Factors Involved in Weight Loss Maintenance Post-Bariatric Surgery: A Test of Two Models


Approximately 20% of patients who undergo bariatric surgery (e.g., gastric banding) have poor weight loss outcomes. It is unclear why surgery results in substantial weight loss for most, but not all patients. Two separate models have recently been developed in an effort to conceptualise the psychological processes and factors thought to be involved in weight loss maintenance. Neither model has yet been tested in a bariatric surgery population. This project aims to test the validity of these models to determine their usefulness in explaining weight loss maintenance among bariatric surgical patients.

Why my research is important

Recent figures indicate that one-in-four Australian adults are obese. Effective treatments are required, as obesity is associated with significant health and psychosocial problems. Bariatric surgery is the only treatment to reliably show substantial and sustained weight loss in the majority of the morbidly obese. The impact of failing to achieve desired weight loss outcomes with surgical treatment can be devastating. A greater understanding of the psychological factors involved in outcomes is required to ensure the failure rate is minimised.
