If it's a crazy schedule then okay but the only thing about Goggins's diet when he was losing weight was that he ate 800 kcal a day.
My point is that it's not impressive or isn't hard by any means. Some people eat that much by accident just because they don't feel like eating. Even skipping a full day of eating is not a big deal.
What was impressive and hard wasn't his diet back then but the fact that he kept his diet AND his workout protocol
for over two months. The entire difficulty is in the routine, not in one day. But that wasn't covered, probably because that would be way too demanding for a clickbaity YouTube video.
But still, one day is nothing. You can't tell how hard it is by stepping into someone's shoes for one day. Most people would be able to do 2-3 workouts a day. But do that for a few weeks and that's when you can really tell how hard it is.
It would be akin to creating a video "For one day I read like Bill Gates." Bill Gates reads about 3 hours a day. It's not impressive at all to read for 3 hours (similar to 800 kcal a day). What's impressive is doing it every day.
That's what I meant by my comment about people being event-oriented. They're picking a tiny little thing off someone's routine which doesn't reflect them at all. It would be like me riding a bike for the same amount of hours as you regularly do and then claiming I learned something during that day.
One guy who does this "stepping into someone's shoes" thing is this guy:

That's something impressive because it's not something any regular guy off the street can do. It's extreme and it's long. In this case, yeah, you can learn how incredibly tough these guys are.
