I was taken by a senior colleague to some fancy chmancy dinner. It's like Harry Potter style.

The guy opposite me, bearded white dude, says, so what do you do? What do you do?

And you're supposed to answer, right? So what do you do what do you do and you're supposed answer right so

what do you do and so I was a young chap at the time and so I told him I said I

studied the genetics of severe obesity and I remember what he did to my dying

day he went do you know what your problem is?

Dude I'm trying to have dinner. I don't know what's your problem and then he went you give

Fat people exactly like that an excuse. That's Giles Yo.

Today he's a world-renowned geneticist at the University of Cambridge.

He's a pioneer in the field of obesity research.

But that dinner party he's describing was 20 years ago at a time when

researchers had very different views on what causes obesity.

At the time I was just saying,

look, do you say that we're giving people an excuse

if they have muscular dystrophy?

Would I suddenly be giving them an excuse? And he went, yeah, but you have no choice

when you get cancer or you have no choice when you have a choice when you're a

muscular dystrophy, you have a choice about what you eat.

I don't think I convinced him, and so till that day I didn't have to try and convince other people,

I guess.

Professor Yoes says this conversation was the catalyst that kick-started his career.

And it was from there, I then did it as more than a job.
