“…Considerable improvement of all lipid sub-fractions was observed during follow-up in our study, in line with other investigations[20,25,26]. The Swedish obese subject (SOS) study indicated that the incidence rate of hypertriglyceridemia was significantly lower in the surgically treated group than in the control group after two years[27].…”

AIMTo investigate changes in adiposity and cardio-metabolic risk profile following Roux-en-Y gastric bypass in patients of Middle Eastern ethnicity with severe obesity.METHODSThis prospective cohort study involved 92 patients who met the indications of bariatric surgery. Post-procedure markers of obesity and cardiometabolic profile were monitored regularly for a year.RESULTSMean body mass index decreased by 29.5% from 41.9 to 29.5 kg/m2 between baseline and 12-mo follow-up, while mean fat mass decreased by 45.9% from 64.2 kg to 34.7 kg. An improvement was also observed in the gluco-metabolic profile with both fasting glucose and HbA1c substantially decreasing (P < 0.001).CONCLUSIONThe present study shows the short to medium term (1 year) health benefits of bariatric surgery for patients of Middle Eastern ethnicity.

“…It could also be useful to assess impulsivity pre-operatively, though Sheets and colleagues [25] argue that especially post-operative variables seem to have an impact on weight loss outcome after bariatric surgery. Brandão and colleagues [27] hypothesized that impulsivity might be more associated with weight regain after surgery and not with weight loss. Thus, several post-operative measurement points concerning weight regain and weight loss outcomes should be completed.…”

“…However, some researchers [12,27] did not find a predictive value of impulsivity on EWL after bariatric surgery. Thus, Gerlach and colleagues [12] propose that pathological eating behavior might mediate the association between impulsivity and weight loss outcome.…”

The Impact of Impulsivity on Weight Loss Four Years after Bariatric Surgery

et al. 2016

Bariatric surgery has serious implications on metabolic health. The reasons for a failure of bariatric surgery, i.e., limited weight loss, are multifactorial and include psychological factors. We established a theoretical model of how impulsivity is related to weight loss outcome. We propose that depressive symptoms act as a mediator between impulsivity and pathological eating behavior, and that pathological eating behavior has a direct impact on weight loss outcome. We calculated excessive weight loss (%EWL) and assessed self-reported impulsivity (using the Baratt Impulsiveness Scale (BIS-15) total score), depressive symptoms (the Patient Health Questionnaire (PHQ-9) score), and pathological eating behavior (the Eating Disorder Inventory 2 (EDI-2) total score) in 65 patients four years after laparoscopic sleeve gastrectomy. Regression and mediation analyses were computed to validate the theoretical model. The BIS-15, PHQ-9, and EDI-2 have medium to high correlations between each other, and EDI-2 correlated with %EWL. The mediation analysis yielded that the PHQ-9 represents a significant mediator between BIS-15 and EDI-2. The regression model between EDI-2 and %EWL was also significant. These results support our theoretical model, i.e., suggest that impulsivity has an indirect impact on weight loss outcome after bariatric surgery, mediated by depression and transferred through pathological eating behavior. Thus, the underlying psychological factors should be addressed in post-operative care to optimize weight loss outcome.

“…Eating behaviors is referred to as one of the components of weight management. In fact, psychological variables were reported to be associated with weight loss [7,8] . Clinical studies are limited using objective scores of eating behavior in association with weight management.…”

The aim of this study was to test the association of eating behavior with weight loss and weight regain after dietary intervention in obese females. Twenty-nine obese females were included in this study. Eating behavior using the Three-Factor Eating Questionnaire (TFEQ), which measures uncontrolled eating, emotional eating, and cognitive restraint eating, was tested for its association with weight loss (baseline to 3 months) and weight regain (3 to 15 months). Uncontrolled and emotional eating at the baseline was associated with weight regain, although cognitive restraint eating was associated with weight loss. Information on eating behavior may help to identify people who require additional support to maintain a reduced body weight after dietary intervention in obese females.
