's not.

Current Approach

• Protein priority: 1 gram per pound of goal body weight (e.g., 180g/day if goal is 180 lbs)
• Carbs: Not restricted, but limits refined carbs and added sugar
• CGM: Uses continuous glucose monitor to see personal responses to foods
• Fasting: Occasional time-restricted eating, but no longer does extended fasts (3+ days)
• Alcohol: Zero. Completely eliminated.

Why He Left Keto

Attia followed strict ketogenic diet for years. He's walked this back significantly. His reasons:

1. Hard to maintain adequate protein on strict keto
2. His athletic performance suffered (especially high-intensity work)
3. The benefits he thought were from keto might have been from calorie restriction
4. Sustainability matters — he couldn't see doing it for 50 more years

His current philosophy: "Nutrition is the hardest domain. There's no one-size-fits-all. But almost everyone should eat more protein and less processed food. That's 80% of the battle."

💊 5. Supplements: What He Takes (and Stopped Taking)

This is where people get most confused. Attia's supplement list has changed a lot.

What He Currently Takes

• EPA/DHA (fish oil) — for omega-3, targets specific blood levels
• Vitamin D — aims for blood level of 40-60 ng/mL
• Magnesium — L-threonate or glycinate form
• Methylated B vitamins — B12, folate

What He STOPPED Taking

• Rapamycin — used to take for longevity, stopped due to uncertain risk/benefit
• Metformin — used to take, now believes exercise provides same benefits without downsides
• NAD+ precursors (NR, NMN) — stopped, says evidence is weak
• Resveratrol — stopped, doesn't believe it does anything meaningful

His blunt take: "Supplements are maybe 1% of the equation. If you're not sleeping 8 hours and exercising, don't even think about supplements. You're rearranging deck chairs on the Titanic."

🔄 6. What He's Changed His Mind About

This is what I respect most about Attia. He publicly updates his views when evidence changes.

Topic	Old View	Current View (2026)
Keto Diet	The optimal diet for most people	One tool of many. Not superior. Protein matters more than carb restriction.
Extended Fasting	7-day fasts quarterly for autophagy	No longer does extended fasts. Concerns about muscle loss outweigh benefits.
Metformin	Promising longevity drug	Stopped taking. May blunt exercise benefits. Not worth the trade-off for healthy people.
Rapamycin	The most promising longevity drug	Stopped taking. Still interested, but human evidence not strong enough to justify risks.
Emotional Health	Rarely discussed	Now calls it a major pillar. Wrote a whole chapter on his own therapy in "Outlive."

이건 좀 의외인데, the biggest shift might be emotional health. The "hard science" longevity doctor now talks openly about going to therapy, his anger issues, his workaholic tendencies. He says improving his emotional health did more for his wellbeing than any supplement ever did.

🎯 7. The "Centenarian Decathlon" Concept

This is one of Attia's most useful frameworks. Instead of vague "I want to be healthy," he asks: What do you want to be physically capable of at age 100?

Examples from his personal list:

• Pick up a grandchild from the floor (hip hinge, grip strength)
• Get up from the floor without using hands (mobility, leg strength)
• Carry groceries up stairs (loaded carrying, cardio)
• Play 18 holes of golf (walking endurance, rotation)
• Swim with grandkids (full body, cardio)

The math: Physical function declines about 8% per decade after 40. If you need to deadlift 100 lbs at age 100, you need to deadlift ~180 lbs at age 60. So train NOW for what you want to do THEN.

This framework changed how I think about exercise. It's not about looking good at 40. It's about being functional at 90.

Q5. What is the main message of "Outlive"?

A. The main message is that we should shift from treating disease after it appears to preventing it decades earlier ("Medicine 3.0"). The four pillars are exercise (most powerful drug), nutrition, sleep (non-negotiable), and emotional health (most overlooked).

📝 The Unsexy Truth

After reading everything Peter Attia has written and said, here's the uncomfortable conclusion: the most effective longevity interventions are boring.

• Sleep 8 hours. Every night.
• Exercise more than you think you need to. Especially Zone 2 and strength.
• Eat enough protein. Limit junk.
• Don't drink alcohol (or minimize it heavily).
• Address your emotional health. Go to therapy if needed.

That's it. No fancy supplements. No exotic biohacks. No magic pills. The doctor who's read all the longevity research has concluded that the basics — done consistently, for decades — are what actually matter.

The hard part isn't knowing what to do. It's actually doing it, every day, when no one's watching.
