Actually, its worked out ok for my son and I. Since he really seems to like some of my low carb foods (esp. things like cheese cubes, roasted chicken, etc) I am just buying more of those and less of the junk snack foods I used to buy for him, so in essence, I'm replacing some of his bad foods with good stuff. But I can see where if you were a student and not a head of household it would be hard to buy for everyone on a limited income. Maybe a family meeting is in order. Maybe they can all chip in on groceries with you, or pledge to leave your stuff alone.
