The Morning Coffee Study

November 23, 2023 updated by: Amanda Wright, Ph.D., University of Guelph
The liking of a breakfast meal has been shown to influence food choice throughout the day. This study will investigate the effects that liking of different coffee beverages has on daily food intake.

Study Overview

Detailed Description

This is a postprandial acute meal crossover blinded study in which 30 fasted young healthy women will consume one of 3 butter-rich coffees, in random order, at each of three study sessions separated by at least 4 days. Participants will rate the coffee characteristics and complete paper visual analogue scale ratings of alertness, fatigue, nausea, satiety, and comfort for 180 minutes and consume a pasta lunch meal. A subset of 10 participants will be invited to attend 3 additional study visits where gastric emptying following consumption of each coffee will be assess using gastric ultrasound.
