Realistically, for most folks?
10,000 calories seems like it's way too much, and not reasonable for most. For some? Sure.
It's not clear if this is a one time, occasional, or even once a week for a stuffing, or if this is intended be every day. So which is it?
Is this anything like those "cheat day" videos I see on YouTube sometimes? Though most authors/creators who do this, tend to be extremely fit and seem to almost live at the gym. But I've sometimes seen them do 10K or even 15K calories before, but certainly not every day.
If every day back to back, I'm convinced is impossible and would probably make you sick and unwell.
There are those competitive eaters you hear about, but they trained up to it. They also don't eat like that every day and will generally prepare for a couple or few days before the moment of truth.
Personally, I have had 4,000 calorie days several days in a row before, think 5 days. Doing that 2 days in a row is probably not that hard unless you're still quite small and very early on in your gaining journey.
I don't think I could do 10,000 calories in a single day, I don't think. There was one time I did 6,000 calories, but that involved drinking an entire quart of heavy cream, and I didn't feel that great the following day. Granted, that was about 40-45 lbs ago, but still.
True every day life is unlikely to be feasible, since folks have things like jobs to go to.
Maybe it'd be easier to do a 10K calorie day no more than once or twice a month, or at most, once a week.
The OP also mentions something about tracking progress, which suggests this isn't a one off thing.
So to recap, a one-time thing or every day?
When my partner and I first got together, he wanted me to feed him 10k in a day. Mind you, he was 407 at the time and ate 3 - 5k calories a day without stuffing himself.
It took me 3 months of near constant stuffing to get him to that point. And it definitely hurt. Don't get me wrong. He's into that shit. But most aren't.
