Summary

The proposed clinical trial is a controlled study of n=24 healthy adult individuals tested in both the Meal-Induced Insulin Sensitization (MIS) state and, following atropine blockade, Absence of Meal-Induced Insulin Sensitization (AMIS) state to differentiate the postprandial glycemia, insulinemia, triglyceride and Hepatic Insulin Sensitizing Substance (HISS) levels in the two states. The purpose of this study is the identification and development of biometric markers which incorporate the actions and interplay between insulin and HISS. Overall, the study aims to: 1. Utilize a standardized test meal to detect one of the earliest pathologies present during the development of insulin resistance, pre-diabetes and obesity. 2. Compare the control (HISS positive) and post-atropine (HISS negative) tests with the acute consequences of absence of MIS (AMIS) being graphically shown over 4 hours of postprandial nutrient partitioning, tracking the full metabolomic dynamic pattern. 3. To establish values for potential indices (bio-impedance, hand-grip strength, spirometry) in young, fit, lean individuals. These values will be used as baselines for comparative analysis in future clinical trials employing individuals with various degrees of insulin resistance to full Type 2 Diabetes. 4. Demonstrate that these biometric markers can differentiate between the HISS positive and HISS negative post-meal state with the future aim of using the biomarkers for the detection of early prediabetes. The study will involve 4 study visits: Visit 1 - Prescreening; Visit 2 - Screening; Visit 3 - Liquid test meal administration and postprandial blood collection; Visit 4 - Atropine administration + Liquid test meal administration and postprandial blood collection.

Type	Name	Description
OTHER	Standardized liquid test meal	During this study visit, a standardized liquid test meal will be administered. Blood samples will be collected at baseline and then every 30 minutes for 4 hours after test meal.
DRUG	Atropine + Standardized liquid test meal	During this study visit, 1.0 mg atropine will be administered I.V and then a standardized liquid test meal will be administered. Blood samples will be collected at baseline, following atropine administration, and then every 30 minutes for 4 hours after test meal.
