Summary

The researchers are investigating the satiety effects of two commercially available snack bars. Qualified participants are age 18-65 with a body mass index of 18.5 to 29.9 kilograms of body weight per meter squared in height who are in good metabolic health. Participants will engage in two study visits conducted at the Indiana University--Bloomington Innovation Center.

Study visits are separated by a 1-14 day washout period. Prior to each study visit, participants are asked to engage in normal activity and to refrain from strenuous exercise. Furthermore, subjects are asked to consume a typical diet the day prior to the study visit with one caveat; they are to consume standard frozen dinners (evening meal) of their choosing between 7-8 PM and to remain fasted afterward except for water and non-caloric beverages until the study visit the following day. The amount of food provided for the evening meal is estimated using a standard calorie calculator based on the Mifflin-St. Jeor equation and an estimate of their activity level. Subjects are instructed to consume only as much of the provided food as needed to become comfortably full as they would ordinarily. Subjects record their diet for the day.

Upon arrival at the Innovation Center between 8-8:40 AM, compliance with the prior day protocol is verified through interview, and the diet record is reviewed. Participants consume 300 kcal of snack bars and complete visual analogue scales to assess hunger, fullness, desire to eat, and satisfaction at fasting and at 30 minute intervals from the fasting measurement for 2 hours. Immediately after consuming the snack bars, subjects complete a sensory evaluation of the snack bars. Fifteen to thirty minutes after completion of the final visual analogue scale, subjects will be presented with an individual buffet which they consume ad libitum until comfortably full.

A second study visit that mirrors the first but with different bars is conducted after the washout period (1-14 days).
