The Zone is one of the hottest diets out there ... that is, if you think having a long list of celebrity endorsements makes something 'hot'. So it's not surprising that another celebrity has jumped on the bandwagon that helped maintain the petite figures of Renee Zellweger and Jennifer Aniston by signing up for the plan. Natasha Bedingfield, the artist behind the song 'Unwritten' has made a typical 'popstar' move by going on the Zone and in a world where a few pounds can mean the difference between success and failure, I can't say I blame her for submitting to the 'fad'. In addition, she claims to have bags of pre-made, pre-measured food delivered to her, making it awfully easy for her to follow the diet.

What do you think of the Zone? Fad or fab?
