who counts Calories ? , to me thats like buying Drinking Mineral Water , why ? , don't you have Water at home ?

The reason I drink mineral water is for the minerals and how they make my stomach feel, not because it has zero calories. If I eat something spicy I might drink mineral water to calm down my stomach.

calories are not a true reflection of how much energy you burn or store. Metabolism can be increased if you eat more fats of certain types & proteins. Some carbs are high in fiber and those fibers have calories yet they can be resistant fibers that don’t make you gain weight, or the type of fiber that doesn’t break down and is eliminated as roughage. If you heat wheat bread and eat it warm it’ll give more energy because you’ve broken down the resistant starch and it gets digested and absorbed.. If you freeze a loaf of bread for a month & thaw it out you get more resistant starch and much less digested as a result.

I track my food so i have an idea how much protein, fibre, carbs etc. I'm getting, and an idea how many calories per day

I have done this it can be a fun way to lose weight, if you like number games.

it's important in order to lose weight, at least in the start. I need to stay roughly around 1800 calories to not gain weight

It was the only way I was able to lose weight.
To completely ignore calories to me is like flying blind.
