That's messed up.

Like estrogen helped your body use glucose for energy and now she's gone and your cells or she's going away, your cells don't know how to keep itself metabolically healthy.

So this is why so many women gain weight.

Your go-to at that point is fasting.

Like with Age Like a Girl, I have doubled down on fasting for menopausal women.

It is absolutely the tool.

And let me tell you why.

When you go, and we can break it out according to somebody's lifestyle, but when you go into a longer fasted state, what happens is your body makes a ketone.

And the only way it can make a ketone is by burning fat.

So it has to burn fat in order to make the ketone.

The ketone goes up into your brain.

It turns off hunger, but it also sharpens your mental clarity.

And it also, by the way, increases a neurotransmitter called GABA that calms you.

So I can be 48 years old, have major brain fog, have been gaining weight just looking at food, and now all of a sudden I'm teaching that 48-year-old to go into a 15, 17-hour fast, and they're going to lose weight and increase their mental clarity because they've put this tool into place that's going to give them both weight loss and mental clarity.

I'll give you another interesting conversation I had, and I talk about it in the book.

Lisa Moscone, she's like the number one female brain researcher right now.

I brought her on my podcast and said, tell me what menopausal women should be eating when they go into menopause because the brain isn't as good as using glucose.

And she was like, well, they need to learn how to make ketones.

I'm like, yes, exactly.

So we're not bringing the ketone into the brain picture for menopausal women.
