Are All Snacks Created Equal?

Clinicaltrials.gov identifier NCT03940105

Study Description

Brief summary:

The investigators propose a randomized snack study in normal to obese adults that will test whether snack size, choice, or variety has an influence on daily snack intake. Aim 1: To validate the in-house packout methodology with 3-day dietary recalls. Aim 2: To examine whether snack variety or snack package size will influence free-living snacking behavior. Aim 3: To identify whether a correlation exists between mindful eating and free-living snacking behavior.

  • Condition or Disease:Snacking
  • Intervention/Treatment: Behavioral: Packout
  • Phase: N/A
Detailed Description

Participants will complete 4 different snack patterns. Each pattern will include 3 nonconsecutive weekdays (i.e., Monday/Wednesday/Friday; Tuesday/Thursday/Monday, etc.). The snack patterns will be performed at home/work. The first pattern will simply be a measurement of typical snack habits. For each of the 3 days, the participant will enter all foods and beverages consumed using the online program, Automated Self-Administered 24-Hour Dietary Assessment Tool (ASA-24). For the other 3 patterns, different snack packouts will be provided to the participant for 3 nonconsecutive weekdays/pattern. The only difference between the packouts is the type of foods provided. The packouts contain commercially available foods commonly eaten by people who snack. Following lunch, the participant will be permitted to eat as much or as little as he/she chooses from the packout until going to bed. Beverages will not be provided and the participant could drink whatever he/she typically consumes. For all patterns, the participant will be provided with a standardized breakfast, lunch, and dinner to consume at home/work for each of the 3 days/pattern.

Arms and interventions
Arm Intervention/treatment
Active Comparator: Large Package Packout
This packout contains a variety of foods to be consumed, ad libitum, throughout the remainder of the day following the standardized lunch. It differs from the Standard Packout in that the package sizes of all the foods are larger (though food amount remains the same).
Behavioral: Packout
Each packout provided during 3 of the 4 snack patterns will contain a variety of foods to be consumed, ad libitum, throughout the remainder of the day following the standardized lunch. There are 3 different packouts that will be provided for 3 nonconsecutive weekdays (for a total of 9 packouts). Each packout contains the same calories and types of foods. However, they differ in packaging size and variety.
Active Comparator: Standard Packout
This packout contains a variety of foods to be consumed, ad libitum, throughout the remainder of the day following the standardized lunch.
Behavioral: Packout
Each packout provided during 3 of the 4 snack patterns will contain a variety of foods to be consumed, ad libitum, throughout the remainder of the day following the standardized lunch. There are 3 different packouts that will be provided for 3 nonconsecutive weekdays (for a total of 9 packouts). Each packout contains the same calories and types of foods. However, they differ in packaging size and variety.
Active Comparator: Variety Packout
This packout contains a variety of foods to be consumed, ad libitum, throughout the remainder of the day following the standardized lunch. It differs from the Standard Packout in that there is about twice as much snack variety (though food amount remains the same).
Behavioral: Packout
Each packout provided during 3 of the 4 snack patterns will contain a variety of foods to be consumed, ad libitum, throughout the remainder of the day following the standardized lunch. There are 3 different packouts that will be provided for 3 nonconsecutive weekdays (for a total of 9 packouts). Each packout contains the same calories and types of foods. However, they differ in packaging size and variety.
Outcome Measures
  • Primary Outcome Measures: 1. Ad libitum Snack Energy Intake [ Time Frame: 12 testing days across ~4-6 weeks ]
    Free-living energy intake will be assessed on the three testing days of each testing arm. For the control testing days, the participant will be provided with a standardized breakfast, lunch, and dinner, and will be required to log any snacks consumed on the Automated Self-Administered Recall System (ASA24). For each pack-out testing day, the participant will be provided a standardized breakfast, lunch, and dinner, as well as an excess of snacks to consume, ad libitum, throughout the day. All food items will be initially weighed and recorded. The participants will be instructed to return all uneaten foods as well as all wrappers and containers from consumed food. Any partially eaten, returned items will be weighed accordingly. The snacking and daily energy intake (as well as protein, carbohydrate, sugar, fiber, and fat intake) will be assessed from these pack-outs.
  • 2. Ad libitum Food Category Intake [ Time Frame: 9 testing days across ~3-5 weeks ]
    Free-living food category intake will be assessed on the three testing days of each packout. The participant will be provided a standardized breakfast, lunch, and dinner, as well as an excess of snacks to consume, ad libitum, throughout the day. All food items will be initially weighed and recorded. The participants will be instructed to return all uneaten foods as well as all wrappers and containers from consumed food. Any partially eaten, returned items will be weighed accordingly. The snack intake of different food categories (i.e. desserts and candy, salty, high fat, high sugar, fruits and vegetables) will be assessed from these pack-outs.
  • 3. Intuitive Eating Score [ Time Frame: Baseline (at beginning of study) ]
    Participant will complete Intuitive Eating Scale-2 survey in order to receive an Intuitive Eating Score.
