Tag: Blood donation calories

According to research from the University of California, San Diego, your body can burn up to 650 calories during the process of replenishing the blood components lost, making it an interesting metabolic response. This means that the answer to how many calories do you burn after donating a pint of blood is significant, although it is not a direct or instantaneous effect.

Donating a single pint of blood can prompt your body to burn an estimated 600–650 calories, but this energy expenditure is for the production of new red blood cells, not a reflection of the blood's intrinsic caloric content.
