In the past decade there has been an increase in obese and obesity rate in the Netherlands. To address this issue, it is important to look at one of the reasons why the effort of dieting might not be effective. This paper discovered that one reason that leads to ineffective dieting is underreporting of dietary intake. Underreporting of dietary intake may occur when participants does not disclose their food consumption honestly when reporting their dietary intake in a journal or diet tracking apps. Since this information is private information, finding subjective truth is often difficult. In this paper, I tried to use the Bayesian Truth Serum method to test if this questioning method can significantly reduce truth telling when it comes to disclosing dietary intake and food habits. The Bayesian Truth Serum method has been proven in a theoretical setting to induced truth telling by incentivizing participants to tell the truth. After conducing and analyzing the survey done, I found out that the Bayesian Truth Serum method does not significantly outperformed the normal dietary intake assessment method when it comes to reducing dietary underreporting.
