Resting Metabolic Rate Testing in Bariatric Surgery Patients

October 23, 2019


This study is evaluating if measuring the patient’s resting metabolic rate (the number of calories the body burns at rest) before bariatric surgery can help predict successful weight loss after surgery. Patients from the Baylor Weight Loss Surgery Center who have met all of the requirements for primary bariatric surgery will undergo pre- and post-operative metabolic testing using a calorimeter, and their weight loss results will be measured. The goal of the study is to attempt to accurately predict if surgery will result in successful weight loss and help to guide patients for the best type of surgery for them.
