Just in time for New Years resolutions to kick in, Oprah Winfrey is here to encourage you to try Weight Watchers.

She is part owner and celebrity pitchwoman for the company - and is a member herself. Shortly after joining forces with Weight Watchers she announced she'd quickly lost 15 pounds. ( She also gained an estimated $45 million ).

"Weight Watchers called me .. they said we'd like you to come aboard our program and do what you do: Self empowerment, self enrichment," Oprah said during a visit to Ellen DeGeneres' talk show last year. "We think you can bring another level to us for Weight Watchers. I said I can't do it unless I actually go on the program. I would have to do the program myself."

She's now lost about 40 pounds. In her latest update, posted right after Christmas, she was so overjoyed with her ongoing success that she broke into song.
