The maker of the show, Celador, has licensed snack manufacturer Sun Valley to produce You Are What You Eat-branded packs of seeds, nuts and fruit mixes that follow the diet guidelines of the successful Channel 4 series.
PR shop Mason Williams has been brought in to promote the products, which will launch in mid-April.
The range will be aimed mainly at women, but also men, who want healthy snacking 'on the go'.
The agency, which won the communications account after a three-way competitive pitch, will handle trade and consumer public relations.
'These are all-day nibbling snacks that are a healthy alternative to chocolate and crisps,' said Sun Valley marketing manager Jonathan Barr.
The range will be sold in supermarkets such as Asda and Spar and off-licences, with a starting price of 99p for 100g bags.
