Now I have another idea, and this time I am inviting suggestions about where the story can go. It's something different for me (soliciting ideas like this), so let's see how it plays out.
The idea: the mother of a teen girl isn't happy about how her daughter has been overeating and getting fat lately, and wonders why her daughter's friend(s) also seem(s) to be getting fat. One of her friends suggests her daughter and her friend(s) made a pact to get fat, not unlike stories about friends making pacts to get pregnant. The mother doesn't dismiss this idea, but it doesn't help her figure out how to put a stop to her daughter's actions.
Now, the teen and her friend(s) are intentionally trying to get fat, encouraging and competing against each other, but the mother doesn't know this until later on. What she does know is that her parents, the teen's grandparents, are spoiling her and facilitating her gluttony and weight gain. They aren't bothered by how big their granddaughter is getting, which is confusing and a bit infuriating to the mother.
Not sure how to work this in, but everyone involved (the mother and grandparents) are well off, so this explains how the girl can be pigging out all the time (gifts of money from her grandparents, or them buying food for her when she visits them), and it takes care of any 'realistic' problems like buying new clothing.
That's all I have. Level of growth, rate of growth, the direction the story takes, that's all up in the air.
Any thoughts?
