Interaction Between White Potato Consumption and Meal Timing on Glycemic Response, Subjective Appetite, and Energy Intake in Adults.
Interaction Between White Potato Consumption and Meal Timing on Glycemic Response, Subjective Appetite, and Energy Intake in Adults.
The purpose of this study is to evaluate the interaction between white potato consumption and meal timing on glycemic response, subjective appetite, and energy intake in adults. The investigators hypothesize that white potatoes will modulate glycemic response, enhance satiety, and mitigate subsequent meal consumption and overall food intake when compared with meals containing low glycemic carbohydrates. Furthermore, they anticipate that the timing of white potato consumption will yield differential effects, with breakfast consumption exerting a more pronounced impact on satiety and subsequent food intake reduction compared to dinner consumption.
A randomized within-subject repeated measures experiment will be used to study the interaction between white potato consumption and meal timing on glycemic response, subjective appetite, and energy intake in adults. In Experiment 1, participants will consume, in a random order on separate mornings, one of six test meals consisting of an egg omelette and a test side of: (1) Oven-baked home fries, (2) Oven-baked white russet potatoes, (3) Deep-fried, quick serve fries, (4) Oven-baked fries, (5) Oven-baked cauliflower tots, or (6) no side. Acute glycemic response and subjective appetite will be measured at baseline and over 120-mins post treatment consumption. At 120-min, food intake will be evaluated via an ad libitum lunch. Rest of day food intake and glycemic response will be collected until the participant goes to bed. Blood glucose measurements will be collected using the Dexcom G7 continuous glucose monitoring system.
