And I put you on a bike and you're in my research facility.

Like those are the numbers that work.

When you cross over into humans, you start getting really tired of goo.

don't want to taste sugary drinks anymore.

And so when you get past a couple of hours of exercise, then you actually start really paying attention to texture and flavor profile and mouthfeel because that stuff starts to matter and you can't hit those numbers.

They're just not realistic.

So if you're going to try to do something like this, pick your poison in terms of the carbohydrate source.

This is the fast sugars.

But if you're going to go for more in a couple of hours, you got to really think carefully about, are you sure you're going to like that taste of that for six hours?

Because you probably won't.

Depends on...

It depends on what you had starting with.

So did you feed before or did you not?

That is automatically our context.

If you fed before, then we don't have to worry about as much directly after.

If you're fasted, we've got to worry about more.

The other context we have to pay attention to, again, what's our total caloric intake, what's our carbohydrate intake throughout the day, and when are we going to train again?

Some of our folks, again, training multiple times per day, we are going to go absolutely out of our way to get 100 grams of carbohydrate post-exercise if it's a hard training session.

rough number.

Again, that number scales up and down with physical size and caloric expenditure, things like that.
