By ‘weight gain’ I mean weight that would be retained once the food/liquid has passed. So muscle mass and fat gained.
(Simplified) The upper threshold of weightloss is calories in calories out. If I eat nothing in a day I will lose the amount of weight my body burned. Approx 3500cal/lbs.
What is the upper threshold of weight gain? I presume my body can only produce so much muscle and store so much fat in a given time period. If I managed to stuff 35,000 calories down my gullet, I wouldn’t gain 10lbs. Most of it would pass unused.

Are you talking about a one-off ‘back to fighting weight’ sort of gain? If so are you starting from a fully depleted state? I’d think that with medical grade rehydration techniques you could probably put on 10-15 pounds in a day and hold onto it for a while, but that’s after drying way out so you’re really just putting that all back.
