What role does tableware size play in energy consumption of children and adults?

In our recent article , we reported a novel analysis of the perceptions of tableware size in households of children and adolescents with obesity in comparison to participants with normal-weight matched for age and gender. At the time of the study, the influence of tableware on food intake was uncertain in adults and even more so in children, due to a lack of studies. Many articles in the field have been published by the group affiliated with Prof. Brian Wansink from Cornell University, which overall support the idea that larger package and/or dishware size leads to an increased intake of food portions. Brian Wansink resigned in 2018 after the university had found academic misconduct in several cases and more than 15 articles published in renowned and internationally peer-reviewed journals have been retracted since then.
In our manuscript, 10 of the 43 citations refer to the Wansink group, highlighting the influence of this group in the field. Two of the papers cited were retracted [
