Resumen breve

The purpose of this study is to examine the effects of a low calorie high fat/protein diet on body fat and body composition in overweight and obese subjects. The investigators will also test the effects of this diet on secondary outcomes such as: fluid and electrolyte balance, cholesterol, inflammation, sugar and insulin metabolism, fat hormones, blood pressure and feelings of fullness.

Descripción detallada

Participation in this study requires 2 screening visits to the outpatient clinic, and if participants qualify, 10 inpatient study weeks.

Subjects will be admitted to the Rockefeller University Hospital for the 10 week in-patient phase of the study. The first 2 weeks consist of a weight stabilization period, during which subjects will be required to eat an average American diet. This is followed by the 6 week weight loss period where subjects will be put on a low calorie high fat/protein diet. During the weight loss period, calories will be cut by 50% compared to the weight stabilization period. This will be followed by a 2 week weight maintenance period during which calories will be added to the diet to maintain the new weight. Appropriate adjustments will be made to keep the subject's weight stable.

During the entire inpatient study, subjects will consume one multivitamin per day (Centrum, always complete, from A to Zinc) and one iron supplement per day. In addition, unlimited access to zero calorie liquids (water/diet soda) will be available and subjects will be encouraged to maintain their usual activity level.

Females of reproductive age need to make sure that they do not become pregnant during the inpatient study. Urine will be tested for pregnancy once during each phase of the study.
