satiety quotient

The satiety quotient is calculated by dividing the difference between the subjective ratings of motivation to eat before and after a meal by the ingested energy intake during the eating episode. Introduced in 1997¹. Symbol, SQ.

“Evidence of the usefulness of both SI and SQ for quantifying satiety and their reproducibility are considered insufficient to be used for health claim substantiation.”²
