Brief Summary

In Denmark and the western world, there is an increasing prevalence of obesity probably due to a combination of inadequate daily physical activity and a high energy intake. One approach to achieve weight loss and change life style is to participate in an intensive supervised prolonged life style modification course. The immediate effect is often positive, but over time the overall effect is limited as the majority will not maintain weight loss and a changed life style. The purpose of this study is therefore to characterize the physiological factors that determine/influence the capacity to maintain weight loss and a healthy lifestyle after a prolonged lifestyle intervention. We have the following research questions:

  1. 1.Are there physiological traits and characteristics that mediate better adherence to lifestyle changes and weight loss?
  2. 2.Does the adaptation in muscle oxidative capacity after lifestyle intervention predict success in maintaining weight loss and lifestyle changes 3, 12 and 39 months after intervention?
  3. 3.How does gender and age influence the capacity to maintain the lifestyle induced adaptation in muscle and adipose tissue and maintaining weight loss?
