- Changes in microarray gene expression profiles in blood and subcutaneous abdominal fat tissue from healthy obese men, as a consequence of changes in dietary macro nutrient composition. [ Time Frame: Four weeks ]
- Time to stabilization of gene expression changes due to dietary intervention. [ Time Frame: 0, 1, 2, 7, 14 and 28 days ]

All participants underwent the same dietary intervention
Other: Balanced macronutrient diet intervention
Isocaloric dietary changes from typically Western diet to balanced macronutrient composition.
Other Name: Microarray study of diet intervention
Common for many of the risk factors of lifestyle diseases is that they are induced by improper diet. Recent research has shown that especially total amount and composition of the macro nutrients, protein, carbohydrate and fats, is important.
A time course experiment has been performed where 5 subjects underwent a diet intervention for four weeks with a controlled, balanced macro nutrient energy content of every meal. The sampling time points were 0, 1, 2, 7, 14 and 28 days. The goals were to determine optimal length of intervention with stabilization of gene expression to occur and compare blood and subcutaneous abdominal fat tissue as source of biological material for RNA for DNA microarray analysis. Microarray analysis were performed on 3 of the 5 subjects.
