Carbohydrate Intolerance

Brief summary

The purpose of this study is to evaluate the validity of using a carbohydrate intolerance questionnaire (CIQ) and/or other health markers as a means of predicting response to insulin sensitivity as determined by an oral glucose tolerance test (OGTT).

Detailed description

This study will utilize a carbohydrate intolerance questionnaire (CIQ). Responses to a CIQ will be correlated with diet inventories, baseline body composition and health assessments, a standard metabolic panel, fasting glucose and insulin levels, a homeostatic insulin resistance model (HOMA), a two hour oral glucose tolerance test (OGTT), and a carbohydrate sensitivity symptom questionnaire administered during the OGTT.
