I am 13,my metabolism is surely NOT as fast as other people my age...but I'm still NOT overweight...
If I have a glass of fat free milk in the morning and another skim milk glass in th afternoon,will that make me lose weight?How is it possible??

Surprisingly, calcium does have a weight-loss benefit. One study showed that dieters who ate three to four servings of dairy products daily lost 70% more weight in six months than people on the same diet without dairy ??“ and they lost more fat around the middle. Another study found that college-age women who ate a low-calcium diet gained weight, but women who got plenty of calcium maintained a steady weight, or even lost a few pounds.

I am sure you are thinking about all the TV ads that promote drinking milk to loose weight....
Enjoy the milk, but it won't help you loose weight. Exercise and counting calories will!!!

NOPE.
Cut back on carbohydrates and eat healthy but full meals so you don't need to snack in between............
Walk or ride a bike to burn extra calories........
@13, you may still have "baby fat" which will eventually disappear.
