That said, this is something I've changed my tune on a lot.

I come from the classic exercise physiology academic background, and all those people are carbohydrates first, carbohydrates second, third, fourth.

Fat was always shunned.

And I don't think I believe that as much anymore.

Also, we've experienced a lot.

A lot of the people we've worked with, they're fine on moderate to low carbohydrate, even high exercisers, non-athletes, but they train a ton.

You're talking about guys and girls running 60 miles per week, right?

Like real high energy expenditures in terms of performance.

And they're at 100 grams of carbohydrate a day.

They're not eating ketosis at all.

They're not even trying to be, but they just like are fine at 150 grams a day or 200 grams of carbohydrate a day, right?

For 120 to 190 pound like individuals kind of at that, just as some frame of reference for numbers there.

In that case, their fat intakes are way higher and they're fine.

We're not seeing any performance decrements.

They're not having a hard time recovering.

Their sleep isn't going down.

Like sex hormones are fine.

So I actually have just seen enough evidence now anecdotally and empirically being like, I think actually you're fine there.

I think you're okay.

If you're giving yourself, if your endogenous recovery is sufficient, I think you're going to be just fine there.
