Obesity can lead to many risks such as type 2 diabetes (external link) and heart disease. Eating healthily and exercise are encouraged.

At the same time, the University of Stavanger (UiS) study reveals that psychological stress of physical exercise can explain the lack of motivation and the mental impact exercise has on the overweight.

UiS Department of Health Associate Professor Rynjar Foss is one of the lead authors among the four scientists who were responsible for the study.

“It's often said obese people should change their diet and exercise to lose weight. But they may also need to deal with stress, he said.

The “Exercise Can Alter Cortisol Responses in Obese Subjects” study was published online in the Journal of Exercise Physiology in February.

17 inactive people with a body mass index (BMI) more than 35 took part in the programme for 22 weeks to support the research. They became more active as they participated in exercise, diet and seminars.

Results from the research revealed that the participants lost less weight than expected. The scientists believe this could be related to cortisol, a hormone in the body secreted by the adrenal glands commonly known as the ‘stress hormone’.

Participants’ stress levels increased, with research suggesting that the high amounts of stress made weight loss more difficult.  

Furthermore, those who took part were still affected six months after the 22-week programme ended. This is because levels of cortisol were retained, and those who had lost the most weight had the lowest amount of cortisol.

Numbers of overweight people are constantly increasing. The World Health Organisation reports more than 40 million children below the age of 5 were overweight in 2011. Moreover, obesity levels have nearly doubled worldwide since 1980.

Norwegian health authorities have forecast that one in four children could be overweight in fifteen years, with Norwegians losing the fight on fat.

Physiotherapist Martha Loland, who conducted the study for her MSc in health science at the UiS, said that “if you’re physically active, you can be in good health even if you’re overweight.”

“The chances of suffering cardio-vascular disease are smaller for obese people who exercise than for those who don’t make any effort to keep fit,” she added (external link).
