Objectives:
The primary objective of this study is to investigate the effect of a single dose of L. Barbarum on postprandial energy expenditure. Secondary objectives are to investigate the effect of a single dose of L. Barbarum on postprandial lipid and carbohydrate oxidation and metabolic flexibility, on postprandial lipid and glucose metabolism and on inflammatory markers.
Study design:
This is a double blind, randomized, placebo-controlled intervention trial with two test days separated by a washout period of at least 1 week.
Study population:
The study population will consist of 20 apparently healthy overweight (BMI between 25 and 30 kg/m2) men aged 18-65 years.
Intervention:
All subjects will receive a mixed meal including 25 grams of dried L. Barbarum as the intervention product and a matched mixed meal without L. Barbarum as the placebo product. The meals will be matched for energy content and macronutrient composition.
