Ryvita is backing its new Minis low-fat bagged snack with a new TV ad starring Fern Britton as part of the brand’s £4m rollout programme.

In the ad, the head of the presenter of ITV’s This Morning has been superimposed on to the body of a former Miss UK.

Made to appeal to the brand’s target audience of weight conscious, but not diet-mad, women, the ad shows the perfectly shaped Britton eating a pack of the 3% fat Minis.
