Determinants of Total Body Weight Loss Among Palestinian Adults Post–Bariatric Surgery

Abstract

This study aimed to determine total weight loss percent (%TWL) and the contributing factors in 100 patients post-bariatric surgery. Self-reported anthropometric measurement, 13 dietary behaviors, lifestyle, sociodemographic, and bariatric surgery–related data were collected from the participants via telephone. The results revealed a %TWL mean of 29.00% ± 10.30%. %TWL was significantly associated with exercise, preoperative body mass index, locality type, and intake of dairy products (P < .05). Significant positive changes in dietary behaviors were reported postsurgically (P < .001). This study highlights the role of exercise and diet as part of overall post–bariatric surgical care.
