Abstract

INTRODUCTION:

The prevalence of overweight and obesity is escalating globally, and in Denmark more than 10% of the population are now severely overweight. The aim of this study was to estimate the short-term health effects of 15 weeks of intensive lifestyle intervention composed of physical activity, dietary changes and personal development in severely obese subjects of both sexes.

MATERIALS AND METHODS:

The 27 subjects were weighed weekly. Fat percentage, abdominal circumference, maximum oxygen uptake, heart rate, oral glucose tolerance and blood lipids were measured at baseline and in week 15. The intensive lifestyle intervention was completed under supervision at a stay at Ebeltoft Kurcenter, and the goal was a weight loss of approximately 1% per week.

RESULTS:

At baseline, the participants' average body mass index (BMI: kg/m2) was 44 +- 1; the BMI was reduced by 11% after the stay (p<0.001). Body weight was reduced by 14 +- 4 kg (p<0.001), corresponding to 76% of the desired weight loss. The subjects' fat mass was reduced by 4% (p<0.001), and their maximal oxygen uptake was enhanced by 25% (p<0.001). Concerning the blood lipids, total cholesterol was reduced by 8% (p = 0.03); there was no significant change in LDL level and a reduction of 15% (p<0.05) in HDL level. After the intervention, oral glucose tolerance was significantly improved (p<0.001).

CONCLUSION:

After 15 weeks of intensive lifestyle intervention, there were significant improvements in aerobic fitness and metabolic risk parameters, and the observed weight loss was equivalent to that obtained by surgical treatment. Decisive in the choice of obesity treatment will continue to be the extent of success in permanent weight loss.
