And we can have the overgrowth of some probiotics that, again, can cause some dysbiosis.

I don't think so. Not from what I've seen.

It is, but you also need some protein that comes from a wide variety of different sources. And the amount of fat that is taken in through a true ketogenic diet is 70 to 80% of your total intake coming from fat. And then that will cause the overgrowth of the bacteria that relies primarily on fatty acids, which down-regulates all the good bacteria that relies on our fibrous fruit and veg.

Because you're not going to be able to consume as much fiber as you need on a ketogenic diet to really invoke this diversity. If we're thinking about invoking diversity, you want 30 different plants across the week. And on a ketogenic diet, you're just not capable of being able to eat as much to create that diversity.

And the reason why it's really important for women to have that diversity is because we have some gut bugs that are responsible for our sex hormone metabolism. So we think about estrogen, progesterone, people think, oh yeah, well, it's released from the ovaries and the adrenals and it goes and hits our target tissues.

But we have this thing called the second pass where our sex hormones will be taken up by the liver bound by sex hormone binding globulin. shot into the intestines through bile, unconjugated or unpacked by these little gut bugs, and then shot back out in the circulation to work.

If we have a lower diversity of the gut microbiome, we don't have those bugs that will help with our sex hormone, I guess, reactivation and the ability for the sex hormones to work optimally.

Yeah.

Yeah.

Absolutely. So if we're looking at cold plunge and it's all the rage, right? So we're seeing, let's get into ice water. It's going to invoke this massive parasympathetic response. I'm going to have lots of cognition and focus. It's going to create a hormonal response that improves my blood glucose. It's going to invoke a lot of autophagy and all the things that we see with fasting as well.

And it gives me this incredible sense of being in control. Male data. We look at women who were in ice bath. It's too cold to invoke those responses. And the reason for that is we have differences in... our skin sensation between men and women with regards to thermoregulation. So women have more subcutaneous fats and more fat under the skin. And we tend to vasoconstrict and vasodilate first.

So that means that blood vessels will constrict tightly and then we'll start to have some internal changes. Or if we're too hot, we'll vasodilate first and then we'll have internal changes to create sweating. So we look at a cold plunge, there's too much constriction and it becomes too much of a threat to women and their bodies don't have the same response to ice water.
