Elizabeth Boivin

Pounds Lost: 8

The details: Boivin learned about the value of legumes and tofu, and started preparing vegetarian meals. She also planned girls' nights out that involved gym workouts and saunas rather than dinner and a movie, and dates with her husband that included some type of exercise.

New attitude: "I've lost 8 pounds, but who cares?" says Boivin. She's more excited about being a good role model for her two daughters.
