Sometimes people are just fat and happy - which is the sort of people Sally is most frightened of; those of us that stick two chubby fingers up to a world obsessed with the scrutiny of women's bodies, diets that promote starvation techniques and the idea that thinness is somehow related to successfulness. Obesity isn't curable if you don't want curing.
The connotations of fat are clear and calling someone so in an argument is really just making a sweeping generalisation and assertion about their character. As a society we believe that being fat equates to laziness, being unhealthy, unattractive, thick, unsuccessful and unpopular - it's little wonder that these three little letters are the go-to insult...
In the last ten years governments around the globe launched huge campaigns against the tobacco industry and rightly so. Holding a cigarette in the United States became such a taboo; you might as well be holding a gun instead! Sugar has become the new tobacco killer and governments have done very little, if anything at all, to tackle this problem. Why?
There is nothing new about our love of fat and sugar. We have a strong evolutionary drive to eat these foods because they are rich sources of calories which can be laid down as fat - which is simply stored energy. Our ancestors needed plenty of fat to fuel activity during periods of food scarcity and to pay for our large, expensive brains.
