Do you have a job? If you're really bugged about the stuff your mom buys at the store, save up some money every week and use it to buy YOURSELF something at the store, something healthy that you'll actually eat. That's what I've started to with my mom. I can't eat half the stuff my parents buy, so I'm using about $10 every week to buy me something healthy (like nutragrain bars, or something) when we go to the store. Also, the walk around the store helps with exercize.
