Dietary Protein and Hepatic Fat Accumulation (LiF-Pro)
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.
