Herman Pontzer & Burn: The Complete Guide
Constrained energy — exercise for health, not a free bakery pass
Burn (2021) is Pontzer’s Hadza-backed argument that 24-hour energy expenditure sits in a narrow band. More training does not linearly raise daily burn. This guide extracts the correction and sends you back to walking, Zone 2, and food — not a watch that ‘earned’ dessert.
Frequency
Daily movement plus boring food math
Duration
Years — compensation is not a 2-week hack
Level
Beginner
Key Takeaways
- 1Bodies compensate — the treadmill plus muffin usually fails
- 2Exercise anyway for capacity, glucose, and mood — not the calorie ring
- 3Weight change is still intake over months; this is not ‘calories don’t matter’
- 4Lieberman is why movement is weird; Pontzer is what it does to the budget

Constrained Energy
Moderate EvidenceHadza move for hours and do not burn a linear extra 1,000 kcal. Evolution spent the surplus elsewhere. Your watch is not a metabolic chamber.
Exercise Anyway
Strong EvidenceHealthspan, VO2, insulin, bone, mood. See Zone 2 and walking. Quitting training because ‘calories don’t increase’ is the wrong take-home.
Keep vs Skip
Moderate EvidenceKeep: steps, lifting, protein after 50. Skip: treating Burn as a fasting religion, and treating the watch as a dietitian.

Exercised (2021) is Lieberman’s evolutionary case that voluntary training is a modern invention. Humans evolved to walk, carry, and rest. This guide extracts the walking-first frame and sends you to Zone 2, Easter, and Starrett instead of a $4,000 treadmill.

Wearables & TrackersDaily Walking for Longevity: The Complete Guide
Walking is the highest-ROI movement habit in longevity medicine: lower all-cause mortality, better glucose control, and cognitive benefits — with zero equipment required. This guide separates step-count hype from structured Zone 2, and how wearables should track both.

Wearables & TrackersZone 2 Cardio: The Complete Guide
Zone 2 training, aerobic exercise at a conversational pace, is the most recommended longevity intervention by Peter Attia, Rhonda Patrick, and the longevity community. It builds mitochondrial density, improves metabolic health, and takes 3–4 hours per week. This guide covers heart rate zones, protocols, and tracking.

Cognitive EnhancementThe Obesity Code: The Complete Guide
The Obesity Code made intermittent fasting sound like endocrinology instead of willpower. The keepers are fewer snacks, fewer liquid sugars, and a daily eating window. The danger is fasting on glucose-lowering drugs without a clinician. This guide places Fung next to Longo and modern IF practice.

Metabolical (2021) is Lustig’s case that chronic disease is more foodable than druggable. Two rules: protect the liver, feed the gut. This guide extracts those rules and sends you to Bikman, Fung, Means, and Fiber Fueled — not a keto-vs-vegan flame war.

VO₂ max — the maximum rate at which you can use oxygen — is one of the best-studied predictors of all-cause mortality. Peter Attia calls it a vital sign. This guide covers lab testing vs wearable estimates, what 'good' looks like by age, and a training mix of Zone 2 plus intervals.
