There are two factors to consider whole blood or plasma donation? In the united states you can only donate whole blood once every 56 days due to the time your body needs to replace the red blood cells. I think that would be the type that is approx 650 calories to replace. Plasma would be significantly less I think due to the fact that its mainly comprised of water, platelets, and nutrients. Anyways the Gatorade they give you usually with the donation should cover the initial caloric loss.
