Exactly.

It can also tap more into our liver and muscle glycogen stores. Okay, so it's going to say, okay, well, we have a little bit of blood glucose. We need a little bit more. So let's tap into the stores and pull them out.

Exactly. It has an alternative fuel source.

When we look tribally, I might get hit by some sociologists who are like, wait, this isn't completely true. But for the exception, there are some tribes that didn't fit into this. But for the general idea from a biological evolutionary standpoint.

when we had times of low calorie intake so we had to go find the beast or we had to go out and find calories it was at a disadvantage for the woman to be pregnant or to have a baby an extra mouth to feed so in times of low food intake the reproductive system or the endocrine system of a woman would wind down so she would become amenorrheic or lose her menstrual cycle for a while

But it didn't affect men in that same way because they had to lean up and get fitter and faster because they had to go fight the beast where they had to go find the calories and bring it back. So when we're looking from that evolutionary standpoint, in times of low calorie intake or low food intake, a woman's body will start to conserve and wind down because it thinks there's a famine coming.

But for men, they're not as sensitive and the body's like, oh, not a lot of calories coming in. That must mean there's a fight that I have to prepare for. So I'm going to lean up. I'm going to address all of my fuel systems so that I can tap into all these alternative fuel systems so that I will have the energy to be able to go and fight the beast to bring the calories back.

So when there's adequate calories available, we see that women will lean up. they'll become more acutely aware, cognitive function comes up, carbohydrates are really important. So we see that there is a development of egg maturation.

We have better endocrine pulse, so that means that our hormones that pulse on a daily basis, they actually have the full pulse and return to baseline to encourage the body to have a really robust endocrine system. So that's thyroid, that's our menstrual cycle, it's all of the things. But when we start pulling the calories back, all that stuff winds down.
