Maybe this has been asked before, if so please point me to it and lock the thread.

How important is it to know the exact number of calories consumed in a day and to know exactly where they are coming from?
I ask only because I am pretty sure the majority of the population does not have a clue how much they eat and what macros and the like they are consuming but not everyone is dangerously fat.
I also ask because I do not actively count now and have kind of hit a stumbling block. I know my breakfast is usually around 350 cal and my lunch is around 550 cal. I snack for around 800 cal all day which leaves me around 1000 for dinner- and still have a 500-1000 deficit with my exercise, this should be enough to continue losing.
I read posts on this board from people who are looking at exact numbers of calories and exact numbers of macros and having meals planned for days/weeks... Is all this necessary?
If one eats well balanced meals- nothing too crazy- and knows around what the calories are is it really necessary to know the exact number?

Honestly just wondering.
