Postprandial IHL and IMCL Measured With Proton Magnetic Resonance Spectroscopy

Not Applicable

Completed

• Conditions: Postprandial IHL and IMCL Dynamics
• Interventions: Dietary Supplement: High fat breakfast; Dietary Supplement: HF breakfast with protein

• Registration Number: NCT01709643
• Lead Sponsor: Maastricht University Medical Center

Brief Summary

The major research objective is to assess the potential of Proton Magnetic Resonance Spectroscopy to follow Intrahepatic lipid and Intramyocellular lipid dynamics after a single meal. Furthermore we aim to investigate whether the addition of protein to a high fat breakfast results in a reduced postprandial accumulation of lipids when compared to a high fat breakfast alone.

Detailed Description

Fat accumulation in non-adipose tissue, such as liver and muscle, is associated with reduced insulin sensitivity and cardiovascular disease. Little is known about the dietary determinants and the time course of this ectopic fat accumulation. Therefore the general aim of this project is to develop and validate methodology to follow postprandial hepatic and muscular lipid retention. Proton Magnetic Resonance Spectroscopy (1H-MRS) is a well-established tool for noninvasive quantification of intrahepatic lipids (IHL) and intramyocellular lipids (IMCL). Previous studies have suggested a relatively rapid regulation of IHL and IMCL levels, indicated by changes in these total lipid pools after high fat diets of 3 or 4 days. Although IHL and IMCL levels seem to change rapidly, data on IHL and IMCL levels after a single meal are lacking.

Arm && Interventions

Group	Intervention	Description
High fat breakfast lean subjects	High fat breakfast	Subjects will consume a high fat breakfast, containing of sausage rolls. Energy content of the breakfast will be set to 50 % of the recommended daily calorie intake (BMR times 1.3).

HF breakfast with protein,lean subjects	HF breakfast with protein	For the HFP breakfast, the subjects will consume 'Protifar' (Nutricia, Cuijk, The Netherlands) in addition to the sausage rolls. The amount of added proteins will be calculated to assure that the total energy content from proteins in the breakfast equals 20 %,

Primary Outcome Measures

Name	Time	Method
Difference between pre- and postprandial IHL and IMCL	3 and 5 hours after high fat breakfast	The primary research objective is to assess the potential of 1H-MRS to follow IHL and IMCL dynamics after a single meal in lean and obese subjects.

Secondary Outcome Measures

Name	Time	Method
Difference between postprandial IHL and IMCL in high fat and high fat with extra protein breakfast	3 and 5 hours after high fat breakfast	We aim to investigate whether the addition of protein to a high fat breakfast (HFP) results in a reduced postprandial accumulation of lipids when compared to a high fat breakfast (HF) alone.
