Dr. Oz and 'The Biggest Loser' trainers: Secrets to weight loss success

Every season, viewers watch as contestants on "The Biggest Loser" sweat, puff, huff and cry their way to weight loss success. Now Dr. Mehmet Oz has designed the ultimate show for viewers who have envied those contestants for their 24/7 access to celebrity personal trainers like Bob Harper, Dolvett Quince and Jillian Michaels. Featured on his Jan. 4 show: Behind the scenes of "The Biggest Loser" with those star trainers and their success stories. Just how have those past winners kept off the pounds - and how can you copy their success at home? Get the skinny now.

Through thick and thin (literally), Bob Harper has been the go-to trainer for "The Biggest Loser" contestants who want someone combining the qualities of your best friend, your favorite high school teacher and your fitness idol. Bob, who recently authored "The Skinny Rules: The Simple, Nonnegotiable Principles for Getting to Thin," emphasizes a key lesson when it comes to losing weight and keeping it off: Don't drink your calories. It's all too easy to waste excess calories on fattening beverages, such as a 600-calorie latte. In addition, use fiber to fill yourself up, not out, by enjoying fruits such as berries and veggies such as leafy greens.

Author of "Master Your Metabolism: The 3 Diet Secrets to Naturally Balancing Your Hormones for a Hot and Healthy Body!" and creator of the extreme weight loss kit "Body Revolution," Jillian Michaels believes that you can't succeed without counting calories. The secret: Don't get too low. Depending on your height, women should eat a minimum of 1,200 calories daily, while men should aim for 1,600 or more. However, Dolvett contends that the quality of those calories plays an important role, and he recommends enjoying lean protein and veggies.
