The three-minute ad created by Saatchi and Saatchi, which is Weight Watchers' biggest ad campaign to date, features Alesha Dixon singing a pop anthem about weight loss.
The behind-the-scenes footage features Saatchi and Saatchi's creative and art director Rick Dodds, speaking and directing the 180 women featured in the ad singing 'Do it our way' by Alisha Dixon, which plays out for the duration of the ad.
Weight Watchers members from all walks of life take turns to lip-synch the song lyrics which express their own personal stories.
Kate Stanners is the executive creative director on the ad working alongside Dodds and copywriter Steve Howell. The production company was Academy and the ad was directed by Si & Ad and Johnny and Jono.
The TV ad is to launch the brand's new "play" brand proposition, with the strapline "Weight Watchers, the game you play to lose weight".
Following the initial three-minute TV spot, the ad will be followed by a series of 30-second spots throughout January, featuring a run of separate "real life stories" of key members in the pop video.
