Effect of a High-Protein, High-Fiber Pre-Fast Meal on Satiety and Glycemic Profiles During Fasting
Recruiting now · Not applicable
Conditions studied: Glycemic Response; Satiety, Fasting, Time Restricted, Dietary Intervention, Postprandial Glucose
In brief
This randomized crossover study investigates the effect of consuming a high-protein, high-fiber pre-fast meal on subjective satiety and glycemic responses during fasting hours in healthy adults. Participants will complete two dietary conditions in a randomized order: a standardized high-protein, high-fiber pre-fast meal and a low-protein, low-fiber pre-fast meal guided by dietary instructions. Each condition will be followed for two consecutive days and separated by a three-day washout period. Outcomes include subjective appetite sensations during fasting hours, glycemic profiles assessed using continuous glucose monitoring (CGM), and exploratory analyses examining the association between glucose dynamics and appetite sensations.
