^aEAH, eating in the absence of hunger.

^bLinear mixed models adjusted for condition, time, and condition*time. Unadjusted Models: separate models estimating relationships of EAH intake with PFS, mYFAS, and BIS. Interaction Model 1: model estimating the relationship of EAH intake with PFS, BIS, and the interaction of PFS with BIS. Interaction Model 2: models estimating the relationship of EAH intake with mYFAS, BIS, and the interaction of mYFAS with BIS.

^cEAH-kcal, energy consumed during EAH

^dEAH-%, percent of EAH food consumed (100[amount consumed (g)/amount served (g)])

^eIntake of all EAH test foods.

^fIntake of sweet EAH test foods (highly processed: cookies, peanut butter cups, brownies; minimally processed: grapes, apples, clementines)

^gIntake of savory EAH test foods (highly processed: potato chips, nacho chips, cheese popcorn; minimally processed: grape tomatoes, dry roasted unsalted peanuts, baby carrots)
