So I just went and donated blood again and durring the recovery period it occured to me that it takes quite a bit of work for your body to regenerate that lost blood volume and the actual blood cells. Regrowing that many cells seems like it would be fairly energetically intensive. So how many calories does producing all those new blood cells actually consume? Is there even a way to know that?
So I can shotgun two pints of beer after a donation (gotta rehydrate!) and still be a couple hundred calories ahead? Win-win!
And you’ll get drunker due to the blood loss!
brb, donating blood
Jokes aside, you shouldn’t drink alcohol the day before and after your donation
