Words explained (9)
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.
Hypertrophy
Muscle growth.
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.
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.

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

The key differences

  • Norton puts more of the week into strength: about 65% against 30%.
  • Chatterjee puts more of the week into aerobic base (zone 2): about 50% against 25%.
  • In plans in their style, both use 1-minute intervals for hard sessions.
  • We rate the evidence behind Norton's protocol higher: strong, against solid for Chatterjee.
  • Supplements that go into a plan: Norton, creatine monohydrate, whey protein, caffeine before training; Chatterjee, none (food first). Prescription items and personal stacks stay out of every plan.
  • Only Chatterjee has a mobility or movement routine of their own.

Protocols side by side

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

Training

Layne Norton

  • Lift weights consistently, year after year, and take sets close to failureSome evidence
  • Exercise improves health markers even when it does not change your weightStrong evidence
  • Track daily steps while dieting: everyday movement tends to drop as calories fallSome evidence
  • His PHAT programme: 5 days a week, two heavy 'power' days plus three higher-rep hypertrophy daysPersonal habit

Rangan Chatterjee

  • Walk at least 10,000 steps a daySome evidence
  • Strength training twice a weekStrong evidence
  • Short daily glute exercises (e.g. hip extensions), a couple of minutesPersonal habit
  • Five-minute home workout: five moves back to back, 20 s on / 40 s off for beginners or 40 s on / 20 s off for advanced, five roundsSome evidence
  • Swap any move that is too hard, painful or unsafeNote

Eating

Layne Norton

  • Track calories and protein; food labels can be ~20% off, but consistent tracking still shows your true intake over timeSome evidence
  • Weigh yourself each morning and compare weekly averages, not single daysSome evidence
  • Protein about 1.6 g/kg a day; up to ~2.2 g/kg when dieting or very leanStrong evidence
  • Choose a diet style you can sustain; low-carb and low-fat work equally well with calories and protein matchedStrong evidence
  • Fibre about 15 g per 1,000 kcalSome evidence
  • Seed oils are fine: replacing saturated fat with polyunsaturated fat lowers LDL and heart riskSome evidence

Rangan Chatterjee

  • Eat within a 12-hour window (for example 8am to 8pm), leaving about 12 hours a day without foodSome evidence
  • Five portions of different vegetables every dayStrong evidence
  • Around eight glasses of water a dayPersonal habit
  • Eat at least one meal a day at a table, with no phone or device nearbyPersonal habit
  • No fixed protein target in the sources we checkedNote

Supplements

Layne Norton

  • Tier 1 – creatine monohydrate 3–5 g a day; loading is optional; timing does not matterStrong evidence
  • Tier 1 – whey protein 20–40 g per serving (about 2–3 g leucine) to help reach daily proteinStrong evidence
  • Tier 1 – caffeine 3–6 mg/kg about 45–60 min before training; lower doses still help alertnessStrong evidence

Rangan Chatterjee

No specific guidance in what we reviewed.

Sleep & recovery

Layne Norton

  • Avoid caffeine late in the day; it can harm sleep even if you fall asleep normallyStrong evidence
  • Carb timing matters little on average; if carb-heavy meals make you sleepy, move themNote
  • Poor sleep and unmanaged stress are bigger problems than small nutrition detailsNote

Rangan Chatterjee

  • A tech-free wind-down before bed, ideally about 90 minutesSome evidence
  • Set a cut-off for work email in the evening (e.g. 8–8:30pm)Personal habit
  • Avoid emotionally charged topics, such as money worries, late in the eveningPersonal habit
  • Get daylight or time in nature in the morning, even five minutes, to help set the body clockSome evidence

Stress & mind

Layne Norton

No specific guidance in what we reviewed.

Rangan Chatterjee

  • A daily stillness practice, starting with two minutes of meditationSome evidence
  • 3-4-5 breathing: in for 3, hold for 4, out for 5, for about five minutesSome evidence
  • One full screen-free day a weekPersonal habit
  • Before bed, write down three things that went well and whySome evidence
  • Five minutes a day enjoying natureSome evidence

Weak spots to know

Layne Norton

  • Commercial ties: he co-founded Outwork Nutrition, which sells whey protein and products containing creatine — overlapping with his Tier 1 list — and co-founded the paid Carbon Diet Coach app and the BioLayne coaching business. He has also disclosed past research funding from the National Dairy Council, the National Cattlemen's Beef Association and the Egg Board.
  • Reverse dieting, which he helped develop and popularise, had no published controlled trials supporting it as of 2021; its use rests mainly on coaching experience.
  • His relaxed view of seed oils is contested by others in the health space. On The Drive (2026), Peter Attia presented the strongest case against seed oils for a debate after the booked guest declined, while saying his own view is close to Norton's; debate continues over older trials and LDL oxidation.

Rangan Chatterjee

  • The 4 pillar approach is broad, sensible lifestyle advice, but the evidence behind specific claims is mixed; for example, a large trial found a daily eating window added no significant weight loss on top of cutting calories.
  • Some targets are round rules of thumb rather than research-based numbers: the 10,000-step goal is higher than where the benefit levels off for people over 60 (about 6,000–8,000), and eight glasses of water a day is a convention, not a tested target.
  • He has commercial ties alongside his health advice: books, an app and a paid community, and since 2023 an advisory role with Levels, a glucose-monitoring company.
