Effects of meal order on exercise and glucose metabolism
The Effect of Ordered Eating on Postprandial Glucose and Substrate Utilization During an Acute Exercise Bout
This study tests whether the order in which you eat carbs before or after exercise affects how your body handles glucose and how well you perform during workouts.

What this trial studies
This study investigates how the order of carbohydrate-rich foods in a meal affects glucose metabolism and exercise responses. Participants will experience two different meal conditions: consuming carbohydrates first or last. The goal is to understand how these meal sequences influence post-exercise glucose levels and overall metabolic responses. The study focuses on physically active individuals who can perform moderate-to-high intensity running.
Who should consider this trial
Good fit: Ideal candidates are physically active individuals who exercise regularly and can perform moderate-to-high intensity running.
Not a fit: Patients with conditions that prevent them from exercising or those with dietary restrictions related to the study foods may not benefit.
Why it matters
Potential benefit: If successful, this study could provide insights into dietary strategies that improve glucose control and exercise performance for individuals at risk of type 2 diabetes.
How similar studies have performed: While there is existing research on meal composition and glucose responses, this specific approach of manipulating meal order in relation to exercise is relatively novel.
