Abstract: Background: Australians' demand for metabolic and bariatric surgery is increasing, yet research on when fat-free mass, weight, and resting metabolic rate stabilise post-procedure is contradictory. Aim: To explore and describe the changes in calculated resting metabolic rate, fat-free mass, and total body weight in patients undergoing metabolic and bariatric surgery over 12-months post-procedure. Methods: A single-site longitudinal observation study recruited metabolic and bariatric surgery patients from a private clinic between June 2020 and January 2024. Anthropometric measures and body composition (dual energy x-ray absorptiometry) were taken pre-procedure, 6-months, and 12-months post-procedure. Resting metabolic rate was calculated using the Mifflin St. Jeor equation with fat-free mass. Data were analysed in SPSS and paired t-tests were performed between time points. Results: N = 30 participants (BMI: 41.1 ± 8.0 kg/m2, age 48.5 ± 9.6 years, 93% female) were assessed pre- and 6-months post procedure, n = 22 had additional 12-month measures. Weight changes had not stabilised by 12-months post-procedure (0–6 months: 26.26 ± 9.05 kg, p < 0.001, 6–12 months 5.59 ± 4.77 kg, p < 0.001). Fat-free mass and calculated resting metabolic rate had stabilised by 6-months (5.87 ± 3.47 kg, p < 0.001; 484.0 ± 286.0 kJ/day, p < 0.001), with no significant changes from 6 to 12 months. Conclusion: In metabolic and bariatric surgery patients, decreases in fat-free mass and calculated resting metabolic rate stabilised by 6-months; however, weight loss continued to 12-months suggesting weight loss between 6- and 12-months is driven by a loss of fat-mass. Future research with shorter follow-up as well as the use of indirect calorimetry may enhance results. Longer-term follow-up may help in long-term management of weight and body composition.

Authors: Chronic pelvic pain is a debilitating condition affecting up to 25% of women and people assigned female at birth. Despite evidence supporting the role of nutrition in pain management, there has been limited exploration of nutrition and food related behaviours for those who live with chronic pelvic pain.
