Study Summary
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).
Primary Outcome
A new method of digital photography of foods to measure the energy intake (EI) and macronutrient intake of free-living humans was tested. Digital photography (RFPM) EI was tested against measured food provisions during an in-feeding period and against EI measured with doubly labeled water (DLW) during free-living conditions for 1 week. EI measured by directly weighing food provisions in the clinic over two days and measuring food intake during free-living conditions over one week with the DLW.
Interventions

- OTHER doubly labeled water
