Gabrielle Lyon vs Bryan Johnson

Gabrielle Lyon (physician (do)) and Bryan Johnson (entrepreneur, founder of blueprint) 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.

Words explained (12)
Zone 2
Steady cardio at a pace where you can still talk in full sentences, but not sing.
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.
Loaded carry
Walking while holding something heavy, like shopping bags or dumbbells.
Mobility
Moving your joints freely through their full range.
Leucine
A building block of protein that helps switch on muscle building. Meat, fish, eggs, dairy and soy are rich in it.
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.
Fibre
The part of plant foods you don't digest. It feeds healthy gut bacteria and keeps you full.
Time-restricted eating
Eating all your meals within a set window of the day, for example 8am to 6pm.
Glucose
Blood sugar.
Rapamycin, metformin
Prescription drugs that some experts take hoping to slow ageing. Not proven for that, and never part of your plan.

The key differences

  • Lyon puts more of the week into strength: about 60% against 30%.
  • Johnson puts more of the week into aerobic base (zone 2): about 40% against 20%.
  • In plans in their style, Lyon's hard sessions are 1-minute intervals; Johnson's are 4-minute intervals (Norwegian 4 × 4).
  • We rate the evidence behind Lyon's protocol higher: strong, against mixed for Johnson.
  • Supplements that go into a plan: Lyon, creatine monohydrate; Johnson, creatine monohydrate, omega-3. 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

Gabrielle Lyon

  • Resistance training 3–4 days a week, done with focusStrong evidence
  • 1–2 days a week of short, higher-intensity intervalsSome evidence
  • Steady aerobic work, such as a 30-minute session or a brisk walkStrong evidence
  • Move after meals: a walk, some air squats or a short bodyweight circuitSome evidence
  • For older adults who do nothing yet, any regular resistance training is the priorityStrong evidence

Bryan Johnson

  • About 150 minutes a week of moderate cardio (Zone 2, a pace where you can still talk)Strong evidence
  • About 75 minutes a week of vigorous work such as high-intensity intervalsStrong evidence
  • Strength training 3 times a weekStrong evidence
  • Balance, flexibility and mobility work included in the daily sessionSome evidence
  • 2–3 minutes of light movement every 30 minutes of sitting, plus two 10-minute walks a daySome evidence
  • He says even 20 minutes of exercise a day is worthwhile for people starting outNote

Eating

Gabrielle Lyon

  • About 2.2 g per kg of ideal body weight a day (she also gives 1.2–1.6 g per kg, sometimes up to 1.8 g per kg)Some evidence
  • 30–50 g of high-quality protein at the first meal, and a similar large dose at the last mealSome evidence
  • About 2.5 g of leucine (roughly 30 g of quality protein) per meal, and about 9 g of leucine across the daySome evidence
  • People eating mainly plants may need more total protein, around 1.6 g per kg, because plant protein is lower quality per gramSome evidence
  • For inactive people, about 130 g of carbohydrate a day, roughly 40–50 g per meal, with more after exercisePersonal habit
  • Older adults should avoid long fasts, which can speed muscle lossSome evidence

Bryan Johnson

  • About 2,250 kcal a day, which he describes as roughly 10% below his energy needsSome evidence
  • About 130 g protein a day, much of it from plant foods, protein powders and collagenPersonal habit
  • Lots of vegetables, legumes (black lentils, chickpeas), berries, nuts and extra-virgin olive oil (about 1 tbsp per meal)Strong evidence
  • All food eaten between about 5:30 am and noonPersonal habit
  • Stops drinking fluids at about 4 pm to avoid waking at nightPersonal habit
  • Follows no named diet; he says he avoids labels such as vegan or ketoNote

Supplements

Gabrielle Lyon

  • Creatine supports muscle; she mentions possible brain benefits at higher dosesSome evidence
  • Prefer complete protein foods over leucine alone; amino acid supplements make most sense when a meal is low in proteinNote
  • She regards the official leucine allowance (about 2.7 g a day) as too low because it was based on young menNote

Bryan Johnson

  • Creatine, 7.5 g a day in totalSome evidence
  • Omega-3 (EPA/DHA), 800 mg a daySome evidence
  • Fibre-type prebiotics (inulin, galacto-oligosaccharides, arabinogalactan) in his morning drinkPersonal habit
  • Ashwagandha and rhodiolaPersonal habit
  • Blueprint's own multi-ingredient capsules and antioxidant softgelsPersonal habit
  • Collagen powder; he suggests 20–30 g a day for skin and hairPersonal habit

Sleep & recovery

Gabrielle Lyon

No specific guidance in what we reviewed.

Bryan Johnson

  • Fixed early schedule: in bed about 8:30 pm, up about 4:30 amStrong evidence
  • Screens off and a 60-minute wind-down before bedSome evidence
  • No caffeine for 8–10 hours before sleepSome evidence
  • Bright light soon after waking and dim red or amber light in the eveningSome evidence
  • Dry sauna at about 79 °C for 20 minutes dailySome evidence
  • Tracks sleep with a wearable and aims for a very low resting heart rate before sleepPersonal habit

Stress & mind

Gabrielle Lyon

No specific guidance in what we reviewed.

Bryan Johnson

  • Uses a fixed routine so daily health choices do not depend on willpowerPersonal habit
  • Breathwork or reading as part of the evening wind-downSome evidence

Weak spots to know

Gabrielle Lyon

  • Her daily target of about 2.2 g per kg of ideal body weight is well above the official allowance of 0.8 g per kg and the 1.0–1.2 g per kg that an expert group recommends for over-65s; whether intakes that high add further benefit for most older adults is still debated.
  • The 'leucine threshold' idea behind her per-meal targets and her food rankings is contested; critics such as Simon Hill argue that total protein matters more and that well-chosen plant proteins can meet needs.
  • Some of the foundational research she draws on, such as Layman's 2005 study, was partly funded by beef and food industry groups.

Bryan Johnson

  • His results come from one person doing many things at once, so it is hard to tell which part works. Scientists including Nir Barzilai (Nature, republished by Scientific American, 2026), who said science can't rest on a single person, and Morgan Levine (quoted in Vice, reported by Lifespan.io, 2023) have made this point.
  • His 'speed of ageing' and biological-age figures come from epigenetic clocks and biomarker comparisons. Researchers such as Steve Horvath have noted that some of these clocks predict health outcomes less well than others, and none is yet proven as a measure of whether a treatment extends life.
  • Several therapies he has tried, such as young-donor plasma and rapamycin, he later dropped himself. The US FDA has warned that young-plasma infusions have no proven benefit and may cause harm.
