Bryan Johnson's Three Core Principles for Optimal Health
Its nice to have another 49 new Health & Tech legends here this week! ๐
Iโm in the perfect position to write thisโฆ ๐ I just spent an hour on the treadmill ๐โโ๏ธ, lifted in the gym ๐ช, had a Turkish-bread sandwich loaded with avocado, eggs & tomatoes ๐ฅ๐ , topped it off with some yogurt, and even got in a few hours of sleep ๐ด.
You might be wondering why Iโm laying out my workout and meals like some fitness nut? It is because today, Iโve done more to optimise my health than roughly two-thirds of people worldwide.
The WHO recommends at least 150 minutes of moderate-intensity exercise per week, which is about 21.5 minutes a day. Yet, less than one-third (30%) of us get the recommended activity levels.
We take supplements, probiotics, vitamins, and fish oils. Spend hours in saunas or taking cold plunges ๐ง, but we only need to master 3 things: Diet, Sleep, and Exercise.
This is according Bryan Johnson, the controversial tech entrepreneur who infamously spends over US $2 million/per year into his anti-aging programs.

Even though he follows 200+ daily interventions with a 30+ person medical team to fine-tune every biomarker, Johnson believes most of us should stick to just three pillars.
Now, a few of us can live that high-maintenance every day, but if youโre ever debating whether to add more supplements or biohacks to feel better or live longer, just double down on those three pillars first. Youโll get the biggest bang for your buck.
Diet
High-quality nutrition fuels everything from your mood to your longevity. When you focus on whole foods, you:
Dampen inflammation with antioxidant-rich berries & leafy greens ๐ฅฌ.
Regulate blood sugar by adding more fiber, which is great for anyone at risk of insulin sensitivity or diabetes ๐พ.
Pro tip: Swap carbs for whole grains and fill half your plate with veggies!
Sleep
Adequate sleep (generally 7โ9 hours for adults) is critical for brain function, immune defense, tissue repair, and hormonal regulation.
The chronic sleep deprivation has shown to increase the risks of cardiovascular disease, diabetes, and mental health disorders.
Aim for 7โ9 hours nightly. During deep sleep your brain:
Clears out โwasteโ for sharper memory & focus ๐ง
Balances stress & repair hormones โ๏ธ
Trains your immune defense so you bounce back faster ๐ก๏ธ
Wind-down ritual: Ditch screens 30 minutes before bed and try gentle stretches or reading ๐.
Physical Activity
Aim for 150 minutes/week of moderate activity (or 75 minutes vigorous):
Heart health: Lowers blood pressure & boosts circulation โค๏ธ
Metabolism: Improves insulin sensitivity & body composition ๐ฅ
Mind & mood: Releases endorphins to fight stress & anxiety ๐
Quick wins: Take brisk walks, hop on a bike, or try a 20-minute.
