Trial of the health effects of personalised meal delivery in men and women with overweight and obesity

Research study in men and women with overweigh and obesity to assess the health effects of personalised meal delivery compared to meals following general nutritional recommendations.

personalised delivey meals

We plan to investigate whether personalised delivery meals and dietary advices are able to promote a greater reduction in excess body fat and weight, as well as producing favourable changes in overall health, compared to meals based on general dietary recommendations in men and women aged 18-65 years with excess body weight.

Volunteers will be allocated in one of two groups:

  • Personalised plan group: participants will receive meals prepared following their individualised needs based on an analysis of their metabolic biomarkers, preferences, health status, genetics and lifestyle habits. In addition, participants will be enrolled in a personalised behavioural change program via electronic push notifications.
  • Control group: volunteers will receive meals and dietary advices following general dietary recommendations. Participants will receive electronic behavioural prompts, but that will not be personalised.

This research study is being conducted at the Department of Nutrition, Exercise and Sports (NEXS) of the University of Copenhagen. It has been reviewed and approved by the Scientific Ethics Committee Region H in Denmark by journal number H-20029882.




We are looking for men and women aged 18 to 65 years old with a body mass index (in kg/m2) of ≥27.0 and <40.0, and elevated waist circumference (men >94.0 cm; women >80.0 cm).

Participants will have to attend one information meeting where they must provide informed consent, and three visit days at the Department of Exercise, Sports and Nutrition (NEXS), University of Copenhagen. Each visit consists of taking body measurements (e.g. height, weight, and body composition), blood, saliva, faecal and urine samples, as well as filling various questionnaires, for evaluating the physiological changes before and after the trial.

After the first visit day, data are analysed to develop the personalised diet plan and advices for the subsequent 10-week trial period.

Benefits for participants

During the study, that will last for 10 weeks, we will measure changes in body fatness, weight loss, waist circumference and changes in participants’ food intake, behaviour, physical activity and sleep, among other indicators, that tell us about the biochemical changes and processes in each volunteers’ body.

Participants will receive free breakfasts and dinners six days a week during ten weeks trial from Simple Feast. The meals will be vegetarian, but volunteers are allowed to eat non-vegetarian foods in the meals that are not delivered. Recipes for other meals will be provided through the Simple Feast App, matching the nutritional recommendations to be followed by each participant.

In addition, participants can benefit from a behavioural change program delivered through mobile app push notifications.

By participating in this study, volunteers may benefit from losing weight, reduce excess body fat and waist circumference, whilst improving their overall health.

Obesity, a multifactorial global epidemic

Obesity results from environmental, physiological, social and genetic factors. Over the last three decades, worldwide obesity rates have increased dramatically with more than 30% of world’s population being overweight or obese. It is associated with increasing rates of diabetes, hypercholesterolaemia, non-alcoholic fatty liver disease and hypertension, which are risk factors for the development of cardiovascular diseases.
