Running for four weeks from 1 October, the £2m TV work supports the brand's entry into the crisp market with Ryvita Limbos.
The ad, created by Mortimer Whittaker O'Sullivan, will highlight that Ryvita Limbos are baked, not fried and are only 3% fat. In comparison, Walkers' lower-fat offering, SunBites, contains 22% fat.
The execution features a snack pack race, overseen by Britton, which pokes fun at fatty, unhealthy crisps, representing them as sluggish sacks as they try to keep up with the energetic pack of Ryvita Limbos.
