How can I lose weight with all this food around me?

My mom is always making amazing cookies, brownies, and cakes. She always has candy in the house and she always buys ice cream. It makes it so hard for me because I’m trying to lose weight but she has all this tempting food ALL of the time! What can I do?? I’ve talked to her and she never wants to buy the healthy foods I need to lose weight. Thanks for your help!
