It doesn't require a lot of digestion because it's pre-digested.

Gastric transit time tends to be very fast.

So how long it stays in the stomach tends to be, it tends to shoot right through the stomach, right?

As opposed to like natural foods, like think about like eating a lot of beans or something like that.

Still carbohydrates, but it's like, there's a lot of chewing.

There's a lot of...

you know, digestion.

It's not a fast process.

So that makes a difference to the ultimate hormonal response, which is then going to partition the energy into this sort of, do you store it or do you burn it sort of thing.

so this this food matrix is very important that's why ultra processed foods are dangerous it's actually only one of the reasons they're dangerous they're actually dangerous for multiple reasons but from a hedonic side that is from a pleasure side the foods are engineered of course to give maximum pleasure right and people have well documented this you talk about bliss points and salt and sugar and fat but you also have artificial

sweeteners, artificial flavors, you've got artificial colors, you've got flavor enhancers like MSG and maltodextrin.

You make sure the mouthfeel is good by putting in texturizers and emulsifiers, right?

So you can do anything with these things.

There's no limit on how much sugar you put in.

Things can be 100% sugar, right?

There's nothing sort of natural in the natural world except maybe honey that is 100% sugar like that, right?

So the whole point is that it's going to give you maximum pleasure, very quick hits because you're getting this huge dopamine spikes and all this sort of thing.

At the same time, they ratchet down your satiety.

So anything that turns on satiety signaling, they get rid of it.

Why?
