Or dessert.

You eat it because it gives you pleasure.

Not because, you know, you're hungry.

You just ate a full meal.

You still eat dessert because you want to, right?

That's called hedonic hunger.

And that's the sort of emotional hunger.

And that's where...

Really, the problems with ultra processed foods and food addiction lies.

And then there's a third problem, which is called which is a sort of social environmental hunger.

And this is called conditioned hunger.

Right.

And this is drawing on a whole field of behavioral psychology.

So conditioning is where you can sort of pair two things together.

And the classic experiment was Pavlov's dogs.

So if you give dogs food, they'll get hungry, right?

They'll salivate, they'll get hungry.

If you ring a bell and then give them food, they'll soon pair the two together so that when you ring a bell, but don't give them food, they'll still get hungry.

And that's because they've been conditioned, they expect to get food and they're gonna get hungry.

Well, if you think about what happens now, this is exactly what we've done.
