The Guy Who’s Treating His Body Like a Science Project
Bryan Johnson is a tech entrepreneur who sold his company for hundreds of millions of dollars and then decided to spend his time and money trying to slow biological ageing. Not metaphorically. Literally.
His life is tracked through constant blood tests, imaging, sleep data and nutritional analysis. His project, known as Blueprint, has been covered by major media outlets because it pushes the limits of modern nutrition and health science.
This is not someone eating whatever feels good.
This is someone eating whatever performs best.
Which is why his food choices are interesting, even if his lifestyle is extreme.
So Why Do Macadamias Keep Appearing On His Plate
Among the carefully selected foods in Bryan Johnson’s diet, macadamia nuts appear consistently.
Not because they are fashionable.
Not because they are indulgent.
But because of their fat profile.
Across published diet breakdowns, interviews and third-party analyses of the Blueprint protocol, macadamias are highlighted as a preferred fat source due to their exceptionally high monounsaturated fat content and very low omega six levels compared to most nuts and cooking oils.
When someone that data-driven chooses a food repeatedly, it is usually because it behaves well in the body.
The Fat Science Bit Without Making Your Eyes Glaze Over
Macadamias are unusually high in oleic acid, the same monounsaturated fat often praised in olive oil. At the same time, they are extremely low in omega six linoleic acid.
Why does that matter?
Modern diets already contain large amounts of omega six fats, mostly from processed seed oils. When consumed in excess, omega six fats can push inflammatory pathways in the wrong direction. This is well established in mainstream nutritional research.
Peer-reviewed studies published in journals such as The Journal of Nutrition have shown that diets rich in macadamias can improve cholesterol profiles, lower LDL levels and maintain HDL without increasing markers associated with inflammation.
In simple terms, macadamias deliver energy without unnecessary metabolic stress.
What This Means If You’re Not Trying To Live Forever
Most people are not running longevity experiments on themselves. They simply want to eat well, feel good and avoid making things harder on their bodies over time.
That is where Bryan Johnson’s macadamia choice becomes useful rather than intimidating.
The takeaway is not to copy his lifestyle.
It is to understand the logic behind one decision.
Choose fats that quietly support your body rather than fight it.
Why Macadamia Oil Is The Everyday Shortcut
Eating whole macadamia nuts daily is not practical for most households.
Cooking with macadamia oil is.
Cold pressed, unrefined macadamia oil carries the same fatty acid composition as the nut itself, but in a form that fits seamlessly into everyday cooking. You do not need to change recipes or eat differently. You simply change the oil.
Roast vegetables, grill seafood, dress salads or cook proteins and you apply the same fat logic used in longevity focused diets, without turning your kitchen into a laboratory.
We explore how this works in practice in how macadamia oil behaves in everyday cooking.
No Extremes Required
This is not about biohacking.
It is not about copying a billionaire.
And it is not about chasing health trends.
It is about recognising when someone operating at the edge of science chooses something simple and asking why.
Macadamias are native.
They are structurally sound nutrition.
Macadamia oil simply makes that benefit usable in real life.
Sometimes the smartest health upgrades are the ones you barely notice once they become routine.
