The main antagonist could be a powerful sorcerer. As I mentioned before, in the context of a magical curse causing the weight gain. This sorcerer could have his own motives, like trying to take over the world by first weakening the Avengers' most iconic figure. He could use his dark magic to mess with Captain America's body and make him gain weight, and then use this as a distraction while he executes the rest of his evil plan.
Well, in the 'Captain America weight gain fanfic', it could be that he is mind - controlled to overeat. Imagine an enemy using some sort of mind - control device to make Steve Rogers consume large amounts of food. Or perhaps he's on a mission in a place where food is scarce, but when he finally gets access to it, he overindulges because of the long - term deprivation. This could lead to a significant weight gain. Also, it could be a story where he has to adapt to a new civilian life after a long time as Captain America and the change in routine and diet causes him to put on pounds.

Maybe it's an old enemy who has somehow survived and is now more powerful. They could be seeking revenge on Captain America for past defeats. For example, Red Skull could have found a new way to return and cause trouble.
