Clinical Trial Summary

The purpose of this study is to investigate dietary compositions effect on liverfat measured by magnetic resonance imaging.

Description:

Overweight but otherwise healthy men will be included in the study which is a randomized diet intervention study in a cross over design. The study involves 2 intervention periods of 5 days each, during which the participant ingests two different types of experimental diet. Participants will in randomized order (determined by block randomization) ingest a diet with low carbohydrate and high fat content, and a diet with high carbohydrate and low fat content.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Liverfat	The effect of high-carbohydrate/low-fat vs low-carbohydrate/high-fat diet on change in MRS determined liver fat.	(MRS Day -1 (before intervention starts), Day 5 (after diet intervention is completed)
Secondary	Glycogen	effect of the low-carbohydrate/high-fat intake and high-carbohydrate/low-fat intake on hepatic glycogen content measured by 7T 13C-MRS	(MRS Day -1 (before intervention starts), Day 5 (after diet intervention is completed)
Secondary	fasting hepatic glucose output	measured by Ra of glucose= (infusion rate of 6,6 2H2-glucose)/TTR	(Day 0 and Day 6 of the diet intervention)
Secondary	fasting blood triacylglycerol concentration		(Day 0 and Day 6 of the diet intervention)
Secondary	Insulin clearance determined during steady state insulin infusion		(Day 0 and Day 6 of the diet intervention)
