Interaction Between White Potato Consumption and Meal Timing on Glycemic Response and Appetite 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.
