  • Biomarkers of liver function/hepatic steatosis [ Time Frame: baseline, 2 weeks, 4 weeks ]
    Biomarkers of liver function/hepatic steatosis: ALT, AST, C-reactive protein
  • Circulating cytokines [ Time Frame: baseline, 2 weeks, 4 weeks ]
    adiponectin, TNF-α
  • Postprandial lipid metabolism [ Time Frame: 2 weeks, 4 weeks ]
    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 ]
    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 ]
  • Peripheral blood mononuclear cells gene expression (PBMC's). [ Time Frame: baseline, 2 weeks, 4 weeks ]

Dietary Protein and Hepatic Fat Accumulation
Influence of Increasing Dietary Protein on Hepatic Fat Accumulation and Postprandial Metabolism

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.
