There’s a growing debate about whether obesity is fuelled by lifestyle or simply by genetics.
Obesity: lifestyle or genetics?
Obese people are often branded overeaters who don't exercise. But many obesity experts argue that being heavily overweight is a common genetic disorder – and in evolutionary terms, it is much more natural than being thin.
In fact, one Australian obesity expert puts this twist on the issue: having a tendency to be overweight may well be a sign of superior breeding.
Professor Lesley Campbell, of the Garvan Institute's Diabetes and Obesity Research Program, says: "It can be argued that people predisposed to store fat are the lucky ones and the scrawnies have defective genes.
"People who today may become obese were built to survive times of famine, to ensure the survival of the human race. The scrawny ones wouldn't have lived."
Campbell may be citing a popular, if controversial, evolutionary argument, but whether it is supported or not there is a growing body of research which suggests our genes play a significant role in our risk of becoming overweight or obese.
In the family way
It is believed that the vast majority of people – some researchers estimate as many as 80 per cent – have inherited genes that predispose them to storing fat for a possible upcoming famine.
With the latest Australian figures showing 61 per cent of adults are overweight or obese, it's a hypothesis that could have some merit.
Professor Paul Zimmet, an international diabetes and obesity expert from Baker IDI Heart and Diabetes Institute in Melbourne, says the hereditary factor is a major player in obesity.
Zimmet believes genetics are responsible for at least 50 per cent of all obesity cases. Like Campbell, he believes obesity is often a genetic disorder – along the lines of depression or high blood pressure – and that it needs to be treated as such.
"It's not just one gene responsible for the current obesity epidemic, but as many as 30, and we need to understand that so it's not a case of pointing a finger at an individual," he says.
"Society must stop being so judgmental without even knowing a person's background. Assuming someone is fat because they're lazy or eat too much is just plain nasty."
Sorry that did not copy and paste too well. What this means if true is that some of us have to work MUCH harder to maintain a healthy weight than others and therefore people should not be so judgemental about people who are more overweight than them.My weight has been a lifetime struggle for me and the only time I was what most people would consider a healthy weight I was actually making myself sick after family meals. Just don't be too quick to judge others and don't assume we are all the same. Wouldn't life be boring if we were?
