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. The investigators 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. 3.How does gender and age influence the capacity to maintain the lifestyle induced adaptation in muscle and adipose tissue and maintaining weight loss?

Study Arms (1)

Intensive Lifestyle Intervention

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

Behavioral: Intensive Lifestyle Intervention

Interventions

Intensive Lifestyle Intervention 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.

Intensive Lifestyle Intervention

Eligibility Criteria

• Age: 18 Years - 65 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Former participants of Ubberup Folk High School will be included in this study. Ubberup Folk High School is a privately hold externate that teaches lifestyle intervention courses with focus on weight loss. A stay at Ubberup has a duration of 10-14 weeks and is primarily self-financed. The study population will consist of men and women of two different age Groups (18-35 and 35-65yr). We will recruit participants who succeeded in maintaining the weight loss and participants who regained in weight.

You may qualify if:

• Former participants of Ubberup Folk High School

You may not qualify if:

• Gastric Bypass Surgery or Gastric Banding
