Andrew Huberman (neuroscientist) and Rangan Chatterjee (doctor, former nhs gp) 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.
Training splits are our estimates from each expert’s published routine. Following checked October 2026.
The key differences
Huberman puts more of the week into strength: about 45% against 30%.
Chatterjee puts more of the week into aerobic base (zone 2): about 50% against 40%.
In plans in their style, Huberman's hard sessions are short sprints; Chatterjee's are 1-minute intervals.
We rate the evidence behind Chatterjee's protocol higher: solid, against mixed for Huberman.
Supplements that go into a plan: Huberman, omega-3; 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

Weak spots to know
Andrew Huberman
Supplements: Jonathan Jarry of McGill University's Office for Science and Society (2023) argued that he promotes supplements most people do not need. He said herbal products such as tongkat ali, Fadogia agrestis and shilajit are poorly studied, and that the evidence for some claims, such as myo-inositol for sleep and anxiety, is weaker than presented.
Sponsorships: the podcast is funded by sponsors that include supplement, testing and wellness companies. He became AG1's paid scientific advisor in 2022, and past sponsors named by critics include InsideTracker, Thorne and Momentous. Critics say this creates a financial incentive. Neuroscientist David Berson has praised the podcast but said some researchers disapprove of certain sponsorships and supplement promotion.
Certainty and extrapolation: scientists including cancer biologist Joseph Zundell and immunologist Andrea Love (Slate, 2024) say he sometimes applies animal or small human studies to everyday advice and speaks outside his field. New York Magazine (2024) said he presents certainty where the science is unclear. For example, the widely quoted dopamine rise from cold comes from a small 2000 study of an hour in 14 °C water, far longer than the short dips he suggests.
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.
