Brief description of study
What is this study being done?
We want to know if snack bars that differ in their nutritional content also differ in how they affect how full you feel and how much food you eat in your next meal. Also, we would like to find out if your feelings about food and the way you eat affect your feelings of fullness and how much you eat in a meal a few hours after consuming the snack bars.
Who can take part?
Adults ages 18-65, in overall good health, who are are willing to attend study visits and pick up study food at Indiana University School of Public Health in Bloomington, IN.
Detailed description of study
What will happen during the study?
- You will complete a screening visit to see if you qualify (1-1.5 hrs).
- If you are eligible and choose to participate, you will be randomly assigned, like the flip of a coin, to the order that you will consume each snack bar.
- You will be asked to attend two study visits (approx. 3-3.5 hrs each).
Study tasks will include the following:
Complete questionnaires: You will be asked to complete a couple of questionnaires about how and what you eat. We will also figure out how much food you should typically eat in a day using an online app from the National Institutes of Health (NIH Body Weight Planner).
Pickup study food: You will be asked to come to the IU School of Public Health during business hours (9 AM to 5 PM) the day prior to the study visit to pick up your dinner.
Schedule study visit: We will schedule two days that are not more than 10 days apart for you to come to the IU Innovation Centre in Bloomington, IN for your study visit. The schedule can be coordinated according to your schedule and the Innovation Centre's schedule. We may need upto 2 weeks advanced notice to buy and prepare your food.
Eat assigned meals: The dinners provided by the study will need to be consumed between 7 and 8 PM each time (twice). You will need to have access to a refrigerator to store your food and a microwave or some other way to heat up your dinner.
Track your diet: On each of the days before you come to the Innovation Centre for your study visits, you will track your diet on a nutrition app for the day before each of two study visits and to consume a dinner that we have made for you between 7 and 8 PM the night before the study visit.
We will not conduct study visits or ask you to track your diet on weekends.
