- People who have a stoma (a surgically created opening from the bowel through the abdomen)

- People whose body mass index (BMI) is below 18.5 or above 35
- People who are not willing to follow the required food and lifestyle rules during the study

- People who are currently taking, or have taken in the past 3 months, antibiotics or probiotics, as these may affect gut function
