Average Weight Per Country How Many Calories Do I Need A Day Based On My Lifestyle?

How many calories do I need a day based on my lifestyle? - average weight per country

I am 15 years and an average weight and size, I think. I'm 5 "6 1 / 2 inches and weighs about 135 pounds. Corro-country skiing (about 5 miles a day). I'm very busy. I want my weight to 120 pounds. I do not ask him for a crash diet, because I've been there B4 (for anorexia). I wonder how many calories you need daily to lose weight and keep my energy. Can anyone give me a fork?
