The sassy host of The Talk revealed Tuesday that she's the newest celebrity ambassador of the Atkins diet, and although Sharon didn't disclose a number for her weight-loss goal, she's off to a great start having dropped 11 pounds already in just two weeks.

"I want to approach 60 the way I want to," said Sharon, who turns 60 October 9. The star dabbled with various diets (as well as lap-band surgery in 1999) in the past, and after having tried Atkins with great success this summer decided to sign on as spokeswoman. "It's the right blend of vegetables and protein for me."
