Which term refers to an overindulgence that leads to satiety or disgust?

The term that refers to an overindulgence that leads to satiety or disgust is "surfeit." This word specifically describes a situation where there is an excessive amount of something, particularly food or drink, resulting in an overwhelming feeling and often leading to adverse reactions, such as nausea or a strong aversion.

Surfeit captures the idea of going beyond what is necessary or healthy, conveying the notion that while indulgence may initially be pleasurable, it can ultimately result in negative feelings due to excess. This concept contrasts with the other terms presented. For example, "deficit" implies a lack or shortfall rather than an abundance, and "scrutiny" relates to careful examination or inspection, which does not connect to the idea of indulgence. "Moderation," on the other hand, represents the concept of balance and restraint—essentially the opposite of overindulgence that leads to satiety or disgust. Thus, "surfeit" is the most suitable term for describing excessive indulgence with negative outcomes.
