What are your personal preferences?

Are you training in the morning?

Are you training in the evening?

All these other factors that are now, again, contextualized are my true answer.

And I hate to be wishwashy on that, but that's the most honest answer because I deal with a lot of people with different goals and different scenarios.

So the science can lead us in one direction, but the actual layering on top of what would I really recommend a human do, that in this scenario matters more.

So if you look at the research very specifically on fasting exercise,

Always depends on the type of exercise.

You mentioned you were really careful about saying like, I'm under 60 minutes, right?

I'm under 60 minutes.

Like I know you're aware that that answer will change, right?

What am I optimizing for?

Am I optimizing for performance?

Am I optimizing for feeling better that day?

More focused that day?

Am I optimizing for the happiness, the personal?

There's so many different reasons why one would exercise that you have to answer all those questions and figure out, well, what lever am I trying to pull here?

What am I trying to get out of it?

So do we have people, I'll answer this way.

Do we ever take somebody and say, hey, you need to start doing your endurance work in the morning fasted?
