Build a plan from bothSee the protocols
Words explained (10)
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.
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.
Polyphenols
Natural plant compounds in foods such as berries, tea, coffee, cocoa and olive oil.
Time-restricted eating
Eating all your meals within a set window of the day, for example 8am to 6pm.
Mitochondria
The parts of your cells that turn food and oxygen into energy.

The key differences

  • Patrick puts more of the week into aerobic base (zone 2): about 40% against 25%.
  • Hyman puts more of the week into mobility and stability: about 15% against 0%.
  • In plans in their style, Patrick's hard sessions are 4-minute intervals (Norwegian 4 × 4); Hyman's are 1-minute intervals.
  • We rate the evidence behind Patrick's protocol higher: strong, against mixed for Hyman.
  • Supplements that go into a plan: Patrick, omega-3, vitamin d with k2; Hyman, protein shake with creatine after training, omega-3 fish oil. 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

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

Mark Hyman

  • Strength training 3–4 times a week, about 30 minutes, mainly resistance bands and moderate weightsStrong evidence
  • Aerobic or interval training 4–6 days a week, about 30 minutes (cycling, tennis, hiking, swimming)Strong evidence
  • Yoga a couple of times a week plus a little stretching most daysSome evidence
  • Avoids very heavy lifting as he ages to limit injury riskPersonal habit
  • Hypoxia (low-oxygen) training with a machine or maskPersonal habit

Eating

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

Mark Hyman

  • Pegan diet: about 75% of the plate from plants, mostly non-starchy vegetablesStrong evidence
  • Cut sugar, refined flour and ultra-processed foodsStrong evidence
  • 1–2 cups of cruciferous vegetables (broccoli, cabbage etc.) a daySome evidence
  • Healthy fats from olive oil, avocado, nuts, seeds and small oily fishStrong evidence
  • Avoid gluten and most dairy, even without intolerancePersonal habit
  • Daily overnight fast of 12–16 hoursSome evidence

Supplements

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

Mark Hyman

  • Protein shake after training: 30–50 g whey (goat) plus 5 g creatineStrong evidence
  • Vitamin D, fish oil, a multivitamin and magnesium at nightSome evidence
  • NMN (about 900 mg a day), urolithin A, quercetin, curcumin and similar 'longevity' compoundsPersonal habit
  • His own branded gut supplement (prebiotics, probiotics, polyphenols)Personal habit

Sleep & recovery

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

Mark Hyman

  • 7–8 hours of sleep with a regular bedtime around 10 pmStrong evidence
  • Dark, quiet bedroom with eye mask and earplugsSome evidence
  • Blue-light-blocking glasses in the eveningPersonal habit
  • Steam or sauna and cold plunge most daysPersonal habit
  • Red light therapy at homePersonal habit

Stress & mind

Rhonda Patrick

No specific guidance in what we reviewed.

Mark Hyman

  • Meditation once or twice a day plus breathworkSome evidence
  • As much time in nature as possibleSome evidence
  • Regular time with friends and familySome evidence
  • Regular massagePersonal habit

Brain health

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

Mark Hyman

No specific guidance in what we reviewed.

Weak spots to know

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.

Mark Hyman

  • Functional medicine as a field lacks randomised trial evidence; surgeon and blogger David Gorski (Science-Based Medicine, 2014; Respectful Insolence, 2019) argues its useful parts (diet, exercise, sleep) are not unique and its unique parts (broad testing, supplements, 'detox') are not proven.
  • A 2021 Red Pen Reviews analysis of Eat Fat, Get Thin scored its scientific accuracy 1.2 out of 4, finding the claim that saturated fat does not cause heart disease conflicts with most controlled studies.
  • Commercial ties are large: he co-founded and is chief medical officer of Function Health (direct-to-consumer lab testing) and sells supplements through his own online shop; nutrition scientist Adrian Chavez (Katie Couric Media, 2026) noted one of his supplement stacks supplies 7,000 IU of vitamin D a day, above the usual 4,000 IU upper limit.
