Weight loss maintenance can be a challenge regardless of the type of obesity treatment, and while metabolic/bariatric surgery (MBS) is the most effective treatment for weight loss, some patients may experience weight recurrence. This chapter will highlight evidence-based strategies for successful weight loss maintenance, including a focus on self-monitoring and physical activity, and the role of follow-up care for MBS patients. We will also discuss issues that may predispose patients to weight recurrence, such as maladaptive eating behaviors and psychosocial factors. Finally, we will review approaches to address factors impacting weight recurrence after MBS.
