Design outcomes

Primary

Measure	Time frame
The data of the patients (weight development, laboratory measures, intake of supplements etc.) will be collected in a data file and will be analyzed after 5 years. If current recommendations (as for the intake of vitamins and minerals) are not sufficient, the recommendations will be adapted and improved and will be directly considered during the consultations with the patients.
