i can't speak for ile/sei but in my experience i was frustrated in a relationship where i was trying to lose weight but it was always a struggle to get healthy food in the house because my ex would insist on buying the higher calorie foods and the junk foods and then tell me, "just don't eat as much," or "don't snack, only eat during meals," etc. and i wasn't able to do anything about it until i started buying all my own food and preparing two different meals and whatnot. because he thought he knew all the answers and wasn't willing to work with me. so i think its important to help her on her terms. she IS onto something with it being about the quality of the food she eats and not just about eating less. it might help if you're willing to sacrifice a little too and not just be like.. a motivational speaker, all self righteous and whatnot.
