I would think the infamous spark fat project where 2 people gained 30lbs in 30 days would be pretty good evidence for the possibility.
Only one person managed it. The female, whilst keeping up with the male in terms of % body fat increases, and being tall for a female, didn't make it to 30 in a month.
It is very difficult to do. Almost 1/4 addition to body weight but with the added problem of a digestive tract not used to the volume of food, and other psychological and physical reasons why the person was thin in the first place.
