It's true that Dustin and Becky have both gained a ton of weight since knowing Amber, but I blame them and not Amber. It's all about self-control. Both of them were overweight when they met Amber. They probably would have continued to balloon up anyway, just at a slower pace. If Becky wanted to lose weight, she could eat a small meal at home and then sit and have a drink while Amber stuffs her face in a restaurant. If that makes Amber unhappy, tough shit. After Becky's rant about not wanting to eat dessert alone at The Cheesecake Factory, I guess that wouldn't happen. But she could order off the children's menu, box up half of her meal to take home, or order an appetizer in place of a meal. None of the people associated with Amber practice self-control.
