How to help Someone get their Appetite back?

Trying to increase the likelihood that someone will eat something?  Consider Zhou, Chen, and Li’s findings:  “Despite being a fundamental food feature, the effect of food shapes has been underexplored. This study demonstrates that giving hedonic [pleasure-related] foods a round shape increases their desirability, choice probability, and consumption. However, this effect does not apply to utilitarian foods. Such asymmetric effects are attributed to the positive affect [emotion] elicited by a round shape and not to the food’s shape typicality, food knowledge, vividness, or fragility. . . . the effectiveness of giving hedonic foods a round shape is attenuated [weakened] by consumers’ health motivations; that is, the effect holds only for those with low health motivation.”
