Dave Asprey: “Laziness can make you stronger”

Dave Asprey is not a man like the others. At 52, this Silicon Valley entrepreneur claims to have the biological age of a thirty-year-old. His secret? Having spent over a million dollars and twenty years of his life hacking his own body. From coffee to butter enriched with medium-chain triglycerides (MCT) that he popularized around the world, through the hundreds of protocols tested in his “human upgrade laboratories”, Dave Asprey has created a real movement around biohacking. His latest book, Hyper health (Thierry Souccar editions), released in French on December 4, 2025, details the ways to be healthier and stronger by relying on a counter-intuitive principle: laziness can become our greatest ally.

The World of Nutrition: Your book is called Hyper health in French. Why this provocative title?

Dave Asprey : Because we have it all wrong from the start! For decades we have been told that hard work is the path to progress. But the truth is, if you have to work hard all the time, then you’re bad at your job. I’m serious! Our brains are lazy – they are constantly trying to save energy to stay alive. Instead of fighting this natural tendency, we should use it to our advantage.

You talk about the “laziness principle”. Can you explain this concept to us?

This is the central idea of ​​the book. Your body is programmed to be lazy – it’s a trait, not a bug! This laziness allowed our ancestors to survive by saving energy. The problem is that we are constantly trying to combat this laziness with willpower. Result ? We fail. My approach is different: accept that you are lazy, and use that laziness as leverage. Instead of doing 45 minutes of cardio, do 10 minutes of smart effort that delivers six times the results. This is what I call the “biology of the slope of the curve.”

Your body is programmed to be lazy

How does this work in practice?

Let’s take exercise. Most people spend 30 to 45 minutes doing cardio at 70% of their maximum capacity. It’s inefficient and exhausting. The approach that I propose in Hyper healthit’s REHIT – Reduced Exertion High-Intensity Training. You go at 100% capacity for just a few seconds, then you let your body adapt. The secret is adaptation, not prolonged effort. You get six times the cardiovascular benefits in one-sixth the time. It’s the same for everything: diet, meditation, recovery. You have to create an intense signal peak, then let the body do its work.

You even say that exercising too much is counterproductive.

Exactly ! I only exercise 20 minutes a week using AI, and I keep myself at about 6% body fat. The problem with traditional exercise is that it depletes your energy without ever getting your body to the peak intensity where real improvement occurs. This is a huge waste! Our nature goes against exercise as we practice it today.

You talk at length about the key role of mitochondria, these small energy plants present in our cells.

You’re not in charge, your mitochondria are. Aging is nothing more than mitochondrial dysfunction. Hence the importance of optimizing their function through exposure to cold, red light, minerals, and even compounds like methylene blue which act as “starter cables” for tired mitochondria.

Let’s talk about Bulletproof Coffee, the drink you made famous. How was this idea born?

The inspiration came to me during a high altitude expedition near Mount Kailash in Tibet, at 5,600 meters above sea level in -10°C. A petite Tibetan woman offered me a cup of hot yak butter tea. Instantly, I felt alive again! Back home, I wanted to recreate this effect. I replaced yak butter with butter from grass-fed cows, tea with mold-free coffee, and added MCT (medium-chain triglycerides) oil to boost brain and energy. The results were extraordinary!

You put a lot of emphasis on mold in coffee. For what ?

Most coffee beans are contaminated with toxic mold that attacks your mitochondria and disrupts your brain. Even Joe Rogan rolls his eyes when I talk about it! But it is scientifically proven. This is why I sell mold-free coffee. People think it’s just marketing, but the reality is that coffee quality has a massive impact on your health. Mold hides everywhere – in walls, air ducts, furniture – and your body reacts even if you don’t see it.

In Hyper healthyou propose numerous and very concrete protocols. Can you give us some examples of easy-to-implement hacks?

Of course ! Here are some of my favorites that cost little to nothing.
1. Exposure to cold: end your shower with 30 seconds of cold water. This activates brown fat, stimulates mitochondria and boosts energy.
2. Breathing: Five minutes of controlled breathing can shift your nervous system from “fight or flight” mode to “rest and recovery” mode. It’s free and accessible to everyone.
4. Exposure to light: avoid blue light in the evening, expose yourself to red light. Your brain receives the constant “it’s daytime” signal every five seconds from screens, which disrupts your circadian rhythm and turns you into a zombie.

Some critics accuse you of selling dreams or even expensive products. What do you answer them?

I understand the skepticism. Yes, I sell products – yellow-tinted glasses that protect against “unwanted light,” stickers to cover device lights, neurotraining retreats for $15,000 for five days. But everything I recommend, I use myself. I have invested over a million dollars testing these technologies on my own body. What’s important is that many of my best tips are free or inexpensive. Breathing, cold, smart exercise – all this costs nothing. Advanced technologies are for those who want to go further, faster.

In Hyper healthyou also talk about spiritual biohacking. What do you mean by that?

Biohacking isn’t just about optimizing your metabolism and hormones. It is also the art and science of changing your environment, outside and inside you, to have total control of your own biology. This includes the spiritual dimension. Before trying spiritual biohacking, it’s essential to have your energy up and the fundamentals in place. I offer three steps to spiritual recovery – it’s the antidote to spiritual stress that can result from a breakup, loss of a job, or a serious accident. You are shaken, and you need to detoxify. Compassion and empathy are an integral part of biohacking. The highest level, according to Buddhism, is equanimity – when you can meditate in the middle of a storm and choose your state.

What are your three essential tips for someone starting out in biohacking?

Excellent question!
First, improve your brain and body for high performance. Energy is your most precious resource. Without energy, nothing else is possible.
Second, practice “strategic laziness” – prioritize the things only you can do. If someone else can do it, delegate. This frees up time and energy for what really matters.
Third, take risks, but take risks that have returns greater than the risk you are taking. This is how you build something extraordinary.
