"I'd probably hope that I'm a son for my mum and dad that you can be proud of."
That's the answer Joe Cross gave me when I asked him about his biggest achievement.
It's December 2014. Joe is touring the UK with Fat, Sick and Nearly Dead 2, the follow-up to the documentary that had shops selling out of juicers after Channel 5 showed it in 2013. A few days earlier I've watched the new film in Liverpool. Now he's given up some of his day off to sit down with me for an interview.
At the time I'm running Natural Juice Junkie, sharing everything I'd learned about juicing and getting my own health back.
His biggest achievement
I ask him what he thinks his biggest achievement in life is so far.
You might expect him to talk about the films. Millions of people around the world have watched them, and he's changed a lot of lives.
He doesn't mention them. He says he doesn't really think about it like that. Then he says the line about his mum and dad.
And he adds this: "I'm happy that I'm happy... I'm happy where I am and I don't look back and have regrets." If you can just be happy with where you are, he says, that's an achievement in itself.
I tell him on the spot that I love his first thought being his mum and dad, because I think that's something everybody wants, whatever they do.
Routine is the hard part
The film I've just watched makes the point that juicing vegetables has huge benefits, but staying healthy takes more than that. So I ask him what the hardest thing has been about looking after his own health since the first film.
His answer was one word, really. Routine.
He's living on the road. No gym round the corner, no mates to train with, no kitchen to get the juicer out in, no local farm. "The routine is the hard part," he tells me.
And then the twist. When you've got a routine, you want what he's got. Different cities, different hotels, seeing the world. When you're on the road, you want the routine. "That's us humans. We're never happy."
He admits he'd slipped a few years earlier. Working too hard, travelling too much, not finding time to move. Before this tour he spent a month training two hours a day, because he knew what the tour would do to him.
A great life, with a catch
I also ask him if there's a downside to being Joe from Fat, Sick and Nearly Dead, rather than just Joe.
He's honest. Yes, there is. If he ends up next to someone on a flight who wants to talk about juice for half an hour, and ask the questions he's been asked a million times, he tries to do it with a smile. Some days he doesn't have the energy. But the upside outweighs it, he says, "hundreds to one". And then: "I have a great life."
An ice cream in Harrods
My favourite bit comes when I ask about his guilty pleasure.
Chocolate ice cream. Choc chip, if we're being specific.
He tells me he's been too extreme about treats in the past. He'd label something as bad, then feel bad when he had it, and then have more. So he's changed how he thinks about it. The other day, he walked 45 minutes to Harrods for an ice cream, and 45 minutes back. Basically an eight-mile walk for one good ice cream.
"I enjoyed the walk and enjoyed the ice cream," he says. No guilt. No drama.
Think about it. Here was a man the world knew for what he'd changed in his body. And the things he talked about were his mum and dad, being content with where he was, and the daily routine nobody sees.
It's easy to chase the next big thing. The big public stuff is what other people see. The routine, the people who are proud of you, being okay with where you are today, those are the bits you actually live in.
What would your answer be? If someone sat you down tomorrow and asked about your biggest achievement so far, what would you say first?
