The extra calories could mean a potential weight gain of five pounds, the report said.Young people aged 18 to 24 are the most likely to experience up-selling, with the study finding that they consume an extra 750 calories a week as a result, which could mean an annual gain of up to 11 pounds.The charity urged businesses to pledge to only up-sell healthy food and drink, and said shops should stop paying staff commission for hitting “up-selling” targets.The research found that those who were persuaded to supersize on average spent 17 per cent more for 55 per cent more calories, with special offers reserved for the least healthy fare. RSPH chief executive Shirley Cramer said: “Obesity is the public health challenge of our generation and if not addressed urgently could tip over the point of no return.”Almost everyone can relate to the feeling of being pressured into buying extra calories through up-selling.”The charity and diet company are urging consumers to use the hashtag #JustThisThanks to fight back against the trend, which the head of the NHS has previously described as “a form of health pollution”. On average, consumers will face 106 attempts at upselling a year, the study found Credit:Dominic Lipinski/PA Supersize tactics by retailers mean the average person is consuming an extra 17,000 calories a year – which could mean five pounds weight gain – health experts have warned.The Royal Society of Public Health said consumers are facing more than 100 attempts each year by shops and fast-food chains to “up-sell” unhealthy foods and drinks each year.The charity said soaring obesity levels were being fuelled by pushy sales assistants, trained to ask customers if they wanted to “go large,” upgrade to a meal deal, or add cut-price chocolate to their purchase.It urged retailers to stop linking staff pay to the success of efforts to pressure customers into buying more junk food.The report carried out with Slimming World, found that over the course of a week, “verbal pushes” meant 34 per cent of customers ended up buying a larger coffee than requested, with 33 per cent upgrading to meal deals, and 36 per cent adding chocolate to their shop.The report, from a survey of more than 2,000 UK adults, found that consumers face an average of 106 verbal pushes annually, which led to an extra 330 calories a week, or 17,000 calories a year.

“We should plant our standard squarely on preserving Bosworth and its heritage, both past and yet to be discovered.” “Bosworth is the battlefield under threat today; but while the current legal framework continues, no doubt there will be others,” Mr Skidmore will tell MPs at a debate in Westminster Hall today.”For to build over one part of a battlefield site, threatens to set a precedent of permissiveness that could erode our ability to protect our battlefields across the country.

Ancient battlefields will be at risk if building is allowed to go ahead at Bosworth Field, ministers will be warned today, as campaigners launched a bid to buy the threatened land for the nation. Chris Skidmore, a Conservative party vice chairman and leading expert on Richard III, will call for better protections for the 46 battlefields in England after automotive specialists Horiba Mira Ltd applied to build a test track for driverless vehicles on part of the site. The Battle of Bosworth in August 1485 was a crucial moment in British history which saw the death of Richard III, ending the Plantagenet reign and bringing the Tudor dynasty to the throne. More than 12,000 people have signed a petition urging Hinkley and Bosworth Borough Council to refuse permission for the new 83 acre test track, while The Battlefields Trust has launched a campaign to buy the land from Horiba Mira. Mr Skidmore will also call for the Government to tighten planning rules which currently only stop building on battlefields if there is “substantial harm”.He will add: “I know that this is a local decision that will be made by the Council, and I am sure that they will reflect upon the written submissions and petition next month. “But we must recognise here the precedent nationally that this application risks setting. “And we must also ask, how have we managed to get to this situation in the first place that a battlefield of national historic importance should be placed under threat?” The decision on whether to allow the test track to go ahead will be made by Hinckley and Borough Council on September 25. Bosworth FieldCredit:Royal Collection/Richard III’s body was discovered in Leicester The land in which the battle of Bosworth is set needs to be bought for the nation.Kelvin van Hasselt, vice president of The Battlefields Trust Kelvin van Hasselt, vice president of The Battlefields Trust, said: “The land in which the battle of Bosworth is set needs to be bought for the nation just as the Americans do with their battlefields “The wider battlefield faces a severe threat of building which will prevent its proper presentation in the future.“In particular it will not be possible to stand where Henry Tudor stood when he first saw Richard III’s army, ponder the decisions he then made and from there to walk in his footsteps to the point where the armies engaged.
