Brief summary
Bowel cleansing prior to colonoscopy is crucial to be able to perform a high-quality examination. Therefore maximum efforts are made to achieve optimal bowel cleansing including diet restriction and refraining from day-before dinner. However, the effect of this interdiction is currently not clear. On the other hand, patient compliance and experience with the entire procedure is important, especially for follow-up colonoscopies. Strict diets may interfere with this as an additional burden on the patient. In this study we want to assess whether a more lenient diet influences the quality of bowel preparation and whether it improves patient's experience.
Interventions
The interventional goup receives the lenient diet instructions and will eat a light meal until 18h on the day before the colonoscopy. The first dose of Plenvu will be started at 20h. All the other bowel preparation instructions will be the same as in the control group.

Masking description
The endoscopist who performs the colonoscopy and the investigator who acts as second observer are blinded to objectively assess the BBPS.
