An interventional study of Control snack and Maltodextrin snack in Satiety and Food Intake, sponsored by Toronto Metropolitan University. Completed at 1 site in Canada. Open to participants aged 18 Years to 30 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-07-05.

The purpose of this study was to determine the effect of mid-morning gel snacks on subjective appetite, glucose and insulin responses, and food intake in healthy weight young adults.
23 (14 male, 9 female) healthy, non-smoking human subjects aged 18-30 years with a body mass index (BMI) between 20 and 24.9 were recruited in the experiment. Five gel snacks including a control snack and four modified snacks containing whey protein, oats, coconut oil or maltodextrin were tested. On six separate mornings, at least 3 days apart and after a 12 hours overnight fast, each participant consumed a standardized breakfast of cereal, milk, and orange juice at home, then arrived in the lab 2 hours after breakfast to receive one of the five test snack treatments or skip snack. Subjective appetite by a 100 mm visual analogue scale (VAS) was measured at baseline (0 min) and after each treatment up to 2 h (15, 30, 60, 90, and 120 min). Blood glucose and insulin concentrations were measured via finger-prick at the same time VAS measurements were taken. Food intake was measured via ad libitum pizza lunch.

Subjective Appetite
Participants completed subjective ratings on appetite (e.g., desire to eat, hunger, fullness, prospective food consumption) and well-being at baseline (0 min), 15, 30, 45, 60, 90, and 120 min after snack consumption, as well as immediately following lunch.

Blood Glucose Response
Blood was collected at baseline (0min), 15, 30, 45, 60, 90, and 120 min after snack consumption, as well as immediately following lunch to observe glycemic responses to gel snacks
Time frame: Change from baseline over 120 minutes
Blood Insulin Response
Blood was collected at baseline (0 min), 15, 30, 45, 60, 90, and 120 min after meal consumption, as well as immediately following lunch, to observe insulin responses to gel snacks
Time frame: Change from baseline over 120 minutes
Food Intake
Participants consumed an ad libitum pizza lunch at 120 minutes
