Hi,
You will probably get as many answers as there are ppl on this forum!
Not that that is a bad thing, but it may keep your confusion going...
I suggest you have a look at this nutritional calculator (the whole site is worth a read, if you haven't found it already).

If you are on 1200 cals a day, I'm guessing you want to lose weight?
My attitude is that (broadly speaking) I control my carbs, eat 'normal' protein, and fill up on veg and fats to my appetite. But I'm not trying for structured eating, or a weight loss plan.
Hope that helps!
