“…Long-term data on diet or physical activity after surgery were not available, and the male sample size was smaller than the female sample size (mostly in the LRYGB group), reflecting that fewer men than women choose bariatric surgery [1,7]. In this regard, Kennedy-Dalby et al [21] observed that the global frequency of bariatric surgery is significantly lower in men than in women, despite the high prevalence of morbid obesity. It is unclear whether this is due to the perception of poorer outcomes in men.…”

“…4 The majority of individuals who use weight loss programmes, including bariatric surgery, are women. 5,6 Investigating whether outcomes differ between men and women is import in developing gender-specific treatment programmes, if required. [6][7][8][9][10][11][12] Differences in outcome after weight loss have been reported previously, with men commonly losing more body weight and fat than women.…”

AimsThe PREVIEW lifestyle intervention study (http://clinicaltrials.gov Identifier: NCT01777893) is, to date, the largest, multinational study concerning prevention of type‐2 diabetes. We hypothesized that the initial, fixed low‐energy diet (LED) would induce different metabolic outcomes in men vs women.Materials and methodsAll participants followed a LED (3.4 MJ/810 kcal/daily) for 8 weeks (Cambridge Weight Plan). Participants were recruited from 8 sites in Europe, Australia and New Zealand. Those eligible for inclusion were overweight (BMI ≥ 25 kg/m2) individuals with pre‐diabetes according to ADA‐criteria. Outcomes of interest included changes in insulin resistance, fat mass (FM), fat‐free mass (FFM) and metabolic syndrome Z‐score.ResultsIn total, 2224 individuals (1504 women, 720 men) attended the baseline visit and 2020 (90.8%) completed the follow‐up visit. Following the LED, weight loss was 16% greater in men than in women (11.8% vs 10.3%, respectively) but improvements in insulin resistance were similar. HOMA‐IR decreased by 1.50 ± 0.15 in men and by 1.35 ± 0.15 in women (ns). After adjusting for differences in weight loss, men had larger reductions in metabolic syndrome Z‐score, C‐peptide, FM and heart rate, while women had larger reductions in HDL cholesterol, FFM, hip circumference and pulse pressure. Following the LED, 35% of participants of both genders had reverted to normo‐glycaemia.ConclusionsAn 8‐week LED induced different effects in women than in men. These findings are clinically important and suggest gender‐specific changes after weight loss. It is important to investigate whether the greater decreases in FFM, hip circumference and HDL cholesterol in women after rapid weight loss compromise weight loss maintenance and future cardiovascular health.

“…Previous studies have described conflicting results regarding whether women lose more weight than men [2, 10]. As partners in 34 of 35 couples reported the same residential address and likely had similar support networks associated with being married, our study offered a unique opportunity to assess weight loss by gender.…”

There exists marked variation in weight loss among the 200,000 annual bariatric patients, and many of these patients struggle with weight regain. Several studies have suggested that positive social support may significantly impact bariatric surgery outcomes, leading to more excess weight loss and maintenance of this weight loss through appropriate lifestyle changes. We sought to understand this by assessing clinical and behavioral outcomes among married couples whereby both spouses underwent bariatric surgery at our institution. In our case series, we found evidence that married couples meet or exceed postoperative weight loss milestones at 12, 18, and 24 months and did not show signs of weight regain as a group at 18 or 24 months. Among partners who underwent the same clinical pathway at our single institution, women tended to lose more weight than men at 12 months. Additionally, while there was significant variation in postoperative follow-up among patients, we found that partners within couples typically exhibited the same behavior with respect to postoperative visits when they had their surgeries within a year of each other. This case series suggests that partnered patients undergoing bariatric surgery can meet or exceed weight loss outcomes and may practice similar follow-up adherence.
