Robert M. Sapolsky

Stanford neuroendocrinologist Sapolsky's definitive popular account of stress physiology. Covers the HPA axis, cortisol's circadian arc, chronic stress effects on immunity and metabolism, the testosterone–cortisol trade-off, and why psychological stressors never fully resolve. The clearest explanation of why the hormones module's lifestyle levers matter.

Justin Sonnenburg & Erica Sonnenburg

The accessible book from the Stanford Sonnenburg lab whose research underlies the module's gut-immune axis section. Covers how dietary fibre and fermented foods shape microbiome diversity, why modern diets deplete microbial richness, and practical dietary patterns for rebuilding a healthier gut. Pairs directly with the Wastyk 2021 trial and the Koh 2016 SCFA review.

Sean Carroll

Carroll argues that the Many-Worlds interpretation is the simplest and most straightforward reading of quantum mechanics, and that physicists have spent decades avoiding this conclusion. A rigorous but readable entry point into quantum foundations, written for curious non-physicists.

Jay Alammar & Maarten Grootendorst

A practical, visual book on how LLMs actually work and how to use them. Good follow-on if the "mental model" section made you want more.

Andrew Huberman, Matthew Walker, and many of the authors in this library have appeared as guests. One of the broadest-range shows for people interested in evidence-based self-improvement.

Mel Robbins

Practical, science-backed episodes on confidence, mindset, relationships, and habits. Mel Robbins is direct and actionable — less theory, more "do this today." A useful counterpart to longer-form shows when you want a concrete framework you can apply immediately.

Gollwitzer, P. M. & Sheeran, P.

The definitive meta-analysis (94 studies, 8,000+ participants) showing that specific "if-then" plans produce a medium-to-large effect on goal achievement (d ≈ 0.65) by shielding goals from distraction, temptation, and impulse. The scientific backbone behind structured habit planning.

Barber, B. M. & Odean, T.

Landmark Journal of Finance study on 66,000 households: average individual investors underperformed the market by ~1.5% per year; the most active traders lost ~6.5% annually relative to the index. The empirical case that undisciplined, high-turnover investing destroys wealth — and why a clear investment philosophy matters.

Koh, A., De Vadder, F., Kovatcheva-Datchary, P. & Bäckhed, F.

Cell 2016 review explaining how gut bacteria ferment dietary fibre into short-chain fatty acids (acetate, propionate, butyrate) and how these metabolites regulate host energy metabolism, immune function, and gut barrier integrity. The mechanistic backbone for why fibre diversity matters beyond simple "roughage" advice.

Cohen, S., Doyle, W. J., Alper, C. M., Janicki-Deverts, D. & Turner, R. B.

Archives of Internal Medicine, 2009. 153 healthy adults were exposed to rhinovirus after two weeks of documented sleep monitoring.

One of the clearest controlled demonstrations that sleep duration directly regulates immune defence.

Leproult, R. & Van Cauter, E.

JAMA, 2011. Healthy young men restricted to 5 hours' sleep per night for one week showed a 10–15% decline in daytime testosterone, equivalent to 10–15 years of normal ageing. The controlled study behind the hormones module's sleep–testosterone claim and one of the clearest demonstrations that sleep directly regulates hormone output.

Richter, E. A. & Hargreaves, M.

Physiological Reviews, 2013. Comprehensive review of how muscle contractions translocate GLUT4 transporters to the cell membrane, enabling insulin-independent glucose uptake during and after exercise. The mechanistic basis for the hormones module claim that a short walk after eating can reduce the blood glucose peak without requiring additional insulin signalling.

Wastyk, H. C., Fragiadakis, G. K., Perelman, D. et al.

Cell, 2021. Randomised controlled trial from the Sonnenburg lab at Stanford (n=36) comparing a high-fibre diet against a high-fermented-food diet over 17 weeks. The fermented food arm showed increased microbiome diversity and significantly reduced levels of 19 inflammatory proteins. The study directly behind the module claim about daily fermented food intake.

Furman, D., Campisi, J., Verdin, E. et al.

Nature Medicine, 2019. Definitive review (30 co-authors, Stanford and Buck Institute) mapping how chronic low-grade inflammation drives cardiovascular disease, cancer, type 2 diabetes, Alzheimer's disease, and depression. Identifies modifiable lifestyle factors — diet, sleep, stress, physical activity — as the primary levers for reducing systemic chronic inflammation.

Ridker, P. M., Everett, B. M., Thuren, T. et al.

New England Journal of Medicine, 2017. The CANTOS trial (n=10,061).
