By the end of the year, all advertising and packaging for selected cereals will feature a 'Calories in, calories out' message, designed to encourage consumers to live a healthier life.
All future products and innovations for children and families will be developed with this strategy in mind.
A Kellogg spokeswoman said each cereal would convey the calories message in its own way. Frosties, the UK's fourth-biggest-selling cereal brand, already uses the strapline 'Train hard, eat right, earn your stripes', which was created as part of the strategy. The company has yet to decide whether to develop a logo specifically for on-pack use.
Last week the cereal giant introduced a reduced-sugar version of Frosties.
The reformulation cut the cereal's sugar content by one-third, and led to the company claiming that 30g of Frosties contains less sugar than a small banana.
Frosties was mentioned as one of the worst offenders in the Consumers' Association's cereal report at the beginning of the year, due to its high levels of sugar and salt and its low fibre content.
Earlier this month Kellogg revealed details of a £3m All-Bran promotion, intended to communicate the health benefits of fibre.
As part of the push, Bran Flakes and Sultana Bran will be rebranded to form part of the All-Bran range (Marketing, 4 August).
Rival cereal firm Quaker is this month introducing its first extension to its Sugar Puffs brand in 50 years.
Honey-flavoured HM's, named after Sugar Puffs' icon, the Honey Monster, will be backed by a £500,000 TV campaign. Quaker expects HM's to grow the Sugar Puffs brand by 20% in its first year.
