Calories in, calories out.

If you're thinner, then you'll run better.

If you're running better, then you're going to hit different metrics because I was a runner in high school and then joined the crew team, same thing.

So if I could go back and talk to my younger self, I would have been like, you need to eat, you need to recover, you need to eat, you need to recover.

Instead of the mantra of calories in, calories out, more cardio, lose weight, lose weight, lose weight.

Because now I educate people as you want to take up space, you want to be strong, you want to look at –

not the idea of losing something, but gaining something, gaining that power, gaining that strength, gaining that bone, gaining that muscle, gaining your period.

Those are the things that I'm trying to educate the younger generation because that was not impressed upon me as a younger athlete, which then had a lot of repercussions later in life.

Luckily, my bone density is fine.

But that's the mentality that we grew up in, right?

When you're looking at the supermodels of the 90s and Kate Moss.

Heroin chic.

Yes, heroin chic, which is the worry now with the GLP-1s coming back and the ballerina body and all the things that we're seeing come back again.

And it is worrisome.

Yeah, the fit and forgets.

In some of the nutrition research, finding that low iron and low vitamin D are huge contributors to it.

So there's that research to investigate too, which is interesting because there are some women also who don't want to go on SSRI or estradiol.

So this is where wearables come into play.

Yeah.

So wearables are not designed to capture women's physiology.
