  Purpose

The purpose of this pilot study is to optimize conditions for a planned human intervention study focusing on how diet predispose for, and influence, lifestyle disease development and its consequence in cardiovascular disease development.

Further study details as provided by Norwegian University of Science and Technology:

Primary Outcome Measures:
  • 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 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time to stabilization of gene expression changes due to dietary intervention. [ Time Frame: 0, 1, 2, 7, 14 and 28 days ] [ Designated as safety issue: No ]

Enrollment: 5
Study Start Date: March 2006
Study Completion Date: April 2006
Primary Completion Date: April 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Experimental
All participants underwent the same dietary intervention
Other: Balanced macronutrient diet intervention
Isocaloric dietary changes from typically Western diet to balanced macronutrient composition.

Detailed Description:

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.
