They were asked to report how much they like M&M® candies and Lays ® plain potato chips on a 7-point Likert scale. Participants had to report liking at least one food >5 on this scale and the highest rated food was chosen for use in the study. If a participant did not meet eligibility requirements,
they were told “Because this is a research study, we need to control for a variety of factors, such as age, medical history, or food liking or allergies. Unfortunately, you are not eligible due to one of these factors.
