To add to what Alan said, I do think as well as the fact that we're more sedentary, as well as we're all living such different lives and we have all of this food noise, our food landscape and the food choices that most people are making now are so, so different to 20, 30, 40, 50 years ago.
And they're almost hijacking our system.
We have evolved to be able to handle excursions in blood sugar, to handle fat, to handle all sorts of things that are thrown against us.
But we haven't evolved to handle the food landscape that's out there that's evolving even more quickly than science can evolve.
There's studies where they actually take people into these kind of chambers and they monitor them for weeks and they actually sleep deprive them.
They say, right, you're going to become a short sleeper, so less than six hours.
And they see anywhere between 150, 300 calories per day increase.
in how many calories they're having just from depriving.
I mean, it's a pretty cool study that these guys do.
And also, so by changing the sleep, it changes the types of foods that you're having.
We did a study at King's called the slumber study, which was one of those sleep extension studies where people who were short sleepers, less than six hours of sleep were asked to increase by two hours, exactly similar to the study you're saying.
And what we saw was that by people increasing their sleep, they had no advice about what food to have at all.
All they were told was the here's good sleep hygiene.
We want you to increase your sleep.
And we happen as part of this to be measuring the kind of food you're having.
Yeah.
they significantly reduced by quite a large amount the amount of sugar intake that they had.
So this deficit in calories is coming from the bad foods as well.
I think there's ways you can fit it into your lifestyle without it feeling daunting as well.
I'm someone that's never liked exercise.
