Today’s medical and pharmacological systems have been successful in responding to trauma — reducing childhood mortality and fatalities from any number of catastrophes.
But as we live longer, more of us face chronic diseases that need more prevention, sometimes decades before any given catastrophe. That’s “Medicine 3.0,” and before the systems ever get an overhaul, there are lessons for us. Improve not just life span, but health span.
That’s the argument of the popular 2022 book “Outlive: The Science and Art of Longevity” by physician and longevity expert Dr. Peter Attia. It’s no fad diets or quirky health plans. It’s a bit more like a contribution to health like what economist Emily Oster did for pregnancy — ripping through research to piece together a more commonsense and modern approach to the world.
Below I share a few changes I’m trying to incorporate into my lifestyle and other notes from the book.
The basics are all here: the importance of exercise, especially strength training; nutrition; emotional health; advanced screenings and sleep.
For exercise, he writes about different intensity levels, and he recommends an 80/20 split in a given week between low intensity (Zone 2) and high-intensity (Zone 5), in which you can’t easily hold a conversation. Strength training in particular should not be overlooked.
For nutrition, beyond prioritizing whole foods (few prepackaged and processed ones), he notes there are only three approaches: Direct caloric restriction (how much you eat); dietary restriction (what you eat); time restriction (when you eat).
How do I put it all together for my own lifestyle changes:
- Bicycle commuting 2-3 times a week (Zone 2)
- Attempt weekly pickup basketball (Zone 5)
- Run with the kids more!
- Daily pushups, squats and eventually return to weightlifting (strength training)
- Nutrition: Return often to meal tracking for “direct caloric restriction”
- Sleep: Go to bed by 10:30pm, with lights out by 11pm
- Emotional Health: friendships and hobbies and meaning and lifestyle (But I should be more meditative, thankful and reflective, to give myself a break more often)
- Advanced Screening: Keep up those annual checkups!
- Leg stands when I brush my teeth, because apparently that is a thing
A few other, more general notes from the book more generally:
- His recommendation is to focus on improving health in your “marginal decade”
- My decathaon at age 100
- Every time you brush your teeth, stand on just one leg for at least 30 seconds and then alternate
- Importance of leg stands: In a 2022 British Journal of Sports Medicine cohort (age 51-75), people who could not hold a 10-second one-leg stance were 84 % more likely to die from any cause over the next decade—even after adjusting for age, BMI and co-morbidities
- His focus is the “minimum effective dose” — what time, effort and exertion has the most effective health impact
- I’m supposed to know my ApoB concentration level in my blood
- Medicine 3.0 — treat the trajectory, not the catastrophe
- He argues that today’s “Medicine 2.0” waits for disease to bloom, then tries to patch it. His Medicine 3.0 flips the goal to preventing the four big killers decades earlier with individualized metrics: heart disease, cancers, metabolic disease like diabetes and brain-degeneration like Alzheimer’s and Parkinson’s
- In practice, this means acting on risk curves in your 40s—or sooner—rather than accepting “normal” age-based averages.
- Instead of generic longevity goals, Attia recommends we list ten physical tasks we still want to perform at 100—then “back-cast” training so you arrive there capable. This framework reframes workouts as a lifelong skills budget: bank strength, balance, and aerobic capacity now, because each declines ~1 % per year after mid-life. The real target is your final ten years (“marginal decade”), when quality of life separates sharply according to earlier preparation.
- Focus on the Four Horsemen: He concentrates on the chronic-disease quartet responsible for >80 % of deaths over age 50: atherosclerotic disease, cancer, neurodegeneration, and metabolic dysfunction/type 2 diabetes.
- Every pillar—exercise, nutrition, sleep, emotional health, advanced screening—is judged by how well it delays or blunts these four trajectories. This keeps the program ruthlessly priority-driven instead of fad-driven.
