More than half of all adults and a third of children, teenagers and young adults around the world are predicted to be overweight or obese by 2050, according to a study in The Lancet. Researchers warn that obesity levels are predicted to accelerate rapidly during the remainder of this decade, particularly in lower-income countries. The study predicts that China (627 million), India (450 million) and the US (214 million) will be the countries with the biggest populations of overweight or obese people in 2050. And population growth means that forecasters are predicting the number in sub-Saharan Africa will rise by more than 250% to 522 million.
