Intervence / Léčba
Detailní popis
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.

Intervence / Léčba |
|---|---|
|
Experimentální: Lycium Barbarum mixed meal
Subjects will receive a high-fat mixed meal containing Lycium Barbarum once.
|
This mixed meal contains 25 grams of dried Lycium Barbarum (Goji berry, Wolfberry)
|
|
Aktivní komparátor: Control mixed meal
Subjects will receive a high-fat mixed meal without Lycium Barbarum as a control.
|
This mixed meal does not contain Lycium Barbarum, but is matched for energy and macronutrient content

Co je měření studie?
Primární výstupní opatření
Měření výsledku |
Popis opatření |
Časové okno |
|---|---|---|
|
Change from baseline energy expenditure
Časové okno: Measured as the incremental area under the curve (iAUC) from 0 minutes to 140 minutes after meal intake
|
Energy expenditure will be measured using indirect calorimetry (ventilated hood system).
This system measures oxygen consumption (VO2) and carbon dioxide production (VCO2) to calculate the energy expenditure (kJ/min)
|
Measured as the incremental area under the curve (iAUC) from 0 minutes to 140 minutes after meal intake

|
Change from baseline energy expenditure
Časové okno: Measured as the incremental area under the curve (iAUC) from 160 minutes to 200 minutes and from 220 minutes to 260 minutes after meal intake
|
Energy expenditure will be measured using indirect calorimetry (ventilated hood system).
This system measures VO2 and VCO2 to calculate the energy expenditure (kJ/min).
|
Measured as the incremental area under the curve (iAUC) from 160 minutes to 200 minutes and from 220 minutes to 260 minutes after meal intake
|
|
Postprandial lipid and glucose oxidation
Časové okno: At baseline (T0, fasting) and between 0 minutes and 140 minutes, between 160 minutes and 200 minutes and between 220 minutes and 260 minutes after meal consumption
|
Lipid and glucose oxidation will be calculated from indirect calorimetry data (VO2 and VCO2).
|
At baseline (T0, fasting) and between 0 minutes and 140 minutes, between 160 minutes and 200 minutes and between 220 minutes and 260 minutes after meal consumption
|
|
Metabolic flexibility
Časové okno: At 60, 120, 180 and 240 minutes after meal intake
|
Metabolic flexibility will be derived from indirect calorimetry as the difference in respiratory quotient (RQ) between fasting and postprandial conditions.
|
At 60, 120, 180 and 240 minutes after meal intake
|
|
Markers for lipid metabolism
Časové okno: At baseline (T0) and at regular intervals up to 240 minutes after meal consumption
|
Several markers for lipid metabolism will be measured in blood samples.
|
At baseline (T0) and at regular intervals up to 240 minutes after meal consumption
|
|
Markers for glucose metabolism
Časové okno: At baseline (T0) and at regular intervals up to 240 minutes after meal consumption
|
Several markers for glucose metabolism will be measured in blood samples.
|
At baseline (T0) and at regular intervals up to 240 minutes after meal consumption
|
|
Inflammatory status
Časové okno: At baseline (T0) and at 60, 120, 180 and 240 minutes after meal consumption
|
Several markers for inflammatory status will be measured in blood samples and in vitro conditions
|
At baseline (T0) and at 60, 120, 180 and 240 minutes after meal consumption
