Cut back on the portions of the nuggets, replace the the fries with some salad (with a spare-to-moderate helping of dressing), replace the soda with unsweet tea, add some beef, and get enough exercise and it isn't a terrible diet. Trying to go full abstinence on the nuggets will probably fail because her stupid mother's years of neglect. Of course, she should learn now how to save money by doing it at home.
