Overview

This randomized crossover study aims to investigate the effect of circadian timing of a standardized meal (morning versus evening consumption) on postprandial glucose response in healthy adults. Postprandial glucose will be assessed using the incremental area under the curve (iAUC) over 120 minutes.

Interventions

  • Other Standardized Test Meal
    The standardized test meal provided 50 g of carbohydrates of weighed portions of white bread and jam, served with 200 mL of water.

Primary outcome measures

  • Incremental Area Under the Curve (iAUC) for Postprandial Glucose [Time frame: Baseline to 120 minutes after consumption of the standardized test meal]
Secondary outcome measures (3)
  • Peak Postprandial Glucose (Morning vs Evening) [Time frame: Baseline to 120 minutes after consumption of the standardized test meal]
  • Time to Peak Glucose (Morning vs Evening) [Time frame: Baseline to 120 minutes after consumption of the standardized test meal]
  • Postprandial Glucose Profile (Morning vs Evening) [Time frame: Baseline, 15, 30, 60, 90, and 120 minutes after consumption of the standardized test meal]
