    Background: The evidence supporting the benefits of early exercise in post-bariatric patients is growing. This study analyzed the effects of early exercise (1-week post-bariatric surgery) on body composition in patients with overweight and obesity 1 month after surgery. Methods: Thirty patients (age 36.5 ± 12.3 [range, 18-65] years; body mass index [BMI], 36.2 ± 12.3 kg/m2, range, 29-48) who underwent laparoscopic sleeve gastrectomy for bariatric surgery were instructed to participate in an exercise training program initiated on day 3 post-surgery and to follow a recommended protein intake of 60 g/day. After 1-month post-surgery, patients were stratified into those who adhered to exercise recommendations and those who did not. Pre- and post-differences in total weight loss (TWL), skeletal muscle mass (SMM), fat mass (FM), and visceral fat mass (VFM) were compared. Results: TWL, SMM, and FM loss were similar between non-adherent and adherent subjects (10.2 ± 3.5 kg and 11.9 ± 3.6 kg; p = 0.2; 2.9 ± 1.0 kg and 3.2 ± 1.2; p = 0.2; 6.2 ± 2.1 kg and 7.5 ± 3.6 kg; p = 0.2, respectively), whereas VFM was markedly reduced in the adherent group (29.9 ± 18.2 cm2 vs 14.6 ± 9.4 cm2; p = 0.01) compared to the non-adherent group. When the group was divided according to adherence to exercise and protein intake or non-adherence to both conditions, there was a significant difference in TWL, FM, and VFM losses (p < 0.05). In contrast, no differences in SMM were found. Conclusions: Early exercise training accelerated visceral fat mass loss during the initial recovery period in patients after bariatric surgery. Additionally, adherence to daily protein intake recommendations can increase total body weight and fat mass loss.

    Early Exercise Boosts Visceral Fat Loss Post‑Bariatric Surgery in the First Month

    This letter to the editor addresses critiques of a clinical study evaluating the efficacy of an early, counseling-based physical exercise intervention in post-bariatric patients. The authors highlight the paucity of research regarding proactive modification of body composition within the initial postoperative month, focusing particularly on visceral adipose tissue mass. The implemented protocol consisted of a home-based, unsupervised resistance training regimen employing elastic bands, initiated between postoperative days 5 and 7, following individualized in-hospital familiarization and audiovisual instruction. The intervention demonstrated high feasibility, safety, and clinical applicability, especially for populations with limited access to direct supervision during the early postoperative period. No adverse events were reported. The significant reduction in visceral adiposity observed is underscored as a clinically relevant proxy for improved metabolic risk profile. The use of subjective scales of perceived exertion (such as the Borg Scale) is justified when objective monitoring devices are unavailable. The authors recommend that future research prioritize the identification of determinants influencing patient adherence to exercise prescription within post-bariatric rehabilitation frameworks, aiming to optimize therapeutic outcomes.
