Examining the Efficacy of a Commercially Available Multi-ingredient Liquid Tonic Drink on Postprandial Glycemia in Men and Women With Overweight and/or Obesity.
Examining the Efficacy of a Commercially Available Multi-ingredient Liquid Tonic Drink on Postprandial Glycemia in Men and Women With Overweight and/or Obesity.
A randomised, double blinded, placebo-controlled crossover design clinical trial conducted at the Mary MacKillop Institute for Health Research (MMIHR, Australian Catholic University) for individuals with overweight/ obesity. This study will measure the postprandial glucose and hormone responses to a high-carbohydrate meal with/ without a liquid tonic drink.
Twenty individuals living with overweight/ obesity will be invited to attend the university laboratories on 2 separate occasions to participate in a postprandial (meal) challenge. Participants will consume the same high-carbohydrate meal on each visit, with or without a liquid tonic drink. This will be a cross-over design study, where participants will consume a placebo drink on the alternate visit. Participants will remain in the laboratory for 3-hours following the meal with a venous cannula in place, and have blood samples taken at regular timepoints. Blood samples will be analysed for glucose and appetite hormones. Participants will also wear a continuous glucose monitor throughout the period which encapsulates both study trials.
