Study start date: July 31, 2017

Actual date on which the first participant was enrolled.

This is a prospective study enrolling patients from the Baylor Weight Loss Surgery Center who have met all of the requirements to proceed with primary bariatric surgery. Patients will undergo pre-operative and post-operative metabolic testing (6 months, and 1 year after surgery) using a portable calorimeter with eventual follow up of medical record at 5 years. Data from up to 50 patients will be collected. The main objectives are to examine if the pre-operative resting metabolic rate can accurately predict successful weight loss after bariatric surgery and if it can be used to guide the selection of the type of bariatric surgery that would be most successful for the patient.
