Self-reported taste changes and food/physical activity preferences correlate with successful weight loss in females who underwent bariatric surgery

Abstract Background Bariatric surgery is the most effective treatment for obesity. During long-term follow-up, weight loss (WL) is variable between subjects. The aim of this study is to assess the change in percentage of total weight loss (%TWL) and excess weight loss (%EWL) and to describe the factors associated with greater or lesser WL over time. Methods Longitudinal study including patients treated with laparoscopic Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (LSG) and followed at Hospital Universitario San Ignacio, Bogotá (Colombia). Baseline data was recorded before surgery. Follow-up was performed at 3 (n=192), 6 (n=190), 9 (n=188), 12 (n=186), 24 (n=99) and 36 (n=30) months. Generalized Estimating Equation (GEE) analysis was used to assess the change in %TWL and %EWL over time. Results 196 patients were included (82.4% female, BMI 41.3±5.2 kg/m2). The tendency to increase on %TWL (31.6±6.6) and %EWL (80.2 RIQ 70.7-97.3) was evident in the first year, stabilizing after that. Nutritionist follow-up, baseline BMI>40 kg/m2 and WL≥10kg before surgery were associated with an average higher increase of %TWL (2.39% p=0.014, 0.41% p<0.001 and 0.37% p=0.003, respectively). Subjects who performed physical activity >30 minutes/day after surgery reduced %TWL in 0.74% (p=0.009). Similar findings were described on %EWL. Conclusion Follow-up during the first year after bariatric surgery is critical to achieving %TWL and %EWL goals. This study suggests that modifiable factors such as nutritional follow-up, WL before surgery and time of physical activity are associated with a significant change in %TWL and %EWL during follow-up by a multidisciplinary team.

Functional Capacities

IntroductionBariatric surgery leads to loss of fat and fat-free mass (FFM). To preserve FFM it is recommended that weight loss interventions are accompanied by physical activity. However, it remains unknown if functional capacities spontaneously improve after a substantial weight loss. Study’s aim was to assess the effect of bariatric surgery on strength, functional capacities and quality of life of participants with a body mass index (BMI) ≥ 35 kg/m2.MethodAnthropometric parameters (weight, BMI, waist circumference), physical functions (quadriceps strength, walking capacity, spatio-temporal gait parameters, dynamic balance, lower limb power) and quality of life were assessed before and at three months after the bariatric surgery in 33 individuals who did not follow any physical activity program.ResultsThe anthropometric parameters, quality of life and three functional abilities (walking capacity, normal gait speed and lower limb power) improved significantly three months post-surgery. In contrast, fast gait speed, absolute strength, normalized strength, and dynamic balance did not improve.DiscussionA massive weight loss should be accompanied by an exercise program aiming to maintain FFM and to enhance muscle strength and balance. Such a program might also enhance functional capacities and help to sustain the weight loss over time.

Definition Of

Bariatric surgery is the most effective therapy for morbid obesity. Unfortunately, a significant number of patients experience significant postoperative weight regain, which undermines the metabolic and cardiovascular benefits of weight loss associated with surgery. When revisional procedures are not indicated and/or when behavioral factors are present (e.g., nonadherence, eating pathology), bariatric programs currently do not have any empirically evaluated treatment options to offer those burdened with less favorable outcomes. This chapter reviews the definition of successful weight loss after bariatric surgery, as well as some biologic and behavioral factors that could be implicated in weight regain after surgery. Finally, we outline the scientific evidence supporting the use of behavioral and medical therapies to prevent weight regain after surgery. Bariatric programs need to determine from clinical experience, as well as through clinical trials, what behavioral/medical therapies are the most effective for managing weight gain after bariatric surgery.
