We surely doesn’t want the same amount all the time… In good cases things get balanced out (it usually happens to me in extreme cases. like, 1000 kcal or 3000+ kcal in the previous day) but it’s not always the case. Once I had a month when I ate 1000 kcal more than before every day without any reason I could see… Normally I am more normal but one even may have weeks and months when they eat less or more… (The mysterious “I can’t really eat in summer” folks… My body wants exactly the same type and amount of food in summer and winter and my family members are the same so it’s especially odd to me…) A drastic woe change may confuse the body, I know that but there are many factors… Stress, sleep, mood…
Many of us have some rare super hungry or super satiated days too… Life is like that I guess.
Until you don’t see anything extreme, let these fluctuations happen
I experienced that a single day can be all over the place, the average of multiple days should be in a smaller range… It’s true for various things, not just the energy intake. Though there are some “rules” for separate days too and they rarely get broken.
I don’t know what was the time for you, I learned I can’t say very much about my day until bedtime (unless I ate a ton way earlier)… There can be huge fluctuations during the day but they may get balanced out later.
But if not, the next day. But that’s rare for me.
