That those studying session can sometimes be too long to be healthy is certainly true, but was not the point argued here.
When someone argues that a Ferrari is a fast car and you criticize that not all red cars are fast, you are arguing against a statement nobody made while still saying something true.
I don't know why you assume that I don't understand that they're saying that their studying is uninterrupted when it's overnight. That doesn't change the fact that sleep deprivation is also something that makes any sort of studying less effective.

In this case, it feels more like someone said that Ferrari is a fast car, and I mentioned that some people can't afford Ferrari's and might find a different car a better fit, and then you came in extremely unhappy with the fact that I dared to mention anything other than a Ferrari because that's the only car OP mentioned. It's extremely common for people to reply to comments making a tangential point, and doing so doesn't at all take away from other people's abilities to have parallel discussions in other subthreads about different points; that's kind of the whole point of this style of forum.
Your point is valid as a tangent, but it doesn’t read as a tangent to me - it reads as attempting to address the point you are responding to.
Just my two cents here.
First world problems; there is so much food that we can make lifestyle choices around it. You can pretend to be a caveman and eat "paleo" since meat is neatly wrapped in plastic at the store and you didn't have to hunt it down. (And if you study the Hadza tribe who are one of the last paleo-bros on the planet you'll find that meat is a small part of their diet). You can forgo certain meats and call your self pescatarian since you can find fish in the middle of a city. And you can intermittently fast since you know that you can quit anytime and stuff yourself full of food.
We as a modern society have to be the most smug of all. Think about every predator in the world. We constantly pay to exercise, to burn off EXTRA calories, where as every other animal on the planet conserves them or expends a vast amount to obtain more.
Tangential, but might be interesting to some:
sometime before the pandemic, after (I think) 30 years of always eating some kind of breakfast, I accidentally missed breakfast once and that day I felt I had significantly less brain fog after lunch.
So I tried again to see if it was just a coincidence, but it had happened again and again.
And, I realized, as long as I don't start to mentally prepare for breakfast I don't start feeling hunger either.
I'm not suggesting this is a good idea for everyone, only that for people like me who has followed "best practice" for decades and doesn't feel too enthusiastic about it, testing out alternative approaches might be a good idea.
PS: the total amount of hunger I feel in a day seems to have gone down too.
My comment is only pointing out that for me it is the opposite: I work better without breakfast.
Do you actually work better, or have you decided that you work better?
As for if I work better or just have decided I work better, I only have 4 or 5 years of experience with this but despite the fact that I love breakfast and lunch I still skip them because the brain fog I seem to get between 1200 and 1400 on days when I eat breakfast just isn't worth it.
Intermittent fasting seems to be a very effective strategy (for reasons unrelated to your point).
Better thing to do is have a routine first. A lot of people don't have any eating habits, it's more of an afterthought or a "whenever I'm hungry I'll eat" kinda thing. You can't base a diet off of that.
If you fix your diet by just eating at the same moments, roughly the same amount of time, only then do you have a baseline. Then make tweaks on that baseline. Evolution instead of revolution, only that will be sustainable.
