About this trial

The overall objective of this multi-center study is to use metabolic response data from different dietary challenges to develop personalized dietary advice. Effectiveness of this personalized dietary advice compared to a general healthy diet based on national dietary guidelines on markers of cardio-metabolic health will be tested.

A total of 120 men and women who meet all inclusion criteria and none of the exclusion criteria will be invited to participate. The study will be conducted at three sites: Chalmers University of Technology (Sweden), University of Wageningen (Netherlands), and University of Oslo (Norway), with 40 participants per site.The study is conducted in two parts. The first part, the characterization phase, is a three-way randomized, controlled cross-over design, featuring one-day meal tests with isocaloric meals containing different carbohydrate, fat and protein quantity as well as quality. Based on the metabolic response to the meal tests a personalized diet will be constructed. In the second part, the main intervention, effectiveness of this personalized dietary advice compared to a general healthy diet will be tested in a six week parallel group intervention study.

Signed informed consent

Disqualifiers

History of diagnosed cardiovascular disease (e.g. stroke, heart disease)

Parallel

Treatments tested in this trial

  • General healthy diet

    Other intervention

    General healthy diet based on national health dietary guidelines.

  • Personalized diet

    Other intervention

    Personalized diet will be based on an algorithm considering the individuals' postprandial glucose, triglycerides and inflammation markers to each of the three study meals in the characterization phase (Phase I) matched with established knowledge about the effects of specific foods on such metabolic parameters.

2

Appetite

Differences in self-reported appetite measured using a visual analogue scale between test meals in the characterization phase of the study.

Time frame
6-hour meal test
3

Gut microbiome

Differences in fecal microbiome between test meals in the characterization phase of the study.

Time frame
6-hour meal test
4

Metabolome

Time frame
6-hour meal test

Other outcomes

1

Dietary biomarkers

Exploratory analysis of blood, urine and feces to find potential biomarkers reflecting dietary intake in the characterization and intervention phase of the study.

Time frame
6-hour meal test and 6 week intervention
2

Responsivness to diet

Exploration of underlying mechanisms behind response/non-response to personalized and general healthy diet using data from both the characterization phase (meal test) and the primary 6-week intervention.

Time frame
6-hour test meal and 6 week intervention
3

Gastric emptying

Gastric emptying will be assessed by breath test at one of the test meals in a sub-group of participants (Swedish and Norwegian site).

Time frame
6-hour test meal
4

Gastric passage time

Gastric passage time will be assessed using the blue dye method.

Time frame
6-hour meal test and 6 week intervention
