A Monash University-led nationwide study into the health beliefs and behaviours of obese people has found that the more severely obese a person is, the less likely they feel they can reduce their weight.

The research, funded by the Australian Research Council Discovery Grant Scheme, is the first of its kind in Australia. 141 obese Australians were extensively interviewed to try to gauge how they perceived their weight and ability to manage it.

"Severely obese individuals felt an urgent and desperate need to change their health behaviours, but felt completely powerless to do so. Most felt worried and scared about the potential health consequences of their weight. Most felt blamed and ashamed by public health and education campaigns about obesity, which did little to actually help them address their weight," Dr Thomas said.

Dr Thomas said in contrast, people whose weight fell within the mild to moderately obese range understood they were significantly overweight but did not believe they needed to lose weight to improve their health and wellbeing.

"Those individuals, with a BMI between 30 and 40, believed they could lose weight if they needed to, but did not feel this was an urgent health priority as most felt physically healthy," Dr Thomas said.

"Most of the study participants in this category deliberately sought to distance themselves from public health messages about obesity and the word obesity because of the social stigma attached to the condition. They also stigmatised those who were fatter than themselves."

Dr Thomas said it appeared the public health messages were not getting through to those who needed it most.
