Global overeating has become a bigger problem than world hunger with more people now obese than underweight, the biggest ever study of worldwide trends in body mass index has revealed.

And it’s only going to get worse, the research, published in British medical journal The Lancet on Friday, says.

Over the past 40 years, the rate of obesity has increased 2.6-fold and the number of obese people worldwide has blown out from 105 million in 1975 to 641 million in 2014, the study found. Nearly 13 per cent of the global population is now obese, compared with just over 9 per cent who are underweight.
