Adherence
Laparoscopic Roux-en-Y Gastric Bypass (LGBP) induces a significant dietary shift towards lower fat intake and higher carbohydrate intake compared to Laparoscopic Vertical Banded Gastroplasty (LVBG), with approximately 30% of LGBP patients consciously avoiding fatty foods.
After LGBP surgery, patients naturally tend to reduce their fat intake, with about 30% consciously avoiding fatty foods due to post-meal discomfort. This behavioral shift contributes to the effectiveness of the surgery by reducing overall caloric density.
StrongSupportsHIGH confidence
LGBP patients decreased their proportion of dietary fat significantly more than those operated on with LVBG (P < 0.005)... almost one third of the LGBP patients consciously avoided fatty foods, mainly due to not feeling good after eating it
Why this rating
Randomized clinical trial with validated dietary questionnaires.

More from this paper
- Laparoscopic Roux-en-Y Gastric Bypass (LGBP) produces superior body composition outcomes compared to Laparoscopic Vertical Banded Gastroplasty (LVBG), specifically through greater reductions in total body fat, trunkal fat, and visceral adipose tissue, while better preserving lean tissue mass in men.Strong
- Postoperative Basic Metabolic Rate (BMR) decreases in proportion to weight loss after bariatric surgery, with no difference in BMR reduction between LGBP and LVBG, refuting the theory of postoperative hypermetabolism.Strong
