How can I gain 4 pounds in 2 days?

QueenAmidala
I've lost 6 pounds since September and as I'm already slim, I don't want to be slimmer so, I'd like to know if it's possible to gain 4 pounds in two days and if it is, I'd like to know how.
I'm not afraid about eating too much, I perfectly know there are risks but, I just want to know how can I gain 4 pounds in 2 days.
Please?
