Is milk not good in low amounts? Can't say the same about coke, I guess.

and isn't it tiring calculating the cal in what you should eat or drink?

I'm not calculating, I am guessing and then checking. 👀

And I think it's good to get a feel for what has how many kcal. It already helped me to buy an apple and cherries instead of coke or milk.

I don't intend to do this forever. Will stop when I have healthy eating habits.
