Assessment of Energy Balance

Completed · Not applicable

Conditions studied: Caloric Intake and Energy Metabolism

In brief

The primary purpose of this study is to test different methods of measuring energy balance, including food intake and energy expenditure. Another primary purpose of this study is to see if energy expenditure predicts weight and change after a weight loss diet. A secondary aim will be to test the reliability and validity of the Actical accelerometer, SenseWear Armbands, and the Intelligent Device for Energy Expenditure and Activity (IDEAA) monitors at measuring activity energy expenditure (AEE) and total daily energy expenditure (TEE) against the gold standard, doubly-labeled water (DLW). Similarly, we will test whether the estimated energy expenditure or posture allocation from the 3 devices is associated with weight change during and following a low calorie diet (LCD).

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 18-65 years
• Body Mass Index 25-40
• Willing to eat foods provided for two days.
• Willing to wear the IDEEA( Intelligent Device for Energy Expenditure and Activity), which is a device that attaches to the body and records movement and activity.
• Willing to wear an accelerometer, which is similar to a pager that attaches to belt or clothing and measures activity.
• Willing to use a cell phone equipped with a digital camera to take pictures of foods for one week.
• Willing to undergo an 8 week weight loss diet, consisting of supplement or powdered shakes, portion-controlled entrees, or home-cooked meals.

You may not qualify if…

• A diagnosis of diabetes, cardiovascular disease, or cancer.
• Females who are pregnant or planning to become pregnant during the trail.
• Medications that influence appetite or body weight (weight loss medications such as sibutramine, antipsychotic medications such as olanzapine, or herbal weight loss products) taken during the previous three months.
