Assessment of Energy Balance (EnergyBalanc)

May 28, 2017 updated by: Corby K. Martin, Pennington Biomedical Research Center
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).

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will take place over a period of one year. Participants will spend 3 weeks completing Phase I, and eight weeks completing Phase II (the weight loss phase of the study). Then, participants will return to the center at months 6 and 12 for a follow-up visit. During these visits, body weight, blood pressure, and pulse will be recorded, and questionnaires about eating attitudes and habits will be collected and assessed.

Experimental: Sub-study 1, Dig Photo, Actical & IDEEA
During one week of the doubly labeled water (DLW), participants will use digital photography of foods. During the other week of the DLW phase, participants will wear the Intelligent Device for Energy Expenditure and Activity (IDEEA) monitor and Actical monitor. Whether the participants wear the monitors first or complete digital photography first will be randomozed. Participants who complete the first two weeks and have a BMI over 25kg/m2 will receive a partial supplement low-calorie diet (LCD) for 8 weeks. This diet plan is a 1000-1150 kcal/day diet that participants will complete in a free-living environment. All participants will return to follow-up at six and twelve months after they completed the LCD. Anthropometric and questionnaire data will be collected.
Behavioral: Digital Photography of Foods
The digital photography of foods method was developed to unobtrusively measure energy intake in naturalistic settings (e.g., cafeterias). Participants will be provided with cell-phones with digital cameras and cellular network capability. Participants were trained to take pictures of their food selection and plate waste and to send these pictures to the researchers over the cellular network. The participant will collect data in free-living conditions and these data will be collected in near real time.
Other Names:
  • digital photography
Other: doubly labeled water
Doubly labeled water, considered the gold standard for measuring energy intake in humans, was used to measure total daily energy expenditure during free-living conditions. DLW is used to obtain an accurate measure of total daily energy expenditure, which is equal to energy intake during energy balance.
Other Names:
  • Doubly labeled water (DLW)
Device: IDEEA
The Intelligent Device for Energy Expenditure and Activity (IDEEA) will be used to measure the time spent engaging in active vs. sedentary behaviors, and the energy costs of these behaviors.
Other Names:
  • Intelligent Device for Energy Expenditure and Activity
Behavioral: low-calorie diet
Participants will be instructed to consume five packets of Health One per day, which provides 800 kcal and 125% of Recommended Daily Intake of vitamins and minerals. Additionally participants will be instructed to consume a meal consisting of 200 kcal to 350 kcal daily, which could consist of a portion-controlled meal replacement or a home-cooked meal. Participants will meet with a Registered Dietitian at weeks 0, 2, 4, and 6 and receive instructions on adhering to the meal plan.
Other Names:
  • LCD
Device: Actical
The Actical will be used to measure the time spent engaging in active vs. sedentary behaviors, and the energy costs of these behaviors.
Experimental: Sub-study 2 - Dig Photo & Sensewear
During one week of the doubly labeled water (DLW) period, participants will use digital photography of foods. During the other week of the DLW phase, participants will wear the Sensewear armband. Whether the participants wear the monitor first or complete digital photography first will be randomozed. Participants who complete the first two weeks and have a BMI over 25kg/m2 will receive a partial supplement low-calorie diet (LCD) for 8 weeks. This diet plan is a 1000-1150 kcal/day diet that participants will complete in a free-living environment. All participants will return to follow-up at six and twelve months after they completed the LCD. Anthropometric and questionnaire data will be collected.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
ENERGY BALANCE EQUATION, PHASE I, ONE SUB-STUDY
Time Frame: ~6 days
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.
~6 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Weight Change
Time Frame: 1 year
The secondary aim was to test if posture allocation (the amount of time spent engaging in certain behaviors e.g., sitting, walking, running, changing positions and the energy burned during these activities) predicts weight change over one year following a period of weight loss.
1 year
Total Energy Expenditure (TEE) and Activity Energy Expenditure (AEE) Predictions From Actical, IDEEA, and Sensewear Monitors (kcal/Day)
Time Frame: 1 week
Bland-Altman analyses compared the TDEE and AEE from the Sensewear® and IDEEA and Actical monitors to the DLW data from the week participants wore the monitors. Only the week of DLW data that corresponded with the wearing of the monitors was used for this analysis.
1 week
Device Predictions of % Weight Change During and After an 8-week LCD
Time Frame: 8 weeks
This secondary aim of the study was evaluated with linear regression analysis to determine if TEE, AEE, or measures of posture allocation predicted weight loss during the 8-week LCD. Percent weight change from diet initiation to termination was the dependent variable for the weight loss regressions. Of the 87 participants considered for these secondary analyses, five were excluded because they did not finish baseline accelerometry assessment, and an additional five were excluded because they did not enter the LCD phase due to BMI's < 25. Finally, seven more participants from this original sample were excluded because they did not successfully complete all aspects of the DLW dosing period. Finally, an additional 4 subjects were lost to follow up during the 8-week LCD period. Thus, 66 participants were included in the analysis
