Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

The investigators have the following research questions:

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

The study design is cross-sectional and will be based on a lifestyle intervention, as it is practiced in a real life setting at Ubberup folk high school. The investigators will recruit former participants of this lifestyle style intervention. 50 % who maintained a weight loss and a healthy life style and 50 % who did not.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intensive Lifestyle Intervention

Former participants of Ubberup Folk High Schools intensive lifestyle intervention programme.

Intensive Lifestyle Intervention

Intervention Type BEHAVIORAL

The included subjects has previously participated in the Intensive Lifestyle Intervention intervention at Ubberup Folk High School. This intervention includes daily exercise and a hypocaloric diet (app. -700KCal/day) for 10-14 weeks. Furthermore theoretical and practical education within e.g. Nutrition, exercise and motivational psychology.
