Normalization of 'plus-size' risks hidden danger of obesity ... read more
June 22, 2018
New research warns that the normalization of 'plus-size' body shapes may be leading to an increasing number of people underestimating their weight - undermining efforts to tackle England's ever-growing obesity problem. Analysis of data from almost 23,460 people who are overweight or obese revealed that weight misperception has increased in England. Men and individuals with lower levels of education and income are more likely to underestimate their weight status and consequently less likely to try to lose weight.
