DSD (17) has declared that she is now following a new diet that entails on alternate days of the week fasting by only eating one meal in the day (lunch). So every other day she's missing both breakfast and dinner.
I'm not happy about this. She's going on about the health benefits of this diet. But I don't think it sounds healthy and don't think it's a good example for the younger DCs to see her skipping meals. I don't really care if she skips breakfast but dinner is also a time we sit down together as a family.
Her weight is bordering on the overweight band so I'm not immediately concerned about her staving, but am fearful that this is part of an odd attempt to lose weight - she's a bit sensitive about her weight and says her Mum tells her she's fat. She lives with us every weekend and with her Mum in the week. I'm not sure what her Mum thinks of the fasting but their relationship is strained right now. My DH seems to be going along with it and I don't think feels that at her she he can force her to eat.
Would you let a teenage do this?
