If your roommate was sabotaging your diet? She's more overweight than you and complains about her own weight, and she knows you're dieting, but fixes huge, unhealthy meals, cakes, and buys pies multiple time a week, then offers you some. You've told her that makes it really hard for you to stick to your diet and asked her to make smaller portions, or keep things like cookies in her room, but nothing has changed. Before you got the roommate you had lost 60 pounds, now you're gaining weight. This is happening to someone I know. What would you do? Don't say have more willpower. She doesn't have any willpower. She's addicted to food. I've gone to their house and made healthy meals for her to try and help out and the roommate will go behind me and bake a cake.
