• Effectiveness of individual pieces of personalized nutrition advice in the Food4Me study
  Food4Me has been one of the largest studies focusing on the effect of personalized nutrition (PN) advice on individuals' dietary behavior. It was shown that PN produced larger and more appropriate changes in dietary behavior than a conventional approach. The respective effect size, however, was quite small.
  Therefore, the aim of this project is to investigate the effectiveness of the individual pieces of PN advice given to the subjects and to identify those recommendations that produced the most substantial and appropriate changes in the subjects' dietary behavior.
   
• Non-compliance of controls in unblinded dietary intervention studies
  In intervention studies, blinding is the preferred way to ensure that members of control groups are not affected by the type of intervention. However, not every type of intervention can be blinded. Particularly, personalized nutrition studies cannot be conducted in a blinded manner, such that subjects are fully aware whether or not they come to enjoy the benefits of the intervention.
  Therefore, the aim of this project is to investigate the compliance of controls in unblinded dietary intervention studies, and to find out to which extend members of control groups seek to mimic the benefits offered to the intervention groups.
