Pros are pros, but you are not one (are you?), you don't have the experience, the time, the regeneration, the genes, the attitude, the money. So you might as well ignore most of what they do, because you are not one of them.

> Sure you won't feel a loss of energy, because you've never had that energy in the first place. I don't understand why you would remove a major fuel source entirely.

That's a bold statement. Have you ever tried it? Did you have energy?

Imagine that you don't bonk, no matter if you eat or not, and you can still keep roughly the same level of intensity for the entirety of your session, however long it might be. As a matter of fact, you feel just as fresh mentally at the end as at the start. That's why.

Which part do you think applies exclusively to the pros though, I think it applies to everybody. I only used the pros as an example, since they are incentivised to perform at their best and therefore are most likely to apply the best fueling strategies.

> Have you ever tried it?

I have not tried it. Can you provide some sources explaining how it gives any more energy than metabolizing fat does?

> Imagine that you don't bonk, no matter if you eat or not, and you can still keep roughly the same level of intensity for the entirety of your session, however long it might be. As a matter of fact, you feel just as fresh mentally at the end as at the start. That's why.

You don't need to be ketogenic for that though, you just gotta keep it slow. One of my very last outdoor rides last year was like that. 100km ride where I kept it strictly in zone 2. It felt easy and I had a blast. Can't say I felt just as fresh as at the start though.

To paraphrase a basketball player:

As a trained amateur, I'm much closer to a pro athlete than an untrained person is to me.

And yes, I don't bonk during long runs/rides/etc. because I do the same thing pros do and eat carbs.
