How many calories does an average 15-year-old burn in a day?

There are 3,500 calories in 1 pound, does this meani have to burn of 500 calories a day?

• I want to lose a couple pounds before my holiday in a couple weeks. I found out i have to burn off 500 calories a day to lose 1 pound! Is this true? Today i burned off 149 and hoped it would be enough for one day but after reading that i need to do some more. Is burning 500 calories a day healthy? Is it possible and how can i succeed this? I swear it was never that hard to shed a pound?

• Answer:

  for a pound of fat, that would be true. however there is also water weight, and other stuff also. Yes, you could consume 500 calories fewer than you burn on a daily basis, if you eat only healthy (nutrient dense) foods.
