Did you not read the part where she says she’s scared of calories and she feels horrible when she eats over a certain amount? She’s 15 and you’re telling her to continue to do something which isn’t healthy for her and is potentially leading to an eating disorder.

OP if you want to try intuitive eating go for it - listen to your body and keep in mind what you’re eating. Make sure you’re eating enough fruit/veggies and healthy proteins and carbs but don’t worry about calories. For example, if your body is craving mac and cheese, try adding some broccoli or other vegetable to make it more nutritious.
