Health experts are calling for the government to take action on junk food marketing in the wake of the emerging link between obesity and death from Covid-19.
The Obesity Health Alliance, which is made up of 44 charities and groups, said policy changes were urgently needed to tackle promotions on junk food, such as buy one, get one free.
It carried out a poll of 2,085 people which found that 74% supported the need for further Government action on obesity.
Almost eight out of 10 (78%) supported manufacturers reducing sugar in foods, while 74% backed not showing adverts for junk food before 9pm on TV and online.
It follows a Public Health England (PHE) report on Tuesday which found that being obese increased the risk of dying from Covid-19 by 27% while being morbidly obese more than doubled the risk.
Caroline Cerny, alliance lead at the Obesity Health Alliance, said: "The Government can now feel confident that the game-changing policies needed to transform our environment into a healthier one are not only evidence-based, but also wanted by the majority of people in the UK.
"We are now calling on the Government to push ahead with a comprehensive plan to make it easier for us all to be healthier, now and in the future by taking unhealthy food out of the spotlight."
Some 72% of people in the Obesity Health Alliance poll supported restrictions on shops promoting unhealthy foods in prominent areas such as checkouts and shop entrances, while 62% wanted restrictions on promotional offers, such as buy one, get one free.
Just over six in 10 (63%) people wanted to see the sugar tax for soft drinks extended to other sugary and high calorie foods, such as sweets and biscuits.
John Maingay, director of policy and influencing at the British Heart Foundation, which is part of the alliance, said: "The potential link between obesity and coronavirus has rightly put the spotlight on the urgent need to address the causes of obesity and support everyone's health.
"This means starting from early in life. Children with obesity are more likely to develop heart and circulatory diseases later in life, and it is critical that we turn the tide on this disease at the earliest possible opportunity.
"We know that the environment we live in has a bearing on all our health, and the Government must revive existing plans to reduce salt, sugar and calories in our everyday foods, limit advertising of junk food to children and ensure that people aren't inundated with promotions for unhealthy food and drink."
