#### *3.1. Recruitment, Drop-Outs and Baseline Characteristics*

From January to July 2020, *n* = 257 interested individuals registered for the clinical substudy (Figure 1). Registered individuals were contacted by phone and checked for inclusion and exclusion criteria. If these criteria were not violated, the individuals were invited to the baseline examination, where a final screening of the criteria took place. After these screenings, *n* = 153 individuals successfully completed the baseline examination. During the course of the study, *n* = 35 (22.9%) dropouts were observed. In both groups, dietary data were available for *n* = 52 subjects each across all measurement time points. These *n* = 104 subjects could therefore be included in the PP analysis of the dietary data. The baseline characteristics of participants in the two study groups were consistently similar and are shown in Table 1.
