Donating blood does not "burn" calories.

Huh that's really quite interesting and it seems to make sense.

Also, I never exercise when I donate and usually plan my donations around my break days. Sometimes I just get woozy sitting in the chair so for now I'll just settle in with a bowl of grapes and recover :)

People have taken the statement that it takes about 650 calories for the body to replace a pint of whole blood and turned it into stating that you "burn" those calories due to donation. They are two totally different things. A pint of whole blood weighs about a pound but once you have had the fluids you are requested to drink after donation, you should see no weight change due to donation.

I've read this before, but honestly I can't confirm whether or not it is true.

I know that whenever I have donated blood, the Red Cross suggested that I double up on fluids for a couple of days. I believe it takes at least 30 days for your body to replenish that pint.

I don't know how many calories you eat, but I would suggest eating a few more calories to ensure that your blood sugar levels are stable. BTW, no exercise at all. I made the mistake of thinking I could get a short workout on an elliptical in after donating. I nearly passed out after 10 minutes.

I googled it and came up with
After donating blood, the body replaces all of the blood volume within 48 hours, and all the red blood cells within four to eight weeks. The University of California in San Diego estimate that for every one pint of blood donated, 650 calories are burned as the body must replenish itself

don't know if it is true

I donated blood today, and aside from helping three random people in need, I hear that this also burns around 600 calories. Can anyone confirm this? Regardless of the answer I'll continue donating, but I'm just curious.
