Peter Attia (physician) and Rhonda Patrick (biomedical scientist) side by side: how they train, eat, supplement and sleep, how strong the evidence is, and how to build a plan from either or both.

Build a plan from bothSee the protocols
Words explained (14)
Zone 2
Steady cardio at a pace where you can still talk in full sentences, but not sing.
VO2 max
The most oxygen your body can use in hard exercise. A good measure of fitness; higher is better.
Intervals
Short hard efforts with easy recovery in between, such as 30 seconds fast, 90 seconds slow.
4 × 4
Four rounds of 4 minutes hard with 3 minutes easy in between. Also called Norwegian intervals.
Hinge
A movement that bends at the hips with a straight back, like a deadlift or picking a box up from the floor.
Mobility
Moving your joints freely through their full range.
Creatine
A well-studied supplement that supports strength and muscle.
Omega-3 (EPA, DHA)
Healthy fats found mostly in oily fish such as salmon, herring and sardines.
Time-restricted eating
Eating all your meals within a set window of the day, for example 8am to 6pm.
ApoB
A blood test that counts the particles carrying cholesterol. Linked to heart disease risk.
Mitochondria
The parts of your cells that turn food and oxygen into energy.
Rapamycin, metformin
Prescription drugs that some experts take hoping to slow ageing. Not proven for that, and never part of your plan.
Medicine 3.0
Peter Attia's name for preventing disease early instead of treating it late.

Training splits are our estimates from each expert’s published routine. Following checked October 2026.

The key differences

  • Attia puts more of the week into strength: about 40% against 30%.
  • Patrick puts more of the week into intervals: about 30% against 10%.
  • Attia puts more of the week into mobility and stability: about 10% against 0%.
  • In plans in their style, both use 4-minute intervals (Norwegian 4 × 4) for hard sessions.
  • We rate the overall evidence behind both protocols as strong.
  • Supplements that go into a plan: Attia, omega-3; Patrick, omega-3, vitamin d with k2. Prescription items and personal stacks stay out of every plan.
  • Both include their own mobility or movement routine.

Protocols side by side

Each line is rated for the evidence behind it. “Doctor only” items never go into a plan.

Training

Peter Attia

  • Zone 2 cardio (a steady pace where you can still talk) about 3 hours a week, for example 4 × 45 min. Start with about 2 hours if new to itStrong evidence
  • VO2 max intervals: 4 min hard, 4 min easy, repeated 4–6 times, once or twice a weekSome evidence
  • Heavy strength training 3–5 times a week, focusing on grip, slow lowering, pulling and hip-hinge movementsStrong evidence
  • Stability and balance work woven into most daysSome evidence
  • Benchmarks such as carrying half your body weight in each hand for 1 minute (men; about 75% of that for women) and long dead hangsPersonal habit
  • Choose the physical tasks you want to manage at 100 and train toward them nowNote

Rhonda Patrick

  • At least 10 minutes of vigorous exercise a day; she suggests this should replace the 10,000-step goalSome evidence
  • Norwegian 4 × 4: four 4-minute intervals, hard but not all-out (the original protocol uses about 85–95% of max heart rate), with 3-minute recoveries, 1–2 times a week; build up graduallySome evidence
  • Keep daily walking too: step benefits level off around 6,000–8,000 steps a day for older adultsStrong evidence
  • Strength training at the start of most sessions, supported by enough proteinStrong evidence
  • Short 'exercise snacks' (e.g. 1 minute of squats or burpees) spread through the daySome evidence

Eating

Peter Attia

  • Protein at least 1.6 g per kg of body weight a day. About 2.2 g/kg is the better target for active people with healthy kidneysSome evidence
  • Spread protein across about four meals of roughly 40–50 gPersonal habit
  • Follows no named diet. Focuses on energy balance and avoiding junk foodNote
  • Doubts time-restricted eating as a general tool and saves longer fasts for specific patientsNote
  • Says alcohol has no biochemical benefit. Personally keeps it to 0–8 drinks a week, at most 2 a dayPersonal habit

Rhonda Patrick

  • Protein about 1.6 g per kg of body weight a day to support resistance trainingStrong evidence
  • Whole-food meals built on vegetables, berries and a protein source (eggs, fish, poultry, red meat)Personal habit

Supplements

Peter Attia

  • Fish oil reported at about 2 g EPA + 1.5 g DHA a day, aiming for a blood omega-3 level of about 8–12%Some evidence
  • Vitamin D, reported at about 5,000 IU a dayPersonal habit
  • Magnesium from several forms, about 1 g elemental a day in total (reported)Personal habit
  • Methylfolate and vitamin B12 to keep homocysteine below about 9 µmol/L, based on blood testsDoctor only
  • Prescription drugs such as statins or PCSK9 inhibitors to lower apoB when neededDoctor only
  • Treats rapamycin and metformin as unproven, experimental options, not general adviceNote

Rhonda Patrick

  • Omega-3 (EPA + DHA) about 2 g a day as a starting point; aim for an Omega-3 Index of 8% or more and retest after about 4 monthsSome evidence
  • Take omega-3 with a meal that contains fat; higher doses need care (bleeding risk, atrial fibrillation, medicines)Doctor only
  • Vitamin D with vitamin K2 in the eveningSome evidence
  • Creatine 10 g a day (her own dose, above the usual 3–5 g)Personal habit
  • Multivitamin, magnesium, nicotinamide riboside and PQQ as part of her personal stackPersonal habit

Sleep & recovery

Peter Attia

  • Allow 8–9 hours in bed with a fixed wake-up timeStrong evidence
  • Cool, dark bedroom, about 18 °CSome evidence
  • No food in the last three hours and no alcohol close to bedtimeSome evidence
  • Screens off well before bed. He keeps a second phone with no social appsPersonal habit
  • Sleep aids he has reported using: glycine, ashwagandha and magnesium L-threonate. Melatonin only for jet lagPersonal habit

Rhonda Patrick

  • Sauna 4–7 times a week, around 20 minutes at roughly 79 °C, based on Finnish cohort dataSome evidence
  • Schedule heat sessions a couple of hours before bedPersonal habit
  • After short sleep, vigorous exercise such as intervals or weights can help blood-sugar controlSome evidence
  • Cold exposure mainly in summer; she does not keep it up in winterPersonal habit

Stress & mind

Peter Attia

  • Treats emotional health as a pillar as important as physical healthNote
  • Journaling as a regular practicePersonal habit
  • Keeps social media off his evening phone to protect wind-down timePersonal habit

Rhonda Patrick

Brain health

Peter Attia

  • Regular dry sauna (Outlive cites about 4 × 20 min a week at 80 °C or more, linked in Finnish studies to lower dementia risk)Some evidence
  • Sees ketogenic eating as a possible alternative brain fuel in early cognitive decline, based on small trialsSome evidence
  • Says the benefit of vitamin D for dementia risk is unclearNote

Rhonda Patrick

  • Push hard enough to raise lactate: hard exercise raises BDNF, a growth factor linked to learning and mood (human evidence still early)Some evidence
  • Frequent sauna use is linked with lower dementia risk in Finnish men (observational)Some evidence
  • Keep omega-3 status up; she links it to brain health and ageing markersSome evidence

Weak spots to know

Peter Attia

  • Many of his exercise targets lean on observational studies that link fitness or strength to longer life. These show association, not proof that hitting a given number will add years.
  • A 2026 review in the Australian Journal of General Practice called the book's research base superficial. It said his intensive, personalised approach suits only a few affluent people, and that routine full-body MRI scans use a lot of resources and bring risks from incidental findings that the book does not discuss.
  • Some critics argue that the medications and screening tests he recommends for healthy people lack strong trial evidence, and that the risks could outweigh the benefits.

Rhonda Patrick

  • The sauna benefits she highlights come mainly from one observational cohort of middle-aged men in eastern Finland. It shows an association, not proof that sauna causes the benefit; women were not included, and commentators noted the reason for the link is unclear (heat, relaxation, lifestyle or social contact).
  • An epidemiology newsletter (The Edge of Epidemiology, 2025) argued that some of her headline numbers, such as vitamin D cutting dementia risk by about 40%, rest on observational studies and overstate what is known; genetic and trial evidence is mixed.
  • She often builds a case from biological mechanisms (e.g. lactate and BDNF, nutrients and serotonin). Several of these ideas are supported mostly by animal or small short-term human studies, as her own episodes acknowledge.
