Participation in 150 min/wk of moderate or higher intensity physical activity yields greater weight loss after gastric bypass surgery.
This is a study from Virginia Commonwealth University and The Miriam Hospital in Rhode Island. This study compared the weight loss outcomes at 12 months from gastric bypass surgery in relation to a patient’s participation in 150 minutes or more per week of moderate to higher intensity exercise compared to those not meeting this requirement.
They followed several hundred patients at 3, 6 and 12 months after gastric bypass surgery. They found the patients that followed their recommendations of 150 minutes or more per week did significantly better in weight loss, %excess weight loss, total %weight loss and BMI reduction than other patients who did not comply with the exercise recommendations.
The reason for the better outcomes can be related to several reasons but some of the theories include improvement in Basal Metabolic Rate (BMR) and maintaining muscle mass. BMR is your ability to burn calories while you are at rest. When one decreases their caloric intake then the BMR decreases as well. We discuss this with each patient whether a patient has weight loss surgery or non-surgical weight loss. The study addresses gastric bypass patients but can be applied to Gastric Banding patients as well.
We encourage you to find an efficient way to get your exercise accomplished for the week. Call our exercise physiologist to set up an exercise assessment to help establish your 150 minutes of exercise per week. The exercise time is important but during that time you must be efficient that is being in the right range of intensity of the work out
