The former advertising agency finds that junk food advertising has become a "monster".
The founder of Living Loud UK, which encourages people to live a healthier life, Dan Parker is concerned that advertising of unhealthy foods and beverages has become more assertive.
"Ads have changed so content that kids and adults do not even know they're being advertised," he said.
Parker, who worked with major food companies before the development of type 2 diabetes mellitus, spoke of launching the Irish Heart Foundation (IHF) Stop Targeting Kids campaign.
The Foundation has found that seven out of ten adults here endorse a direct ban on promoting unhealthy foods and drinks for children.
Nearly eight out of ten adults believe that advertising is a major factor in overweight children, which is almost nine out of ten people as a major concern.
Parker said that junk food marketers have gone to extraordinary times to influence children's food choices.
"Junk food has become a monster, manipulating the feelings of young people," he said.
The explosion of digital marketing and the blatant exploitation of the junk mail delivery rules meant that children were bombarded daily with no objection to the ads.
"But there should not be situations where child-directed junk food is acceptable," Parker said.
The petition at irishheart.ie/stoptargetingkids urges the government to regulate digital marketing for Irish children and restrictive "broadcasting restrictions".
Irish Broadcasting Bureau forbids junk food advertising in 2013 in children's programming, up to six when children account for 50 per cent of the audience.
Settings do not work according to IHF, as children under thirty five still see more than 1,000 food information annually on Irish TV every year.
IHF has called for a ban on waterways at 9 pm, as many children watch television at 18-18, although they do not account for 50 percent of the audience.
