Words explained (7)
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.
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.
Mitochondria
The parts of your cells that turn food and oxygen into energy.

Background

Rhonda Patrick studied biochemistry and chemistry at the University of California, San Diego. She earned a PhD in biomedical science through the University of Tennessee Health Science Center, doing her research at St. Jude Children's Research Hospital in Memphis on mitochondria, cell death and cancer.

After her PhD she did postdoctoral work with the biochemist Bruce Ames at Children's Hospital Oakland Research Institute. There she studied how shortfalls in vitamins and minerals affect metabolism, inflammation, DNA damage and ageing, and wrote papers on how vitamin D and omega-3 fats may influence serotonin in the brain. She also did ageing research at the Salk Institute.

She became widely known through FoundMyFitness, her website, podcast and YouTube channel, and through many long guest appearances on The Joe Rogan Experience. Her topics include micronutrients, exercise, fasting, and 'hormetic' stressors such as sauna, heat and cold.

Today she runs FoundMyFitness, which is funded largely by paid premium members who get a private podcast, live Q&A sessions and a research newsletter. She is also listed as an associate scientist and board member of the Fatty Acid Research Institute.

Core ideas

  1. Exercise intensity matters, not just step counts: a short dose of hard effort each day adds benefits that easy walking does not.
  2. A high VO2 max (aerobic fitness) is one of the strongest signs of long life, so it is worth training on purpose.
  3. Short, controlled stressors such as sauna heat and hard exercise trigger repair processes that may slow ageing.
  4. Many people are low in key nutrients such as omega-3 fats and vitamin D, and testing can show whether you need more.
  5. Muscle is worth protecting with resistance training and enough protein, around 1.6 g per kg of body weight.
  6. What happens in muscle affects the brain: hard exercise releases signals such as lactate that may support memory and mood.

How Patrick lives

In a 2025 FoundMyFitness episode she described her routine when at home: about five hours of exercise a week, heat sessions most evenings, protein at every meal and a set of morning and night supplements.

~5 h
exercise a week (reported)
~3 h
CrossFit-style sessions a week
~5
evenings a week in sauna or hot tub
~1.6 g/kg
daily protein target
  1. MorningEggs, avocado and a kale and blueberry smoothie; multivitamin, 10 g creatine, omega-3 and a cocoa flavanol supplement.
  2. Training daysCrossFit-style session: strength work first, then intervals or cardio such as rowing, cycling or sprints.
  3. Recovery daysRunning, which she says helps clear her head; short 'exercise snacks' such as a minute of squats or burpees.
  4. LunchOften a homemade turkey burger.
  5. DinnerA large salad or vegetables with chicken, salmon, turkey or red meat.
  6. EveningSauna or hot tub (she alternates) a couple of hours before bed; magnesium, more omega-3, vitamin D, vitamin K2 and nicotinamide riboside.

The protocol

Training

  • 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

  • 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

Go deeper: Eating (Tim Spector, Chris van Tulleken)

Supplements

  • 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

  • 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

Go deeper: Sleep (Matthew Walker, Colleen Carney)

Brain health

  • 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

Patrick’s style in your plan

Choose “Follow one expert” and we keep this balance of training and the methods above, then fit them to your age, your available time and your health screen.

What we adapt

Session length and number to your week. Loads start from your self-tests, never a one-rep max. Hard sessions never on back-to-back days.

Never in your plan

Anything marked “Doctor only”: prescriptions, and doses set by blood tests. We show these as their choice, not as advice.

You can mix

Prefer someone else’s eating or sleep advice? Pick one expert per area and set your own strength-cardio balance.

The research behind it

Sauna and death from heart disease

Finnish men who used a sauna 4–7 times a week had about half the risk of fatal heart disease of once-a-week users over about 20 years.

Laukkanen et al., JAMA Internal Medicine, 2015

Sauna and dementia

In the same Finnish cohort, men using a sauna 4–7 times a week had about 66% lower risk of dementia than once-a-week users.

Laukkanen et al., Age and Ageing, 2017 (online Dec 2016)

Reversing a stiffening heart

Two years of supervised training that included high-intensity intervals raised VO2 max by 18% and reduced heart stiffness in sedentary adults in their early 50s.

Howden et al., Circulation, 2018

Short bursts of vigorous activity

Adults who did no formal exercise but had brief bouts of vigorous daily activity had lower risk of death.

Stamatakis, Ahmadi et al., Nature Medicine, 2022

Honest about weak spots

  • 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.
  • Her personal supplement stack is long and includes products with little outcome evidence (e.g. nicotinamide riboside, PQQ). FoundMyFitness is funded by paid memberships, and she sits on the board of the Fatty Acid Research Institute while promoting omega-3 index testing.

Where experts disagree

  • Creatine dose: Patrick takes 10 g a day herself; Layne Norton recommends 3–5 g a day for maintenance.
