The research found that fast food takeaways were most at fault for childhood obesity since one in four children ordered takeaway to their school.
The Royal Society of Public Heath (RSPH) have cautioned that this could result in a ban.
The survey, that was of 500 children, aged between 13-18, found that 25 per cent ordered takeaways to be delivered to their schools. In most of these cases, the children ordered it via smartphone.
The poll found that more than 40 per cent could easily walk from their schools to a fast food or sweet shop in less than two minutes.
The report, which comes before the long-delayed Government childhood obesity strategy, pursued the opinions of young people on the best ways to confront the issues surround obesity.
Suggestions comprised of loyalty cards which offered shoppers points for making healthy food selections, and encouraging supermarkets to give away fruit and vegetables that were too “wonky” to sell.
Other thoughts include “film-style classifications” such as PG, 12 and 15 on foods that are high in fat, salt or sugar.
Children also suggested that free wi-fi should be offered in healthy environments like parks, in order to prevent people from going to fast food restaurants or coffee shops in pursuit of free Wi-Fi.
Latest figures show that nearly one in five 10-11 year olds are obese.
The Government will be announcing a new approach that will endeavour to reduce marketing and advertising of unhealthy food, and price promotions on such products.
Shirley Cramer, chief executive, RSPH, said: “Our childhood obesity rates are disappointing, and tackling this must be a priority for government – there can be no excuses for fudging action on what is our number one public health challenge.”
She added: “While we welcome the Government’s introduction of a sugar levy on soft drinks, it is absolutely critical that the forthcoming childhood obesity strategy builds on this positive step with a basket of hard-hitting measures, from greater controls on advertising and marketing of junk food to food reformulation.”
Three quarters of parents surveyed by Populus, in a separate poll of 2,000 adults, supported the constraints on fast food shops serving children during school hours.
