It's a "Tyra Show" movement--Get Your Shape in Shape! Talk-show host Tyra Banks is dedicating the entire hour to answering all questions and providing step-by-step tips on her healthy new lifestyle after being inundated with e-mails and letters from fans.

The former supermodel, who admits to being sent jeans that don't fit their previous owner and even a prepaid cell phone from a viewer asking her to call them and tell them how she lost the weight, informs viewers this is "not a diet," but "a lifestyle change."

"This is not a diet; I do not believe in diets. I have been on diets in the past and they are a bunch of bologna! This is a lifestyle change. It's not about being skinny, its about getting in the best shape that you can be," says Banks, who has publicly battled her weight. "This is a "Tyra Show" movement. If I can do it, and love to lay up and not workout and I love me some BBQ ribs and some ice cream and some Haagen Daaz, I can do this and you can do this and still eat what you want, just not every second. It is time to get your shape in shape!"

The talk-show host filled her entire audience with those who wrote in inquiring about her new lifestyle and is asking everyone to partake in her get fit and get healthy challenge.

The former top model, who calls her different measurements her levels, also says she still has maintained her "34DD boobies and her round booty."

Banks, who is joined by her nutritionist Heather Bauer, covers it all on this episode from love 'em and leave 'em carbs to fiberlicious foods, sample lunch and dinner menus, even which fast food choice is the best if you're on the go! Plus, meet the audience member teams who will be blogging about their get-fit journey on TyraShow.com. Tune in Wednesday, November 4, at 4 P.M. EST on the CW for the entire episode.
