Abstract
Purpose
Low-calorie (LCSs) may be negatively associated with weight and metabolic health. We hypothesized that LCS exposure may hinder the effectiveness of bariatric procedures. The aim of this study was to examine the association between preoperative LCS use and weight loss/comorbidity remission following sleeve gastrectomy and gastric bypass.
Material and Methods
We performed a retrospective chart review of 653 patients who underwent one of the two bariatric procedures and provided preoperative diet information. Patients who selected LCS as one of their most commonly consumed sweeteners and/or included “diet” drinks or sugar-free foods in their 24-h diet recall were categorized as “LCS users.” We used multiple logistic regression models to address the study objectives.
Results
Of 653 patients, 470 (72.0%) regularly consumed LCSs. LCS users were more likely to be older, have lower preoperative BMI, diabetic, using insulin, and have hyperlipidemia than non-LCS users. LCS consumption was not associated with the odds of achieving BMI < 35 kg/m2 nor the odds of achieving TBWL ≥ 20% in the adjusted models. While 39.6% of diabetic LCS users did not show remission, only 22.7% of diabetic non-LCS users did so at their last follow-up (p = 0.04). However, this association was attenuated when adjusted for insulin dependency.
Conclusions
There is no clear harm or benefit of preoperative consumption of LCS on weight loss or comorbidity remission after bariatric procedures. Further study is needed to more accurately assess the effect of LCSs on bariatric surgery outcomes.
