Overweight and obese people are usually viewed negatively. As well as being held up to ridicule, obese people are also subject to discrimination and anti-fat bias.

If Marilyn Monroe were an aspiring young actress today, she would be deemed too chubby for Hollywood. Her legendary figure fit the 1950s ideal of female beauty but since then curves are out - thin is in.

The size of aisles and seats in buses, airplanes, cinemas and waiting rooms are all suited to people with a slim build, while fashionable clothing seems to be designed only with the slim in mind. Each day large people get the message that they are not desirable or 'normal'.

We assume that thin people are successful, sexy and happy while large people are ugly, unhealthy and undesirable. The 'fat person' stereotype is that they are lazy and slothful. People's size can affect their chances of getting a job, being accepted in higher education, and the salary they receive.

Our stereotypes have a long history. Take Shakespeare. Julius Caesar refers to Cassius's "lean and hungry look", evidence of his ambition and plotting; in 'Henry the Fourth part 1', Falstaff is the continual butt of Prince Hal's jokes: having double-crossed him in a highway robbery prank, the Prince laughs as Falstaff flees in panic:

...Falstaff sweats to death,
And lards the lean earth as he walks along:
Were't not for laughing, I should pity him.

Throughout most of history, female fat has been a signal of fertility and sexuality. The most famous early image of a woman is a small figurine known as the Venus of Willendorf, which is thought to date between 24 000 and 22 000 BCE. And she is very large indeed - obese by our standards.

So, if they are lucky, large females may be 'cuddly' or an 'Earth Mother'. More often, though, 'they have let themselves go'.
