What Zach Bitter eats when running 100 miles | Lex Fridman Podcast Clips 

Well played Sir.

I know this is a joke but if you gradually built up to it you probably could

Pasta & Pizza is my Favorite...👍👍👍

Hahah I love it 😂😎

Female vs male biology lol if it works for her it might work for you though right

And blow up due to GI issues like Courtney did in two of the most prestigious ultras in the US :-)

for real lol. for me doing 6 miles in an hour is very hard. I think I could do it but it would be rough

Not really. There's two different approaches here. He says even as a fat adapted athlete, he's still getting 10-20% of his energy from carbs so he needs to keep his muscle glycogen topped up. So he has some the day before and consumes a little during. A non-fat adapted athlete might be getting 50-60% of their energy from carbs, which would require more loading. The fat Vs carb debate for ultra endurance athletes is complicated because A) You're always going to use both B) You burn SO MANY calories

It can be beneficial for shorter and higher intensity types of exercise or sport.

Tbh just eating a balanced and healthy diet is all you need

@@MrStruggle0 agreed

@@MrStruggle0 difficult to do Or everybody would do it otherwise.

😄

I see what you did there 😃

Is gewoon nederlands

You can train it like everything else

I was thinking the same as you, this could be psychosomatic pseudo-science. At the very least, more research is needed, it's probably not as definitive as this gentleman makes it.

He may not go into his normal diet in this clip but this guy follows a pretty strict keto diet year round. He's certainly not going carb free the morning of a 100 mile race to try and jump into ketosis. In fact he probably eats far, far more carbs during these 100 mile races than he normally would cumulatively over the course of multiple days. That is what he is explaining in terms of replenishing his glucose every hour or so as it depletes to maximize performance. At the pace he's running and for that long, even being fat adapted it's beneficial for performance to get some carbohydrates. Lex brought up fiber and stomach issues but I would guess this guy is eating some form of liquid carbohydrates. A tablespoon of honey has about 15 g of sugar, zero fiber, and can easily be consumed.

@@rmccluskey91 You sound super knowledgeable about this topic, I'm going to speculate that you are in excellent physical condition ... Naive question, do some people cut out ALL carbs permanently...Is this realistic... Is it recommended in some cases...

Metabolising fats and entering ketosis are different things though. You only ger into ketosis when you cannot longer metaolize fats directly.

Hard to tell with lex sometimes lol

I'm sure he's more interested than it seems. I know he runs quite a bit so having someone so well known in the running world has to be cool for him to learn from.

Sounds like you forgot he’s a world record holder!

He ran 100 miles at a 7 minute per mile pace, whatever he’s doing is working.
