NCT00850629

Brief Summary

The investigators here propose to perform a collaborative clinical research effort including a randomized controlled trial investigating the mechanisms of weight maintenance and their relation to a lifestyle intervention in children, adolescents and adults. The detailed investigation and analysis of the variability and dynamics of the endocrine circuits responding to a negative energy balance and weight loss will be accompanied and enhanced by specific clinical projects targeting peripheral and central-nervous aspects of hormonal counter-regulation after weight loss. Mechanisms of endocrine counter-regulation and potential therapeutic approaches will be studied.

Outcome Measures

Primary Outcomes (1)

  • BMI will be assessed during lifestyle intervention in (1) children and adolescents and (2) adults vs. placebo

    BMI (kg/m2) will be analyzed after intentional weight loss in two comparable parts of a randomized controlled trial including (1) children and adolescents and (2) adults. Therefore effects of a multimodal lifestyle intervention will be compared to placebo.

    21 months

Secondary Outcomes (33)

  • Evaluation of leptin during lifestyle intervention

    month -3, month 0, month 12, month 18

  • Evaluation of leptin during follow up

    48 months

  • Evaluation of catecholamines during follow up

    48 months

  • Evaluation of catecholamines during lifestyle intervention

    month -3, month 0, month 12, month 18

  • Evaluation of cortisol during lifestyle intervention

    month -3, month 0, month 12, month 18

  • +28 more secondary outcomes
