A Pilot Study: Snacking, Willpower and Glucose Availability (SWG)

4. februar 2016 oppdatert av: University of Colorado, Denver
To compare the effects of ingesting 100, 50 and 10 calories of glucose as compared to a non-calorie placebo (0 calorie beverage) on self-control over resisting snack foods. To test whether there is a threshold of glucose that will result in improved ease of resistance to problem foods (tested by comparing three different levels of glucose).

Tiltaksbeskrivelse
Tidsramme
Responses to the Control of Eating Questionnaire
Tidsramme: 4 weeks

Study participant will complete Eating Questionnaire at baseline and the next 4 visits. Each questionnaire item used a likert scale (with ratings from 1 - 10). All question pertain to the last 7 days. Questionnaire items #9 asked "what one food makes it most difficult for you to control eating?" and question #10 asked " What time are you particularly vulnerable to this one food." Higher ratings are consistent with a more significant or more frequent outcome.

Note that values in the data table below are absolute scores at each week that the subject consumed the noted treatment dose. As subjects were randomized to different sequence orders to receive the study beverages, subjects consumed any given treatment dose at different weeks (depending on their randomized sequence order).

Tidsramme
Number of Days That a Problem Snack Food Was Consumed at the Identified Time of Waning Dietary Self-control.
Tidsramme: 4 weeks

Study participant will record if the problem snack was consumed each day within the 3 hour period following consumption of the study beverage.

Note that the values in the data table below reflect the percentage of days within a week that subjects within each treatment dose consumed a problem snack food at the identified time of waning dietary self-control. The data does not represent change from baseline, but rather percentage of days within a week (calculated by how many days within a week subject consumed the problem snack food at the identified time of waning dietary self-control/ 7 days in a week) and can be compared week by week to see if there is any significant difference weekly when consuming a different dose of glucose.

Number of Days That a Problem Snack Food Was Consumed at Any Time of Day in a Week.
Tidsramme: 4 weeks
Study participant will record daily the time problem snack food was consumed. Note that the values in the data table below reflect the percentage of days within a week that subjects within each treatment dose consumed a problem snack food at any time of day. The data does not represent change from baseline, but rather percentage of days within a week (calculated by how many days within a week subject consumed the problem snack food at any time of day/ 7 days in a week) and can be compared week by week to see if there is any significant difference weekly when consuming a different dose of glucose.
