The partnership was officially announced at the unveiling of Nickelodeon's autumn/winter programming schedule last night (8 July).
The second largest commercial kids TV network in the UK will soon include Change4Life messages and branding in bespoke campaign spots.
The move complements the network's Nicktrition initiative, which it proactively launched in 2005 in response to growing concern about the health of children in the UK and subsequent Ofcom review of so-called junk food advertising.
Two new brand spots will air across the network from today (9 July) that endorse the importance of healthy, balanced eating and an active lifestyle.
Approximately 16 spots are expected to run on-air every day over the next 12 months, forecast to reach more than six million people within the first three months.
Howard Litton, managing director of Nickelodeon UK, called the initiative "a natural fit" with the network's Nicktrition campaign and stressed corporate social responsibility played a "core part of the brand".
He added: "We're in a great position to support the movement as we represent a unique and trusted voice among UK kids. We can use this voice to tackle issues in an effective and engaging way."
Change4Life is a national movement to encourage kids to "eat well, move more and live longer". It already has support from more than 18,000 grass roots organisations, ranging from charities and supermarkets to commercial organisations.
