I had looked at mild levels of dehydration. So this is like what many people walk around with

on a given day. And what we saw was that metabolism is flexible. That means that we shift to more

a preference to carbohydrates instead of fat during mild levels of dehydration. The majority of

athletes are showing up dehydrated. And majority of exercisers are showing up dehydrated. And majority of exercises

are showing up dehydrated. And yet we have all this education out there. 40 to 60% of people

are still showing up to exercise in a hypohydrated state. What we noticed was that in females,

when they came hydrated to exercise, within even 20 minutes, they'd be losing 0.5% of their body mess. And yet,

they were shifting metabolism to using more carbohydrates. And so if you're blowing through your

carbohydrates more at that final push at the end of exercise, so you can't get that next

gear to really get the high intensity. This causes, you know, perceived effort to go up.

It causes you fatigue sooner. The main takeaway from me, no longer could you drink to thirst.

You actually had to have a performance strategy in place for hydration.

So wonderful to have you here.

This has been a long time coming.

I've been wanting to get you in this chair and talk to you for so long.

You have had just an epic career that I'm continuously trying to wrap my brain around.

Like you're a dual sport national team athlete, like national team athlete, which is wild to me.

You played in completely different disciplines.

You were cycling, road cycling, and ice hockey, and you played for the Canadian national team.

That's just wild.

And you also are a renowned exercise physiologist. So you kind of come at this from,
