NCT01354626

Last verified: March 2012
  Purpose

The objective of this study is to investigate the potential beneficial effect of increasing protein in the diet in order to decrease hepatic lipid accumulation on a high-fat diet.

The investigators hypothesize that increasing protein in a high-fat diet suppresses lipid accumulation in the liver, and that changes in (hepatic) fat handling underlie this reduced lipid accumulation.

Primary Outcome Measures:
  • hepatic fat accumulation [ Time Frame: baseline, 2 weeks, 4 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Biomarkers of liver function/hepatic steatosis [ Time Frame: baseline, 2 weeks, 4 weeks ] [ Designated as safety issue: No ]
    Biomarkers of liver function/hepatic steatosis: ALT, AST, C-reactive protein

  • Circulating cytokines [ Time Frame: baseline, 2 weeks, 4 weeks ] [ Designated as safety issue: No ]
    adiponectin, TNF-α

  • Postprandial lipid metabolism [ Time Frame: 2 weeks, 4 weeks ] [ Designated as safety issue: No ]
    Postprandial lipid metabolism will be assessed by means of a meal challenge with the use of stable isotope tracer

  • Glucose homeostasis [ Time Frame: baseline, 2 weeks, 4 weeks ] [ Designated as safety issue: No ]
    Glucose homeostasis will be assessed with the homeostatic model assessment (HOMA) index in fasting blood samples. In addition dynamic indexes will be determined from the meal challenge.

  • Adipose tissue gene expression [ Time Frame: 2 weeks, 4 weeks ] [ Designated as safety issue: No ]
  • Peripheral blood mononuclear cells gene expression (PBMC's). [ Time Frame: baseline, 2 weeks, 4 weeks ] [ Designated as safety issue: No ]
