And what they found was that those who were able to extend their sleep actually made healthier choices, such that they reduced, without being told to, their intake of free sugar by about 10 grams.

Without being given any advice.

Yeah, without being told to.

Yeah, without being told to.

But I think all 20, 30-year-olds think that.

Yeah, I think it's that we have to think of these four pillars together of health. We can't look at diet on its own, can't look at sleep on its own, can't look at stress on its own, we can't look at physical activity on its own. So if we want to improve our health through diet, I think We must be looking at our sleep habits, which we can to a certain extent control. Not always.

I know some people have to work shifts. Some people don't have a choice. They're woken up by their kids, etc. We need to look at our stress. I know that's one of the hardest things to change. We need to look at our physical activity and our diet. And they are all so interconnected.

So this is some research that we published where we looked at people when they'd had a good night's sleep and we looked at people when they'd had a bad night's sleep. And we looked at their post-meal, post-prandial glucose response. So that basically means after having your breakfast, that's got some carbohydrate in it, how much does your blood glucose increase?

We call this the postprandial glucose response because postprandial is Greek for post-meal, and so it's a term we use a lot in the science.

And we looked at individuals' post-meal glucose response when they'd had a good night's sleep and when they'd had a bad night's sleep, and what we found was within the same individual, if they'd had a bad night's sleep, their post-meal glucose response, so after breakfast, was a lot higher... than if they'd had a good night's sleep.

So what this shows, I think, quite nicely, if we think back to what you said about how you wake up more hungry when you've not had enough sleep, we know that people make poorer dietary choices, for example, from the slumber study, And then we know that the metabolic responses to those are worse.
