This week is National Healthy Weight Week (22 -29 January 2012) and QIMR would like to showcase some of our research on healthy weight.
Increased cancer risk
Compared to people who are obese, people in a healthy weight range are less likely to develop oesophageal cancer according to research conducted by the Queensland Institute of Medical Research and published in the scientific journal Gut.
People who were clinically obese (body mass index (BMI) of 40 or more) were six times more likely to have cancer of the oesophagus compared to those with a BMI between 18.5 and 25.
The science behind it
Higher levels of fat tissue in the body boost insulin production, which in turn increases the amount of circulating insulin like growth factor. Both these hormones stimulate cell growth and curb cell death, conditions which favour the development of cancers.
