Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of the research is to determine energy expenditure rates and diet and/ physical activity metabolic features of an individual using current state technologies and a new technology created at the Center for Bioelectronics and Biosensors at ASU. This is a pilot study which intent is to validate this device for use in the weight loss patient population. This study will involve research of metabolic physiological parameters that are measured through the breath of the individuals, together with other physical parameters (weight, height, date of birth, fat and lean body composition via bio-impedance, heart rate, blood pressure, and breathing rate) assessed in the clinic, and a questionnaire about diary physical activities. The study will involve withdrawn of breath samples at resting conditions, and under diets or physical activities regimes. This instrument will assist our patients in terms of tailoring their diet/nutrition through their weight loss journey prior and after surgery. As a new technology, it will be an excellent tool for compliance assessment and engagement with the Weight Loss Program as well as for long term follow up.
