Francesca Newland is unimpressed with Grey Worldwide's new Slim-fast spot: 'The bit that really gets my goat is when she says 'it's gorgeous'. Who is she trying to kid? A watery milkshake twice a day does not sound 'gorgeous' to me. The icing on the cake, however, is the scene of this real-life slimmer running down the beach in slow-motion. Advertising has got a lot more sophisticated than this. Slim-fast needs to catch up.'
