How can I count calories?

[drmamakhulusum]

I receive meals at school and my mum usually cooks at home. How should I keep track of what I’m eating?

The only way to know how many calories you're eating is to cook your own food.

You shouldn't count calories because you're still going through puberty. But why not offer to cook a few nights a week?
