Food Reinforcement, Weight Status, and Energy Density

Completed

• Conditions: Reinforcing Value of Food
• Interventions: Behavioral: Daily snack food intake

• Registration Number: NCT03981172
• Lead Sponsor: State University of New York at Buffalo

Brief Summary

The investigators previous studies have shown that obese and non-obese individuals respond differently to daily intake of snack food. The purpose of this study was to determine whether these differences are specific to high energy density snack foods. The investigators hypothesized that obese individuals would show an increase in motivation to obtain high energy density snack foods after two weeks of daily consumption, but that non-obese women and obese women consuming low energy density foods would have reduced motivation to consume snack foods after two weeks of daily consumption.

Primary Outcome Measures

Name	Time	Method
Number of operant responses	about one month	Participants were asked to click a mouse button to gain access to food. A point was earned after a certain number of button presses and after 5 points were earned, the participant received 100 kcal portion of food.

Secondary Outcome Measures

Name	Time	Method
Food liking	about one month	participants rated how much they liked the food on a Likert-type scale.
