Supersize us: upselling is fuelling the obesity epidemic, warns report

Consumers persuaded to scale up a meal or drink take on an extra 55% more calories on average - and a big annual weight gain, experts reveal

One in three people buys a larger coffee, more fries or added cream each week as a result of "upselling", which experts say is fuelling the obesity epidemic.

Most people in the UK - 78% of those questioned in a survey - say they are asked in restaurants, fast food outlets and stores at least once a week if they want to "go large", opting for more food or bigger portions, according to a report.
