Reply to comment by gasparaspo in TIL that blue whale calves can drink 60 gal / 225 liters of milk a day and can gain up to 8 lbs / 3.7 kg an HOUR. by persondude27

That... almost makes it seem reasonable! 21 feet long at birth, so basically the size of a Ford F-350 pickup.

Humans can gain and lose up to 5% of their body weight in a day depending on their intake and exertion.

Professional athletes are on that extreme, and more current trainer care makes it less likely, but American Football Lineman, and professional Hockey goalies can swing up 10lbs/5kg of body weight during a game.
