Summary

This study looked at whether measuring resting metabolic rate (how many calories your body burns at rest) before bariatric surgery can help predict weight loss after the procedure. Researchers planned to enroll 84 adults scheduled for primary bariatric surgery and use a device called the ReeVue Indirect Calorimeter to measure metabolism. The study was terminated early, so results are limited.
