As the newest face of Weight Watchers, Jennifer Hudson has been making headlines everywhere for her amazing 80-pound weight loss.

We had the chance to interview the star and recent author of "I Got This: How I Changed My Ways and Lost What Weighed Me Down" at a cocktail party thrown by Good Housekeeping magazine. Watch the video above to see her interview, or read on for some of Jennifer's inspirational messages.

Amber: You've won an Oscar and lost 80 pounds. Which has been more rewarding?

Jennifer: For different reasons, they're all special. And I know I say I'm most proud of my weight loss — and I am — because it's helped (save) lives. Seeing people being inspired from there and changing, it melts my heart. It brings tears to my eyes every single time I have someone come over to me and say, "You helped save my life … Because of you and your journey, it inspired me with my journey, and therefore, I get not only to lose weight, but to add years back to my life, or have a healthier me."

Amber: Do you think overweight people get treated differently?

Jennifer: That is definitely true. I don't think you notice it until you've experienced the other side. You don't know what you're being discriminated against with, until you see what others get that you don't … and that's why I always say (that) you can never understand what I mean unless you've experienced what I've experienced.
