Background Avocados are a rich source of fiber and monounsaturated, which are nutritional factors linked to enhanced satiety. The benefit of consuming avocados at a meal on post‐meal satiety is unknown. Aim and Methods A randomized 3×3 single‐blind crossover design (three 1‐day study periods scheduled 1 week apart) in 26 healthy overweight adults (16 women,10 men; mean±SD age 40.8±11.0 years; BMI 28.1±2.4 kg/m 2 ) was conducted. Subjects consumed a standardized breakfast meal containing 25% of their daily energy needs on each of the 3 days, followed by 1 of 3 lunch meals [Control, avocado‐free (35% of daily energy needs); isocaloric Avocado Inclusive (AI; 35% of daily energy needs); and, Avocado Added (AA; 41% of daily energy needs). Visual analog scales (VAS) were administered 30, 60, 120, 180 and 300 minutes after the start of the lunch meal to assess subjective feelings related to satiety. The area under the curve (AUC; %*min) was evaluated using the trapezoidal method (mixed model included treatment and phase as fixed effects and subjects nested within sequence as random effects). Results There was no significant difference between the 3 treatments in the AUC for the self‐reported subjective feelings related to satiety (P = 0.19–0.87). Conclusion The inclusion or addition of avocado to a lunch meal does not influence self‐reported subjective feelings related to satiety over a 5 hour post‐meal period. Funded by the Hass Avocado Board
