About this study

Giving personalised dietary advice will help mitigate the postprandial increases in TG and glucose levels, and will assist in the battle against the increase in nutrition-related diseases, such as cardiovascular diseases. Being able to predict postprandial responses, will be a first step to personalised dietary advice.

The primary objective of this study is to validate the prediction model on the effect of a standardized mixed meal challenge on postprandial TG levels in a heterogenous group of middle-aged, overweight to obese individuals. The secondary objectives are 1) to improve the accuracy of the predicted postprandial TG responses by increasing the number of postprandial TG measurements, 2) to determine which parameters can improve the accuracy of the predicted postprandial TG responses, 3) to determine if we can predict the effect of a standardized mixed meal challenge on postprandial glucose levels in a heterogenous group of middle-aged, overweight to obese individuals, and 4) to determine which parameters can improve the accuracy of the predicted postprandial glucose responses. Another objective is to validate dried blood spots postprandial triglyceride concentrations against venous blood concentrations.

There are minor risks for the research subjects of this study. Research subjects will invest approximately 13.5 hours in the study. They will visit the Wageningen University research facility three times and Hospital Gelderse Vallei once.

Read the detailed description

Elevated triglyceride (TG) and glucose levels are major risk factors for cardiovascular diseases. Therefore, mitigating the postprandial increase in TG and glucose levels may help curb a person's risk of developing cardiovascular diseases. Current strategies to stimulate people to adopt a healthy lifestyle, however, are still insufficient. This is partly due to the fact that nutritional advice is nowadays still given at the population level via general nutrition guidelines, while nutritionist have long been aware that what works for one person may not work for another. Giving personalised dietary advice will help mitigate the postprandial increases in TG and glucose levels, and will assist in the battle against the increase in nutrition-related diseases, such as cardiovascular diseases. Being able to predict postprandial responses, will be a first step to personalised dietary advice.

The primary objective of this study is to validate the prediction model on the effect of a standardized mixed meal challenge on postprandial TG levels in a heterogenous group of middle-aged, overweight to obese individuals. The secondary objectives are 1) to improve the accuracy of the predicted postprandial TG responses by increasing the number of postprandial TG measurements, 2) to determine which parameters can improve the accuracy of the predicted postprandial TG responses, 3) to determine if we can predict the effect of a standardized mixed meal challenge on postprandial glucose levels in a heterogenous group of middle-aged, overweight to obese individuals, and 4) to determine which parameters can improve the accuracy of the predicted postprandial glucose responses. Another objective is to validate dried blood spots postprandial triglyceride concentrations against venous blood concentrations.

Digital twin is an observational study with three visits, including one mixed meal challenge test day.

Study population consists of 38 volunteers, 45-75 year old, BMI between 25-35 kg/m2.

The primary study parameter is the postprandial triglyceride responses in blood upon a mixed meal challenge. The secondary study parameters are: postprandial responses in the blood upon a mixed meal challenge, and extensive phenotyping of the subjects by collecting data on fasting blood profiles of micronutrients, metabolites, and proteins, continuous blood glucose levels (Freestyle Libre), body fat composition (DEXA), liver fat percentage (MRI), habitual dietary intake (FFQ), and physical activity (ActivPAL3).

This study is related to a broad general population. There are minor risks for the research subjects of this study. Consumption of the liquid mixed meal may cause some gastro-intestinal discomfort. Blood sampling will be performed via a cannula and the insertion can be a bit painful and may cause a bruise. The amount of blood that is drawn from subjects is within acceptable limits (total amount collected = 186mL). The radiation dose received during the DEXA scan for measuring body composition, is negligible compared to the average dose each person in the Netherlands receives per year. Research subjects will invest approximately 13.5 hours in the study. They will visit the Wageningen University research facility three times: once for a short screening, once to collect phenotyping data, and once for a mixed-meal challenge test day. In addition, they will visit Hospital Gelderse Vallei once for an MRI measurement.

Questions about this trial

What is this clinical trial studying?

An observational study of Lipid Metabolism and Glucose Metabolism, run by Wageningen University and Research at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postprandial triglycerides blood levels (time frame: Baseline). The study lists 19 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jul 2022; AzTrials last refreshed its copy on 31 Oct 2026.
