I know this is a strange question and i'm not entirely sure how to word it but what are calories?

I mean, what are they in your body, are they energy? What do calories do in your body?

And why is it so important to hit 1200 calories and maintaining a deficit?


Also, the 8 glasses of water a day. Is that just for hydration or is there something else behind that? I usually just drink when i'm thirsty so about 6 glasses a day and that works for me.

Thank you
