研究概览
简要总结
The purpose of this study is to understand the mechanisms for oscillations of dietary fat/carbohydrate intake and how fat intake affect insulin resistance and liver fat over interval of 3 to 4 days.
详细描述
You will be expected to keep diet records for 17 consecutive days. You will start with a fasting screening visit (only water allowed). A physical exam and Medical history it taken at screening visit. Your body composition will be gathered by CT and Dexa Scan. Blood and urine will be collected for a chemical profile and other determinations. Questionnaires will be administered along with an accelerometer to be worn for the remainder of the study. The final day you will return the dietary records, accelerometer, and a few procedures will be performed as weight.
