And they also found that obesity causes change in the gut flora, not the other way around.

They use Mendelian randomization to show that higher BMI actively causes changes in the gut microbiome, which this really should just settle the direction of that relationship.

Cause a lot of I know a lot of alternative health influencers argue that obesity is caused by gut microbiome being a certain way.

And

in fact it's the other way around.

So this probably also explains why a lot of research that attempts to alter the gut microbiome in order to treat obesity has not resulted in improvements in

in BMI or other disease states because the underlying problem is genetic.

Yeah.

Oh, a apparently not.

Apparently I learned something new today.

Okay, so the Instagrammers are practicing evidence based medicine now?

So it was something about the Doppler, specifically the Doppler test, not just any ultrasound that was

So I guess they're trying to take down big ultrasound?

Big ultrasound.

There's yes.

So in other words, they they could have just happened to have a couple of really small babies for some other reason that happened to be in the intervention group, like two two or three different

Patience.

And if they had been allocated differently, the e effect could have even gone the other way, maybe made it look like intense Dopplering prevents growth restriction.

Yeah, and it I know it's just speculation to think about pathophysiology, but there doesn't really seem to be any biologic plausibility that would lead to that kind of outcome where there's only a few outliers and not like that the average birth weight of the whole group would be lower with i if you're gonna claim that it causes growth restriction, but then the average weight isn't lower.
