Who is Ben Greenfield?

Ben Greenfield is an American health coach, author, public speaker and podcaster.

He is renowned as being one of the leading ‘biohackers’ around and he has gained a loyal following thanks to the extreme measures he goes to in order to optimise his health.

Ben, who is the author of an impressive 13 books, describes himself as a “human performance consultant”.

Ben was born on 20 December 1979 in Lewiston, Idaho. He was homeschooled K-12 and he admits that the experience forced him to be very self-dependent.

His father was former firefighter and paramedic, who later became an entrepreneur.

“I had to be completely independent and very self reliant all through education,” Ben explains. “I actually enjoy the solitude, working alone, being solo, being a lone wolf.”

Ben graduated aged 15 and began college at 16 years old, playing singles and doubles for the men’s tennis team.

“I continued to teach tennis lessons all the way up through my freshman year of college. I also ran a private job as a writing tutor for high-schoolers.”

As a youngster, Ben was regularly on antibiotics because of a number of digestive issues, which possibly explains his fascination for good health.

He studied anatomy, physiology, biomechanics, pharmaceuticals, microbiology, biochemistry and nutrition. He then completed an internship at Duke University and the National Football League.

He graduated in 2004 aged 20, as the top senior in his class at University of Idaho.

In 2005, Ben began to move into the fitness industry. He partnered with physicians and opened up personal training studios, gyms, and physiology and biomechanics labs across northern Idaho and eastern Washington.

A few years later, in 2008, Ben was voted as America’s top personal trainer.

It was during his initial years in the fitness industry that Ben began to compete as an amateur triathlete. He ended up completing more than 120 races and 12 Ironman triathlons.

After the birth of his twin sons, Ben reveals that he “pivoted” his business into media, writing, speaking and consulting. He launched one of the world’s first fitness podcasts, the Ben Greenfield Fitness podcast, during that time.

In 2013 and 2014, Ben was named as one of the world’s top 100 most influential people in health and fitness.

In his bio, Ben says that he has helped thousands of people around the world achieve their goals and improve their quality of life – “from high level CEOs to soccer moms to professional athletes and beyond”.

In the media, Ben has contributed to publications such as Forbes, Men’s Health, Huffington Post and Fox News, to name but a few.

Ben became a New York Times bestselling author with his book “Beyond Training”, which was first published in April 2014.

It was during these years that Ben started to make a name for himself as a ‘biohacker’, as he tried a range of self-experimentation techniques to help optimise his health and fitness.

Ben co-founded the supplement company Kion in 2017 along with Angelo Keely. The company makes a range of different food supplements and also sells its own brand of coffee, which is “carefully selected and roasted for flavor and purity”.

Speaking about his journey in an interview with UK newspaper The Times of London in early 2020, Ben said: “We have a gratitude practice as a family every morning, completely overwhelmed and grateful for our opportunities. I work really hard, but I don’t feel like a special guy.”

Later in that same interview, he also revealed how he feels that the health and fitness industry has been changing in recent years.

“There’s this increasing shift and awareness in the fitness community towards this idea that maybe a person’s fitness is kind of meaningless in the long run. Muscles aren’t the key to happiness.”

Ben says that some of his favourite hobbies include reading fiction, playing the guitar and ukulele, spearfishing, bowhunting, plant foraging and cooking.
