Study Summary

The changing food environment, with increasingly abundant ultra-processed food (UPF) options, may directly contribute to rising rates of obesity, though it is unknown which ingredients in UPF elevate their reinforcing nature in a way that may lead to overconsumption. The proposed study is the first to systematically examine differences in the rewarding characteristics of and physiological and metabolic responses to UPFs that are high in fat, refined carbohydrates (like sugar), or both. Understanding the biobehavioral underpinnings that enhance the reinforcing potential of ingredients in UPF (e.g., fat vs. refined carbohydrates) can inform novel intervention targets for the treatment of overeating and obesity.

Primary Outcome

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.
