And it's just sensing. So you have blood that circulates through the brain. It senses temperature, how hot your blood is.

Yeah. So it's, yeah, it is a thermostat. It's the appetite control center. It's how your body responds to salt, how your body responds to protein, carbohydrate. Do I need more? Do I need less? So it's like the control center for the most part. So for women who come in and they're doing fasted training, the hypothalamus is like, wait a second, we don't have any blood sugar.

So it's like the control center for the most part. So for women who come in and they're doing fasted training, the hypothalamus is like, wait a second, we don't have any blood sugar.

We don't have enough carbohydrate to actually do this kind of training. So what I'm going to do is I'm going to create a little bit of a dysfunction here, and I'm going to start downturning all the other systems that need the same kind of fuel. because I don't have enough just to do these muscle contractions.

Absolutely. So if a woman comes to me and is like, I want to lose weight, and I've been doing fasted training, I get up, I have a black coffee, I go to the gym, I do my lifting, I do some of my cardio.

And then I'm not that hungry because I did a hard workout at the gym. I might have a protein recovery shake. And then I'll hold off eating my first meal until noon. I always turn to them and go, well, why did you go to the gym? Because all you've effectively done is burn through your lean mass. So your body needs to have some fuel.

I always turn to them and go, well, why did you go to the gym? Because all you've effectively done is burn through your lean mass. So your body needs to have some fuel.

And the first thing that goes is lean mass because it's a very active energy. component of the body. So it would be better for you as a woman to have maybe 15 grams of protein.

If you're going to do strength or 15 grams of protein with 30 grams of carb, which isn't a lot before you go do cardio and strength, because this is just enough to raise your blood sugar to circulate to the hypothalamus that yes, there's some nutrition coming in. I'm able to get that blood sugar working. I'm able to get that blood sugar into the muscle.

I'm able to get that blood sugar working. I'm able to get that blood sugar into the muscle.

I'm able to stimulate the mitochondria in the muscle to actually use some more free fatty acids. I'm able to tell the liver that I can actually get through this and use these free fatty acids instead of storing them. It only takes a little bit of food to then have benefit for what you're doing. For a man, if he's like comes in, I have a black coffee. I go to the gym. I do my strength.

I might do a little cardio, have my protein afterwards. And then I might delay my meal. That's all right. Because you have a longer window for recovery. The hypothalamus isn't as sensitive. You're not burning through a lean mass. You're developing a stress on the body.

And we know that it's really good that you had that protein post-exercise because that's going to create some muscle protein synthesis and hold you over till you have your meal.
