This is a randomized controlled trial examining the effect of a motivational interview and perioperative mobile-app based nutrition and exercise intervention on surgical outcomes. The hypothesis is that such an intervention will improve surgical outcomes. Patients who are planned to undergo major elective abdominal surgery will be randomized to standard care or the nutrition/exercise intervention. This intervention consists of a mobile-app based coaching program to encourage patients to exercise and adopt a Mediterranean diet in the 3+ weeks prior to surgery.
