Summary

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.

Detailed description

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.

Conditions

• Healthy

Interventions

Type	Name	Description
OTHER	Dietary fat/intake of carbohydrate	Spontaneous intake of fat, carbohydrate, protein and alcohol each day for 17 days.
BEHAVIORAL	Spontaneous oscillations of dietary fat/intake of carbohydrate in relation to energy intake.	Dietitians and senior level or graduate level dietetics students who are not restrained eaters to participate in food intake over 17 days. During this same time interval, integrated energy expenditure will be recorded using doubly-labeled water and day to day energy expenditure by accelerometer. Periodic blood sampling for leptin will be done completed at site intervals.
