title
Vette KIP: Exploration of new markers that define impaired metabolic flexibility using an acute postprandial challenge test
description
Response patterns of metabolic and inflammatory markers to a high-fat challenge (containing 80 g fat) were compared between 10 apparently healthy men and 10 men with characteristics of the metabolic syndrome (MetS) and in (the same) healthy men before and after a hig-fat high-caloric (HFHC, approximately 1300 kcal/day extra) diet for 4 weeks.

Human Intervention
Objectives
The primary objective of the study was to quantify specific metabolic processes in response to an acute oral fat load and compare these responses in apparently healthy subjects before and after four weeks consuming a high-fat high-caloric diet, between subjects with characteristics of the metabolc syndrome and apparently healthy subjects. Secondary objectives were to assess the reproducibility of responses to the acure oral fat load, and to explore how the colon microbiota is affected by a high-fat high-caloric diet and how changes in microbiota composition relate to baseline changes in inflammatory markers, change in baseline levels of glucose, insulin and blood lipids, and change in intestinal premeability.
