Current Primary Outcome Measures  ICMJE
 (submitted: June 27, 2013)		 Lipogenesis [ Time Frame: After total 6 weeks dietary intervention ]
Measurement of lipogenesis is based on i. v. administration of stable isotope labelled acetate (1,2-13C-acetate). 13C incorporation into palmitate is quantified by mass-spectrometry. 13C incorporation correlates to the rate of fatty acid synthesis.
Original Primary Outcome Measures  ICMJE
 (submitted: November 26, 2012)		 Lipogenesis [ Time Frame: After total 8 weeks dietary intervention ]
Measurement of lipogenesis is based on i. v. administration of stable isotope labelled acetat (1,2-13C-acetat). 13C incorporation into palmitat is quantified by mass-spectrometry. 13C incorporation correlates to the rate of fatty acid synthesis.

Descriptive Information
Brief Title  ICMJE Sugar Sweetened Beverages (SSB)- Effects on Metabolism
Official Title  ICMJE Effects of Carbohydrate Containing Diets on Lipid Metabolism & Fatty Acid Oxidation in Healthy Young Men - a Randomized, Double-Blinded Study.
Brief Summary The objective of this study is to investigate the impact of sugar sweetened beverages on the fat metabolism of healthy young men. It is well known that consumption of beverages sweetened with fructose is associated with different health risks such as type 2 diabetes. The present study has been designed to dissect differences in the metabolic pathways of fructose and glucose, but also metabolic adaptations during fructose, glucose and sucrose diets. During a period of seven weeks subjects will consume either fructose, glucose or sucrose sweetened beverages or continue their usual drinking habits. During these seven weeks there will be different metabolic investigations using stable isotope tracers. First, the rate of lipolysis and beta-oxidation will be determined. Second, the rates of fatty acid synthesis will be measured. During all examinations there will also be substrate- and energy-utilization measurements by indirect calorimetry, blood analysis and morphometric measurements. Based on the literature main hypotheses are: Fructose enhances de novo lipogenesis postprandially and also in the fasting state significantly more than glucose by enhanced expression of lipogenic enzymes. Fructose decreases beta oxidation via downregulation of oxidative enzymes.
