Comments like fashion designer Karl Lagerfeld's claim that singer Adele was a 'little too fat' change people's views, a study suggests.
a study of more than 90,000 people, they found women's knee-jerk anti-fat attitudes increased after a high-profile fat-shaming event.
Adele, pictured at the Grammy Awards in 2017, was called 'a little too fat' by the late fashion designer Karl Lagerfeld – scientists found high-profile fat-shaming changes women's attitudes  Recent examples have included a blogger saying Oscar-winning actress Jennifer Lawrence no longer looked 'hungry enough' to star in a movie The Hunger Games.
A fashion critic said of Mad Men star Christina Hendricks that 'You don't put a big girl in a big dress.
And 'shock jock' DJ Howard Stern called Lena Dunham, star and writer of Girls, a 'little fat chick'.
In the fortnight after these comments, and others like them, women had more negative attitudes towards fat people, scientists found.
This was judged in an online experiment which asked them to categorize silhouettes of body sizes and negative or positive words.
Amanda Ravary, lead author of the study from McGill University in Canada, said: ' It is hard to escape these fat-shaming messages, and our research suggests these messages that "fat is bad" not just affect the celebrity target, but can also influence other women who hear about the comments. still we hear these things and often do not bat an eyelash.
'Prejudice towards people because of their weight is one of the last remaining forms of socially acceptable discrimination.'
The Canadian researchers searched for articles on fat-shaming from magazines, newspapers and internet blogs between 2004 and 2015.

They then compared women's scores in a test of prejudice towards fat people, both in the two weeks before these episodes and the fortnight afterwards
This test for automatic prejudice was based on women categorizing silhouettes of bodies as fat or thin, and words like 'awful' or 'glorious' as positive or negative.
Sometimes they had to use just one letter on their keyboard to identify either a person or a good word, which made the task harder for women who were unconsciously believed to have been linked to bad words.
If they responded more slowly, this suggested greater prejudice.
In the two weeks after each of the fat-shaming cases in the study, women showed more bias towards fat people in this test.
When asked explicitly how much they preferred thin people to fat people, or how warmly they felt at both, women showed no difference after fat-shaming events.
Professor Jennifer Bartz, a senior author of the study from McGill University, said: "These cultural messages appeared to augment women's gut-level feeling that" thin "is good and" fat "is bad."
"These media messages can leave a private trace in peoples' minds."
