HOW a body knows its the next day of new calories eaten

Options
I am almost lost as how to ask this ? properly but I will try my best to put forth what I need an understanding of:

Ok, for EXAMPLE:
Say I reached a total of 1500 calories by 7pm and decided I am not gonna eat ne more cals until the next day.
So, my ? is when is the next day to the BODY? does it automatically know ok around mid-night or 5am is the so called NEXT DAY?
To then start fresh again on calorie intake?
Or what if I ate 1500 for my day then fell asleep for 4 hours as a nap during mid day or sumthing.
Since the body burns calories when you sleep. Would I once again be under 1500 calories?
BASICALLY WHEN AND HOW LONG DOES THE BODY KNOW WHEN ITS THE NEXT DAY TO START OVER FRESH TO TAKE IN THE NEW CALORIES FOR THE DAY STARTING FROM 1 CALORIE TO WHATEVER THE ENDING CALORIE GOAL IS PER DAY?

DOES NE ONE KNO? :)

    The number of calories set is for 24 hours. Your body doesn't 'reset' when you sleep or anything. It's burning all day and all night.

    It doesn't. Your body does not look at calories in/out on a daily basis - its a continuous cycle.
    THiS. For some reason people have this idea that metabolism stops when we go to sleep. There's a reason why you weigh less in the morning (if you sleep at night). Metabolism still runs the same whether you sleep or are awake.

    yeah, it doesn't matter. the body isn't trying to lose weight with you, it's just doing it's job and keeping you alive. if today you eat 500 calories and tomorow you get to 2000, your body will ajust to it. there are no "new calories", it's continuous.

    Just be consistent. I count my "reset" at midnight, so if I have a late-night craving, it comes out of what I can eat the next day.

    I don't think it even matters if you're consistent as long as you track any food eaten on one day or the other. Sometimes my 2am eating (like today) goes on the previous day because I fell asleep without dinner. Sometimes it goes on the next day.

    There goes the theory behind calorie cycling.

    How about not confusing the issue. The OP seems confused enough.

    Its not that the body knows a 24 hour period, it is actually the opposite. As humans we've pretty much organised our world around the orbit of the sun, i.e. a day in time, that happens to be 24hrs so it makes sense for guidelines on calorie consumption to also be based around a 24 hour period. If our day was actually 36 hours long, then we'd likely still have daily targets but those targets would be higher (assuming in said imaginary world our bodies are even the same).

    that is why when I count I count by the week... I have this weird algorhithm that I devised that allows me a certain amount through the week... if I have a daily deficit or overage it goes into the weekly pot of what I can eat :)

    I get bored... and use different systems that all basically boil down to calorie restriction...

    the BASIC point is that you consistently reduce your calories... it doesn't matter WHEN you count food... just that you count it... I work overnights... so my "day" by my sleep cycle would be from 0900-0900... but for calorie counting purposes I use a 0000-2359 day... because it is easier to calculate here on mfp...

    the point is consistency

    Imagine how many meals you would have to eat in a day in order for your metabolism to keep going?? Tupperware would make a fortune!!

    Cool, if you get bored why not try pretending the day is 36 hours long... just for fun ;)

    Calorie cycling???? Thought I'd heard of everything - but this is a new one for me - please explain?

    It's the practice of having higher and lower calorie days. The theory is the high, low, mid days will keep the metabolism "revved" up. Of course it's all bro science. It doesn't matter as long as you keep a weekly deficit.

    I am even starting to think that carb cycling is a bunch of nonsense. When I make cycling I am talking about high, mid, low, high etc. I am starting to think it's much easier just to have set macros for say 6 days and the have one high day. Anyway, I am in another topic now.
