My mom is a picky eater, would rather die than eat a fruit or a salad or any raw vegetable, lives on a meat and empty carb based diet with lots of fat and sugar. She is 65, her bloodwork is horrible, she's out of shape, healthy BMI but super high bodyfat percentage. She has lost weight after health problems hit her (because she was barely able to eat) BUT I doubt that she'll do better without eating actually healthy stuff.
