This randomized cross-over pilot clinical trial aims to evaluate the feasibility and effect of a relaxing virtual reality (VR) experience on glucose response after white bread consumption, compared to a stress-inducing VR, a VR clinical room, and a real clinical room, in healthy adults. Participants will use a head-mounted display to experience either one of the VR environments, or they will simply sit in an actual clinical room for 15 minutes. After this pre-meal condition, participants will consume 66 grams of white bread within 10 minutes, accompanied by 250 mL of water. They will then continue their assigned pre-meal condition for one hour, followed by an additional hour of sitting in the lab for further assessments. The feasibility of the study will be assessed by calculating: 1) Screening to randomization ratio, 2) Recruitment rate of participants per week, 3) Retention rate, 4) Data Completeness of Finger-Prick Glucose Measurements, and 5) VR intervention tolerability measured by Simulator Sickness Questionnaire (SSQ) score. Postprandial glucose response, stress levels, heart rate, and skin conductance will be assessed at baseline (15 minutes before white bread consumption), immediately before consumption (time 0), and at 15, 30, 45, 60, 90, and 120 minutes post-consumption. Palatability will be evaluated immediately after the meal consumption. Motivation to eat will also be assessed at 0, 15, 30, 45, 60, 90, and 120 minutes. Sense of presence will be measured immediately after VR exposure. Additionally, simulator sickness will be assessed at the beginning of the study and after VR exposure. The results will help us better understand the potential feasibility and benefits of using relaxing VR for postprandial glucose management. These findings will also provide evidence to optimize the design of future definitive randomized clinical trials and enhance the development of VR interventions.
