All about the study

We are looking for healthy adults who are willing to:

1. Take part in a 5-week trial that will involve a 4-week intervention period (whereby the study will provide all the meals you will be consuming for six days a week).
2. Provide blood, urine, and stool samples on two occasions.
3. Have an ultra-sound of the artery in your arm on two occasions.

You may be eligible if you can answer “yes” to the following statements:

• I am aged 30-70y
• I am willing to take part in a 5-week trial and follow the meal plan provided for 4 weeks
• I am willing to answer questionnaires about my physical and mental health

What does the study involve?

If you take part, we will ask you to consume three daily meals, as well as snacks, that we will provide to you for 4 weeks. These meals are designed to help us understand how diet may support gut and cardiometabolic health. You will be able to consume your own food and meals one day a week.

We will ask you to provide stool samples to assess the bacteria living in your gut, and also urine (24h collection) and blood samples to assess key compounds (metabolites) that may be influenced by diet and mediate potential benefits of the study diets. We will also assess your cardiovascular health by taking an ultrasound of your artery in your arm. We will also ask you to fill out questionnaires on your bowel habits, gut symptoms, and mental health, and keep a food diary throughout the study.

Overall, you will attend three in-person study visits at King’s College London, Waterloo, SE1 9NH.

Benefits of taking part

• You will be compensated £100 for completion of the study.
• You will receive free frozen meals and snacks for 4 weeks.
