Burning Calories Donating Blood

While donating blood today I noticed a sign that says "You burn about 650 calories by donating blood." How is that?

Do you burn them just through the donation process?
Do you burn them replishing your blood supply?
I asked the nurses at the blood bank and none of them had any idea, the one who put the sign up told me she just read it on the internet.
