Empowering Consumers to 'PREVENT' Diet-related Diseases Through 'OMICS' Sciences

The over-all aim of this 10-week randomized-controlled study, taking place only in Denmark, is to examine whether the PREVENTOMICS platform integrated in an e-commerce digital tool created to deliver personalized meals and dietary advices is able to produce more favorable health effects than meals based on general dietary recommendations in overweight subjects with elevated waist circumference.

PREVENTOMICs project (Empowering consumers to PREVENT diet-related diseases through OMICS sciences), coordinated by Eurecat (Spain), has developed a personalized nutrition platform with a Decision Support System (DSS) tool that integrates different disease-inducing metabolic signatures with genotype and other informative information such as the characteristics of individual's behavioural traits, to correlate health status and provide personalized nutritional plan.

To demonstrate the potential for personalization of the platform, PREVENTOMICS will be validated in three different scenarios through three different organizations carrying out intervention studies with both healthy volunteers and volunteers with abdominal obesity.

The current study in Denmark will be a 10-week double-blinded randomized (1:1 randomization), placebo-controlled trial carried out with overweight/obese subjects having elevated waist circumference living in Greater Copenhagen. After the confirmation of the inclusion criteria, 100 individuals will be randomly assigned to one of the two intervention groups. Both groups will receive meals from Simple Feast following the national guidelines of macronutrient composition. The control group (n=50) will receive meals based on general dietary recommendations whereas the meals of the second group (n=50) are personalized based on metabolic biomarkers (PP group). In addition, participants of both groups will receive electronic push notifications of behavioral change messages for the purpose of general behavioral change and improving adherence to the nutritional intervention, which will be sent during the 10-week trial by ONMI. However, subjects in the PP group will receive personally tailored and actionable behavior change prompts from the predefined ONMI's program while subjects in the control group will receive it in a non-personalized fashion with standard messages.

Our hypothesis is that delivery of personalized meal/plan through the PREVENTOMICS platform integrated with e-commerce digital tool, will promote a greater reduction in fat mass and weight, as well as producing favorable changes in blood metabolic and inflammatory biomarkers compared to the control group.
