Today, Dave Asprey is well-known as one of the leading figures of the biohacking movement and the founder of the Bulletproof empireif you've ever put butter in your coffee, he's the reason why. But it wasn't always this way: In his 20s, he was working as a computer hacker while tipping the scale at around 300 pounds. He was fed up with feeling awful all of the time and dealing with arthritis and chronic fatigue. Despite doing all of the standard right things his doctors advised, including exercise and counting calories, he was stuck.

So he began experimenting himself, first with a low-carb diet that resulted in a 50-pound weight loss. From there, he was hooked. So hooked that Asprey says he has spent more than $1 million building a better body, experimenting with everything from red light therapy to cold exposure, with the goal to live until at least 180.

Last week, The New York Times bestselling author released his latest, Fast This Way, which reviews the latest thinking on how to turn eating restrictions into better health. GQ chatted with Asprey to find out what his day-to-day looks like while running his business from a 32-acre organic farm on Vancouver Island, off Canada's Pacific Coast. It indeed involves fasting and drinking coffee with butter in itbut also the occasional bite of dairy-free ice cream.

For Real-Life Diet, GQ talks to athletes, celebrities, and everyone in between about their diet, exercise routines, and pursuit of wellness. Keep in mind that what works for them might not necessarily be healthy for you.

GQ: What time do you usually get out of bed?

Dave Asprey: I usually get out of bed around 6:45 or 7 a.m. I used to go to bed much later and wake up later, but it's just less convenient. So I used a combination of light and fasting to shift my circadian windows. Now, I go to bed earlier than I ever have in my life. And I do it naturally, which is super cool.

I wake up, and I definitely make a shot of espresso. I usually turn that into an Americano. I also make one for my wife and one for my kids to split because yes, my kids do drink coffee. It's good for you. It's a superfood, screw kale. Sometimes I make it Bulletproof (using MCT oil and grass-fed, unsalted butter). Others, I just do a black, depending on what I feel like for the day.

Talk to me about your morning supplementsI've seen the photos, and there are a lot of them.

I take a handful of the supplements that I put together the night before that are mostly mitochondrial stimulators or other anti-aging things, peptides, etc. We're talking like 40 or 50 pills. Some of them are ones that I formulated for Bulletproof. I also take all of my probiotics in the morning when I wake up, because I have found in recent research that if you take probiotics at night, they disrupt your sleep. If you take them in the morning they seem to work better. I usually take some prebiotic fiber at some point, which feeds the good bacteria. My goal lately has been to make bacteria in my gut the manufacturer of as many of the things that I want in my body as possible. I also take all my minerals and stuff like that.

[In a follow-up email, Asprey clarified that his current morning supplement lineup includes, from Bulletproof, vitamins A, D, and K, glutathione, Eye Armour, copper and zinc, and Smart Mode, along with amino acids and calcium d-glucarate.]

Anything else thats important to your morning routine?

When I wake up, I do just a brief gratitude practice. I just lay there for a minute or two and I have two things that I'm grateful for. One is that I say to no one in particular, Thank you for using me today. I don't say what for, I'm just going to assume things work out the way they're supposed to happen. The second gratitude is, Thank you for making things happen the way they're supposed to happen.
