They don't get any results and they end up what we call tired but wired. I mean, if you look at most women who make a point to get up, do some training, go exercise, and it happens so often after four weeks of following the same kind of training program as their male partner, their male partner has gotten leaner, fitter, better cognition, focus, all of the things that you want out of fitness.

And the woman's like, how come I'm fatter and tired? And I don't have any like increase in my fitness like my partner does. And I see it all the time. And I'm always explaining, well, one, your partner might get up and go fasted training. Women's bodies don't respond well to fasted training. What's fasted training? I don't even know what the heck this is. Like what is fasted training?

Fasted training means you're not having any food before you go do exercise.

Yep, exactly. And it comes really to the brain, right? So when we start looking at first thing you get up, and our responses are different, where women's brains will start going, okay, where's the food to come in to help bring my stress hormones down and get me started for the day? And men, by the nature of being XY, their brain's like, yeah, okay, I'm going to supply some

And men, by the nature of being XY, their brain's like, yeah, okay, I'm going to supply some

amino acids and some blood sugar and let's get on with the day. Then we'll find some food. That's fine. But women's brain, specifically what we call the hypothalamus, that is really sensitive to blood sugar and food coming in. So if you get up and you start your exercise without any food, the hypothalamus is like, wait a second.

This is a stress to the body that I need to really try to figure out. But if I don't have food to counter the fuel that the muscles are needing from a contraction, I need to find a way to supply that fuel. So it goes into a little bit of a tizzy. And one of the first things that starts to get broken down is your muscle mass, because muscle is a pretty active tissue.

And the hypothalamus is like, well, I don't know if I'm going to be able to supply the food that this muscle needs. if I don't have any food coming in. So it's a very small amount of food that a woman needs first thing in the morning to then go be successful in her training. And it's even if you're going for a walk, a lot of women will get up and go for a walk on the auspice.
