Does blood donate make us gain weight?

[shar_ila]

hi, i like to know wether does a person gain weight after they donate their blood?

after donation, you will lose weight since you just gave away 450 ml of blood. the appetite after the blood donation will be better than usual but it will tone down within 1 to 3 days. so there won't be much weight increase unless psychologically, you think you must eat a lot after the blood donation to compensate :D

You lose 610g to be precise.
