This study is simply to test the repeatability of the indirect calorimetry instrument the investigators use for our clinical studies.

Participants will be required to attend two study visits at the Arkansas Children's Nutrition Center. During the first visit, informed consent will be obtained, participant will be measured and an indirect calorimetry assessment to measure resting energy expenditure will be performed. During the second visit, we will repeat the indirect calorimetry assessment to measure resting energy expenditure.
