You burn about 650 calories by donating one pint of blood.
Is the 650 calories burnt or lost, or is it that it takes 650 calories to replace the pint of blood or does the blood taken = 650 calories in value?Its a confusing and maybe misleading statement by the Mayoclinic as it seems odd that you can burn calories just by donating blood. I now wonder about the ethics in the statement. Is it a way to increase blood donating maybe? by making people believe that by giving blood you would burn calories and thus lose weight. However, by donating a pint you will lose somewhere around 570g in weight but the blood lost gets replaced quickly.Personally, I think reducing the calorie intake would be a better way to lose calories and that donating blood to do so is a drastic measure.
