Eighty per cent of men and almost seventy per cent of women will be overweight by 2020 according to a study by Oxford University’s Professor Klim McPherson.

Unlike childhood obesity rates, which according to a previous study have now peaked, adult obesity is expected to continue to rise.

The study predicts that 41 per cent of men aged 20 to 65 will be obese by 2020, along with 36 per cent of women.

McPherson stated, “We are being overwhelmed by the effects of today’s ‘obesogenic’ environment, with its abundance of energy-dense food and sedentary lifestyles.” He warned, “The Government needs to redouble its efforts to tackle obesity.”
