Hello, you lovely lot. Hope you're doing all right in body and mind. Because the two are

always dancing together, aren't they? Which isn't much of a secret. Not really. We know that even

a placebo can make us feel good. Now, long-time listeners might remember me banging on about

Alyacrum's milkshake experiment. It's one of my

favourites because it shows just how much our mindset can trick our body. So, spoiler alert,

these were two identical milkshakes, but they had completely different effects, let me tell you.

So here's the setup. Volunteers were roped in to drink milkshakes twice.

And they were paid for it as well, which honestly sounds like my kind of science experiment.

But there was a catch.

Both times they'd be hooked up to an IV while their blood was tested.

And they had to come first thing in the morning having skipped

breakfast. They wanted them to be a little bit hungry. The participants were all told

that they were going to be monitored to see what effects certain nutrients had on their body.

But that wasn't true. If ever you get signed up for any sort of psychology experiment,

whatever they tell you isn't true, any experiment really. Because the researchers were actually

looking at a hormone called grailin. Think of grailin as your bodies get up and find food alarm.

It makes you feel hungry and it slows your metabolism down a little just in case

you don't find anything to eat when you go out hunting. We've got to remember we're not built for

Although I'm yet to see a gazelle in the supermarket, not even in the

Middle Island Aldi, because we've moved on a little bit. Anyway, once we eat and feel satisfied,

grailing levels usually drop and our body speeds up the metabolism again. So, could simply
