Calorie Deficit Days

I have been doing OMAD for 3 years, but I also do 3 calorie deficit days a week. One moderate deficit, one medium, and one large. My usual day calorie-wise is 2100 calories. The way I do the one large calorie deficit day is that I wait until very late in my eating window to have that one meal, and that one meal is unusually high in protein and fat and therefore very satiating. That one meal can be 1000 calories, but because it is late in the day and very satiating, that’s it for food for that day, which translates into a 1100 calorie deficit. I was wondering if anyone else does calorie deficit days, and, if so, how they go about it — what their strategy is?
