Abstract

In Brief Objective: To assess body composition, eating pattern, and basal metabolic rate in patients undergoing obesity surgery in a randomized trial. Introduction: There is limited knowledge regarding how different bariatric surgical techniques function in terms of altering body composition, dietary intake, and basic metabolic rate. Methods: Non-superobese patients were randomized to laparoscopic Roux-en-Y gastric bypass (LGBP, n = 37) or laparoscopic vertical banded gastroplasty (LVBG, n = 46). Anthropometry, dual-energy x-ray absorptiometry (DEXA), computed tomography (CT), indirect calorimetry, and reported dietary intake were registered prior to and 1 year after surgery. Results: Follow-up rate was 97.6%. LGBP patients had significantly greater reduction of waist circumference and sagittal diameter compared with LVBG. DEXA demonstrated a larger reduction of body fat in all compartments after LGBP, especially at the trunk (P<0.001). CT demonstrated more reduction of the visceral fat (P=0.016). Patients were able to eat all types of food after LGBP, although about 30% claimed they avoided fats. LGBP patients decreased their proportion of dietary fat significantly more than those operated on with LVBG (P = 0.005), who consumed more sweet foods and avoided whole meat and vegetables. Lean tissue mass (LTM) was proportionally less reduced, especially in men, after LGBP. The decreases in BMR postoperatively reflected the lower body mass in a pattern that did not differ among the groups. Conclusion: LGBP patients demonstrated better outcomes compared with LVBG patients in terms of body composition. Energy expenditure developed as expected postoperatively. A “steering” away from fatty foods after LGBP may be an important mechanism of action in gastric bypass. Non-superobese patients were operated with laparoscopic gastric bypass or laparoscopic vertical banded gastroplasty in a randomized clinical trial. The outcome 1 year after surgery concerning anthropometry favored gastric bypass with a body composition reflecting a lower metabolic risk. No differences were found concerning the development of basic metabolic rate, while there were large differences in eating patterns where patients after gastric bypass “normalized” their diet and reduced their intake of calories, especially from fat foods.

  • RYGB subjects typically lose more weight and more bone at the hip and femoral neck at one year than those who undergo gastric banding or vertical banded gastroplasty.

    “Typically, RYGB subjects lose more weight and more bone at the hip and FN at one year than those who undergo GB44, 52 or VBG.72.”

  • Endorsements of favorite foods were mostly sweet/fatty foods in subjects awaiting surgery but shifted toward more healthy choices, particularly vegetables, in subjects post-RYGB.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
