Oh, okay. I probably don't have as good an answer. Genetics does not have as good an answer about why different people eat differently, aside from cultural differences at the moment. So the genetics. The reason behind that is because it's very difficult to accurately determine what someone has eaten in order to do genetics.

What we do know, because we can actually observe, is how people of different ethnicities are susceptible to different diseases. So famously, East Asian people, people that look like me, South Asian people, Indian, Pakistanis, Bangladeshis, cannot get as large BMI-wise, before becoming at risk of type 2 diabetes, right?

Compared to white people, Polynesians famously, who can get pretty large before they actually end up getting diseases. So that's a classic example where this is why South Asian people, East Asian people have a higher predisposition of diabetes, even though... obesity is not particularly a big thing in their cultures. But then you then begin to look at body shape. That does matter as well.

Where do you put your fat? Do you tend to put the fat on your bum, on your tummy? How tall are you? How short are you? And all of these things, which we can see visually, we can see, there are people who are then susceptible or not susceptible to specific diseases. Other things you can't see.

Why are African-Americans, for example, more likely to end up with cardiovascular heart disease, less likely with diabetes, whereas why are Indians more? And so you then begin to ask the question, and there we have genetics.

There are more than a thousand genes for body weight. The obese gene in chapter two, which I talk about, is this leptin gene, is this gene which lets your brain know how much fat you have. Ah. So that's the exact gene. Leptin is the gene that I'm talking about in chapter two with the obese. It's called the obese gene because the mouse was called obese.

There was a lack of imagination because the mouse was a naturally occurring mouse that had a mutation in the same gene. Scientists found out what that was and then found out that it was conserved in humans. And that's where my boss, Steve O'Reilly, then came in and found that that gene was also mutated in some humans. So that's the obese gene.

It's the fat gene, fat gene, meaning gene from fat, that lets your brain know how much fat you have.

So leptin, for whatever odd reason, is pretty much binary. So if you have a little bit of it, you're fine. If you have none of it, you're not. However, there is obviously a pathway. Leptin signals to the brain, which signals to something else. And there is another gene that I looked at called MC4R. It's part of the pathway. It's is a rheostat. It's like a thermostat.

And so, for example, we have found thousands of different mutations in this gene. And you can imagine that depending on the severity of the dysfunction, some are completely dead, some are 70% functional, we can predict how much someone will eat in a test buffet meal scenario if they have a 50% functioning gene versus a zero functioning gene. And we now know that 0.3% in this country at least.
