Hormonal Regulation of Body Weight Maintenance
perjantai 12. tammikuuta 2018 päivittänyt: Professor Joachim Spranger, Charite University, Berlin, Germany
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.

BMI will be assessed during lifestyle intervention in (1) children and adolescents and (2) adults vs. placebo
Aikaikkuna: 21 months
