ListOutcomeTime frameDescriptionSource
PrimarySubjective reward responses to food intake (in lab)10 minutes before intake of test snack, during, and 30-, 60-, 90-, and 120 minutes after intake of the test snack.
Indicators of subjective reward (craving, palatability, hedonic hunger, and mood) will be assessed by participants' self-reports before, during, and after consumption of the test snack at each of the four food consumption appointments. Each facet of subjective reward will be assessed by 100-point visual analog scales ranging from 0-100.
ClinicalTrials.gov
PrimarySubjective reward responses to food intake (EMA)EMA surveys administered over 5 days following each food consumption assessment (20 total days of EMA data)
Indicators of subjective reward (craving, palatability, hedonic hunger, and mood) will be assessed by participants' self-reports in EMA surveys. Each facet of subjective reward will be assessed by 100-point visual analog scales ranging from 0-100.
ClinicalTrials.gov
PrimaryAd libitum consumption2 hours after test snack intake at each food consumption assessment.
Total number of calories consumed from the test snack food during a 15-minute eating period. Calories will calculated by measuring bowls containing the test snacks before and after participant consumption on a digital scale accurate to 0.01 grams. The difference in grams will be converted into the calories that the participant ate.
ClinicalTrials.gov
PrimaryDaily calorie intake (EMA)EMA surveys administered over 5 days following each food consumption assessment (20 total days of EMA data)Calorie intake will be derived from participants' self-reported food consumption in EMA surveys.ClinicalTrials.gov
PrimaryConsumption of UPFs and MPFs (EMA)EMA surveys administered over 5 days following each food consumption assessment (20 total days of EMA data)
Trained study staff will calculate the percentage of participants' daily calories from the four food categories (UPF+FRC, UPF+F, UPF+RC, MPF) based on participants' self-reported food consumption in EMA surveys.

SecondaryChanges in heart rate in response to food intake10 minutes before intake of test snack, during, and 30-, 60-, 90-, and 120 minutes after intake of the test snack.Manually measured by counting the radial pulse for 15 seconds (timed using a digital stopwatch).ClinicalTrials.gov
SecondarySalivation responses to food intake10 minutes before intake of test snack, during, and 30-, 60-, 90-, and 120 minutes after intake of the test snack.Participants will spit into a plastic cup for 1 minute and the weight of their saliva will be measured in grams using a digital food scale accurate to 0.01 grams.ClinicalTrials.gov
SecondaryMagnitude of metabolic responses to food intake10 minutes before intake of test snack, during, and 30-, 60-, 90-, and 120 minutes after intake of the test snack.Serial blood draws will be conducted before, during, and after test snack consumption. Samples will be assayed for glucose, insulin, ghrelin, and leptin levels.ClinicalTrials.gov
OtherIndividual risk factors for enhanced ultra-processed food rewardTasks administered at baseline assessment (prior to any food consumption appointments) or follow-up assessment (at least one week or up to 2 months after the last food consumption appointment)
Characteristics known to increase one's reward responsiveness to substances like alcohol will be assessed by behavioral tasks and evaluated as predictors of ultra-processed food reward (delay discounting task to assess impulsivity; Stroop task to assess cognitive functioning; relative reinforcing value task to assess reward value of various foods).
