“…Consistent with other studies, our results reflect significant improvements in the anthropometric variables in obese patients after LSG [5][6][7][8][9][10][11][12]. Moreover, our study confirms that LSG induced a substantial improvement in several glucose parameters.…”

In this study, we investigated the relationships between body weight (BW), computed tomography (CT)-assessed abdominal adipose tissue, and the glycemic metabolic profile in obese Japanese patients following laparoscopic sleeve gastrectomy (LSG). This study analyzed adipose tissue compartments using CT methods before and 1 year after LSG. Thirty obese patients were studied, and variables measured included visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), density of VAT (VAT-D), and density of SAT (SAT-D). We also examined the parameters in patients according to whether they had type-2 diabetes (T2DM). LSG induced significant losses in BW, SAT, and VAT after LSG. Additionally, SAT-D and VAT-D both increased and fasting plasma glucose (FPG) and HbA1c, but not C-peptide, decreased after surgery. ΔSAT and ΔVAT were positively related, and ΔSAT-D and ΔVAT-D were negatively related to ΔBW and/or FPG. Furthermore, a multivariate regression model showed that total BW loss (TBWL) was closely related to ΔSAT (β = 0.84; p < 0.001) and ΔVAT-D (β =-0.45; p < 0.05) and improvement of FPG was related to ΔVAT (β = 0.61; p < 0.05) after LSG. Finally, ΔFPG was correlated with ΔVAT in 16 T2DM patients (r = 0.58; p < 0.05) but not in non-T2DM patients. TBWL was related to ΔSAT and ΔVAT-D, and improvement of FPG was related to ΔVAT in obese Japanese patients after LSG.

“…However, its effects are limited in time, and weight regain is a common complication in bariatric patients, mainly after restrictive procedures. In the literature, a dramatic increase in %EWL in the first months after surgery as well as a reduction of the FFM have been described 17 . Afterwards, weight loss slows down, until a point of maximum weight loss is reached between 12 and 24 months after surgery 3,5 .…”

Weight regain is one of the most common problems in the long-term after bariatric surgery. It is unknown if high-intensity exercise programs applied in late phases of post-surgical follow-up could counteract this trend. After a 3-year follow-up, 21 patients underwent sleeve gastrectomy were randomized into an exercise group (EG, n = 11), that performed a 5-month supervised exercise program, and a control group (CG, n = 10), that followed the usual care. Body composition, cardiorespiratory fitness, glycaemia and blood cholesterol were evaluated before and after the intervention. Finally, the EG repeated the evaluations 2 months after the end of the exercise program. Both groups reached their maximum weight loss at the first year after surgery and showed significant weight regain by the end of the follow-up. After the exercise program, the EG showed reductions in fat mass (−2.5 ± 2.6 kg, P < 0.05), glycaemia (−13.4 ± 8.7 mg•dL −1, P < 0.01) and blood cholesterol (−24.6 ± 29.1 mg•dL −1 , P < 0.05), whereas the CG during the same period showed increases in weight (1.5 ± 1.3 kg, P < 0.05) and fat mass (1.8 ± 0.9, P < 0.01). Two months after the end of the program, EG had increases in weight (1.1 ± 1.2 kg, P < 0.05), fat mass (2.6 ± 2.2 kg, P < 0.01), glycaemia (8.2 ± 11.6 mg•dL −1 , P < 0.05) and blood cholesterol (20.0 ± 22.1 mg•dL −1 , P < 0.05), when compared with the values after the exercise program. Therefore, in the medium-term after sleeve gastrectomy exercise may contribute to prevent weight regain and to reduce fat mass, glycaemia, and blood cholesterol.

“…Bariatric surgery mediates changes to adipose depots, contributing to its effectiveness in treating obesity and its comorbidities [37,38]. Both RYGB and VSG result in comparable, significant loss of fat mass [39][40][41][42][43][44]. One recent study found that both decreases in visceral fat and subcutaneous fat tissue density are sustained one year following RYGB surgery [45].…”

There is a large body of evidence indicating that bariatric surgery provides durable weight loss and health benefits to patients who are obese and have comorbidities such as type 2 diabetes (T2D). However, there are still many questions related to mechanisms of metabolic improvement, predictors of success/failure, and long term consequences, which need to be answered. More recently, there has been a particular interest in the modulation of taste and food preferences that occurs after bariatric surgery and how this affects weight loss in different individuals. Animal models as well as human studies have shed some light on the role of taste in changing food preferences and how these changes may affect weight loss after surgery. The goal of this review is to discuss the physiological and behavioral consequences of bariatric surgery as a treatment for obesity and T2D, with particular emphasis on recent studies describing bariatric surgery-induced modifications in taste perception and food preferences.

Sleeve Gastrectomy and Roux-en-Y Gastric Bypass Lead to Comparable Changes in Body Composition after Adjustment for Initial Body Mass Index

Abstract: Excess weight loss is highly influenced by the initial BMI. Total weight loss seems to be a better measurement tool abolishing initial weight differences. SG and RYGB do not differ in terms of body composition and weight loss 1 year after surgery.
