[originaltext] Rising levels of obesity and unhealthy weights could be linke

Rising levels of obesity and unhealthy weights could be linked to 670,000 extra cases of cancer in the next 20 years, a UK report predicts.
    If current trends continue, experts say, almost three in four adults could be overweight or obese by 2035, bringing a host of health issues.
    Their work suggests a rise in the number of people who are overweight or obese would contribute to 4.6 million additional cases of type-2 diabetes and 1.6 million extra cases of heart disease by 2035.
    The report recommends a number of ways to tackle this problem, including introducing a 20 pence per litre tax on sugary drinks and a review of how food is advertised online.
    Department of Health officials said they had already brought in a ban on adverts featuring junk food during children’s TV programmes and would be launching a childhood obesity strategy shortly.
