What is the term for measuring the amount of food that remains uneaten on a plate?

Measuring the amount of food that remains uneaten on a plate is referred to as plate waste. This term specifically indicates the quantity of food that is not consumed and left over after a meal, and it serves as an important metric for evaluating food acceptance, portion size, and overall satisfaction in various settings, including restaurants and dietary studies. Understanding plate waste helps dietitians and foodservice managers improve menu planning, reduce food waste, and meet nutritional needs more effectively by adjusting portion sizes and food offerings based on consumers’ preferences.

The other terms provided, such as satisfaction surveys, focus on gathering feedback regarding the overall dining experience rather than specifically measuring uneaten food. Frequencies of acceptance might refer to how often certain foods are accepted or liked but do not capture the amount of food wasted. Average check typically refers to the average amount spent by customers and is unrelated to food waste measurement.
