There IS a genetic component involved in weight gain/loss. It's not so direct as flipping a "fat" or "not fat" switch, but it's still there. I don't really remember how it works, but it has something to do with the way your body stores energy. Exercise and dieting help, but if your body likes to store its energy as fat, it makes it a lot more difficult. It may be that Crohn's triggered a change in that gene.
Short of a lifestyle change, it doesn't sound like theres much you can do. If the weight isn't a danger to her health and she doesn't mind it, I'd say just drop it. Best you can do is keep an eye on it, encourage physical activity, and make sure it doesn't become a health hazard. Then, if she decides she wants to work on it, do what you can to help. It needs to be her idea, though.
Actually... thinking about
it, I have a paunch of my own because I generally dislike exercise. It's boring and feels like a waste of time (also my active Crohn's makes it painful). But... I don't mind working, even if its physically demanding. She's in remission now, try finding her a job! She's too young for the general workforce, but maybe a friend could use some help planting a new garden or something. And, there's always lawn-mowing. I made good money doing that, and with a push-mower, even one with self-propulsion, it's good exercise.
