Max Guerois will turn 30 in a couple years but, internally, he’s a fresh-faced 18-year-old.
Guerois is 28 but claims he has the ‘biological age’ of someone a decade younger after imitating controversial biohacker Bryan Johnson.
He has spent the past two years following Johnson’s ‘Blueprint’ plan for longevity, which involves a rigorous sleep, diet and exercise routine.
Guerois walks 11,000 steps a day. Eight hours of sleep minimum is non-negotiable. He also works out five times a week, two sessions focused on weight lifting and two focused on cardio.
The results have been miraculous. He has never looked or felt better and friends are regularly asking him for his work out secrets.
Mr Guerois said: ‘A lot can happen in a year. Each day, I’m feeling more energized. My body has definitely changed. My overall health is at its peak.
‘I’ve learned a lot from the Blueprint and other protocols.’

Guerois — who is from France — started on the longevity plan after being inspired by Bryan Johnson, 47, who is spending $2million a year in an attempt to de-age his body and avoid death.
The Blueprint protocol is designed to slow biological aging and optimize health.
Its number one priority is for someone to achieve consistent, high quality sleep of at least seven hours every night.
Johnson describes sleep as the most important thing someone can do for longevity, and describes himself as a ‘self-confessed sleep fanatic’.
In the US, surveys suggest about one in three adults fail to get a good night’s sleep.
The blueprint then urges users to focus on eating a fresh diet primarily composed of vegetables, nuts and proteins. Johnson eats about 2,250 calories every day, while Guerois doesn’t reveal an exact calorie count.
It also tells people to exercise about six hours every week, with three sessions focusing on weight lifting and three sessions focusing on cardio.
Guerois does not follow the plan exactly, having tailored it down to meet his own needs and working schedule, but has been thrilled with the results.
He sleeps about eight hours every night, tracked by his Garmin, going to bed around 11pm and waking up around 8am.
For exercise, he walks 11,000 steps a day and works out four times a week — with two strength training workouts, a HIIT workout and one half marathon distance run.
He follows a Blueprint-inspired diet for five days every week, but allows some laxity on the other two days.

He has also taken ice baths as part of his longevity journey, although these have not been worked completely into his routine
His mornings begin with supplements and raw milk with cocoa and a cup of coffee.
Johnson urges people to consume coca powder because of its antioxidants, which can help reduce aging, while milk is popular among many longevity enthusiasts because it is nutrient-dense and contains plenty of proteins and healthy fats.
For lunch, he has a super veggie bowl containing black lentils, cauliflower, chickpeas, eggplant and tomatoes with chicken or eggs, with a dessert of nutty pudding.
This is part of maintaining the vegetable-heavy side of Blueprint, which Johnson says is important for boosting gut health and reducing inflammation levels in the body. It also helps to minimize any sudden spikes in blood sugar.
And dinner is a mixture of vegetables, nuts, seeds and berries alongside sweet potatoes with avocado or fennel salad. He tries to eat it early in the afternoon.
This is similar to Johnson’s dinner, and also helps to boost gut health and reduce inflammation levels — which can lead to more rapid aging.
He has steered clear of some of Mr Johnson’s more extreme interventions, such as tracking his erections at night or going to bed at 8.30pm.
Guerois said it had been challenging to follow the plan, and that he had found the best way to keep to it was to allow some time off.
‘I apply the 80/20 principle,’ he said, ‘perfect compliance isn’t sustainable’.
Guerois, who is also a co-founder of longevity company ZERO, continued: ‘My advice would be to start small — focus on sleep quality first, then gradually add protocols as they become habits.’
He added: ‘Everything is about nutrition, sleep and exercise (fix these fundamentals before buying supplements).
‘You can only improve what you measure. And surround yourself with friends for accountability.’
