Trial Summary

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment ReeVue Indirect Calorimeter for weight loss in bariatric surgery candidates?

The ReeVue Indirect Calorimeter measures resting energy expenditure (REE), which is important for understanding energy balance and weight loss. Studies show that after bariatric surgery, there are changes in energy expenditure, which can help maintain weight loss. This suggests that using the ReeVue to monitor REE could support effective weight management in bariatric surgery patients.12345

Is metabolic rate testing using the ReeVue Indirect Calorimeter safe for humans?

The research articles provided do not contain specific safety data for the ReeVue Indirect Calorimeter or similar metabolic rate testing methods in humans.13467

How does metabolic rate testing differ from other treatments for weight loss in bariatric surgery candidates?

Metabolic rate testing is unique because it focuses on measuring and understanding the body's energy expenditure and metabolism, which can help tailor weight loss strategies more effectively for bariatric surgery candidates. Unlike other treatments that may focus solely on diet or surgery, this approach provides insights into how the body burns calories, potentially leading to more personalized and effective weight management plans.12368

What is the purpose of this trial?

This trial checks if knowing a person's resting calorie burn can help predict successful weight loss after surgery for weight loss and guide the choice of the best type of surgery.

Eligibility Criteria

This trial is for adults of any age who are scheduled to have their first bariatric surgery. It aims to include a broad range of participants without an upper age limit, focusing on those interested in understanding how their body's calorie burning at rest might influence weight loss after surgery.

Inclusion Criteria

I am scheduled for my first weight loss surgery.

Interventions

  • ReeVue Indirect Calorimeter
Trial Overview The study is testing the use of a ReeVue Indirect Calorimeter, which measures resting metabolic rate—the calories burned while the body is at rest—to see if this can predict successful weight loss following bariatric surgery.
