About the trial
What the trial wants to find out
In a crossover design, 8 participants will receive caloric drinks containing stable isotopes. In one arm of the study, participants will consume 6 hourly drinks containing two stable isotopes. Repeated blood, breath, urine, and muscle biopsies will be taken. In the second arm, participants will consume 1 drink containing 75g glucose, labeled with two stable isotopes of glucose. Periodic blood and breath will be taken over three hours.
The 2 groups in the trial
- IAAOTreatment being tested
Participants will ingest a series of 6 hourly beverages containing 50% of the daily intake of 1.1g/kg/day
Treatment: Indispensable Amino Acid Oxidation
- SIOGTTTreatment being tested
Participants will consume one 75g glucose drink dissolved in 250 ml of water.
Treatment: Stable Isotope Oral Glucose Tolerance Test
