will donating blood help me loose weight?

anyone know?

Yes until you get to the juice and cookie table.

Working out will help you un-loose the weight.

Your body replenishes the fluid loss quickly. So blood or plasma donation will not work as a weight loss tactic.

And no, donating a kidney to lose weight isn’t a terrific strategy either.

Even if donating a pint of blood did work to help you lose a little weight, you’re not allowed to donate often enough for it to make a real difference. In the U.S., you’re only allowed to donate blood once every 56 days.

Not that I am aware of, and I have a hard time imaging a mechanism that would explain how it could.

Are you concerned that a side effect of giving blood is losing weight which would be a bad thing? Or are you trying to come up with quick ways to lose a pound or two that doesn’t involve diet or exercise?

It would reduce your weight by a little if you went to a weigh-in immediately afterwards and for some reason wanted to be a pound or so lighter. For actual sustained weight loss, no, it wouldn’t help at all.

Cecil speaks: Can I donate blood to lose weight? - The Straight Dope

Blood does contain calories, but not all that many. By donating as often as possible you will lose 3600 calories per year in blood, about the same as the number of calories in a pound of fat tissue.

Immediate results: a pint of blood weighs less than a pound.

Even giving birth doesn’t guarantee a wonderful weight loss. Ask any new mommy who has popped out a gigantic eight pounder, and then cried over her scale that shows only a five pound loss.

Oh, the inhumanity!

Tried it. You more than make up the difference with donuts, cookies and juice before you even leave donation place.

You just can’t give enough blood to make that much of a difference (a few hundred calories per time, every, what, 8 weeks?), and since you’re also required to abstain from exercise that day, it’s a bit of a wash.

It’s still a good thing to do, of course.

If you want to motivate yourself to lose weight by helping others, why not volunteer? I’m pretty sure I burn a ton more calories when I’m with the kid I mentor than when giving blood – plus, it’s fun! There are a zillion activities that will get you off your butt while helping out your fellow humans.

And you should - indeed, the volunteers will often insist, especially if you look woozy.

Whatever the caloric content of blood, it doesn’t make sense that it would take that many calories of consumption to replace it. Replacing blood is a metabolic process and presumably some calories are burned converting food into blood.

I still doubt it’s significant.

Yes so in summary, donating blood is not an effective solution for weight loose.

This gave me the laughs. :):):):slight_smile:

Guess donating blood would be part of the list on how to lose weight without exercise. Great stuff. Had a laugh reading this thread.

follow up question:

donating sperm?
lets say, euhm …twice a day?

You do realize that when people say they want to lose weight, they mean in body fat, don’t you? You are aware, of course, that the actual number on the scale means nothing? I fail to see how donating blood will help you remove body fat, even if it did lower your scale weight by a measurable amount.

maybe a better question would be how many calories does one burn when donating blood(or does how many calories does one burn replenishing the donated blood)

better?

As mentioned in the Column linked to above

So some, but not much. Donating every eight weeks means that you would give up the equivalent of 1 lb of weight per year. Subtract from that the juice and cookies you eat while recovering and it’s probably a wash.
