    I had to give a pint of blood per week for 16 weeks, 2 gallons, and it didn't effect my weight at all so I don't think there is any truth to it. It takes 48 hours to replenish your volume and longer to replace platelets and hemoglobin but the only weight loss would be temporary from the 500ml removed.

    So much? We're only allowed 500 ml every 8 weeks of whole blood.
    It was due to a medical condition, hemochromatosis. My iron was at toxic levels in my organs and aggressively taking blood until the numbers get to normal is the treatment.

    I also have hemochromatosis and donated blood every second week for 18 months until my ferritin level was below 50.
    I didn't lose any extra weight.
    When my ferritin level reach 300+ I visit the hospital and donate 450 ml. about 3 or 4 per year.
