    BACKGROUND: Weight loss surgery is an established intervention for obesity and related conditions, ensuring sustained weight reduction and improved comorbidities. Post-bariatric surgery, maintaining nutritional adequacy and weight loss necessitates ongoing, intensive dietary support. This research aims to discern the impact of standard care vs. intensive dietary support on outcomes following bariatric surgery within an Asian demographic. This study aims to research the part that intensive dietary support plays in contrast to standard care in altering weight loss and BMI change following bariatric surgery.

    METHODS: A retrospective analysis of medical records from a Malaysian tertiary care hospital documented bariatric surgeries conducted from January 2020 to January 2022. Rigorous criteria selected 200 patients from 327, evenly split between standard care and intensive dietary support groups. The latter underwent six mandatory visits with a surgeon and a dietitian in the initial 3 months post-surgery. A dual-review mechanism was implemented for data interpretation, increasing robustness, and reducing biases in our findings.

    RESULTS: At 6 and 12 months, the intensive dietary support group exhibited significantly greater weight loss and BMI reduction (p < 0.01). Postoperative complications did not significantly differ between groups.

    CONCLUSION: In an Asian population, intensive dietary support enhances weight loss and BMI reduction compared to standard care after bariatric surgery.

    Metabolic surgery is an essential option in the treatment of obese patients with type 2 diabetes (T2D). Despite its known advantages, this surgery still needs to be introduced in Malaysia. In this prospective study, the pathophysiological mechanisms at the molecular level will be studied and the metabolomics pathways of diabetes remission will be explored. The present study aims to evaluate the changes in the anthropometric measurements, body composition, phase angle, diet intake, biochemistry parameters, adipokines, microRNA, and metabolomics, both pre- and post-surgery, among obese diabetic patients in Malaysia. This is a multicenter prospective cohort study that will involve obese patients (n = 102) with a body mass index (BMI) of ≥25 kg/m2 (Asian BMI categories: WHO/IASO/IOTF, 2000) who will undergo metabolic surgery. They will be categorized into three groups: non-diabetes, prediabetes, and diabetes. Their body composition will be measured using a bioimpedance analyzer (BIA). The phase angle (PhA) data will be analyzed. Venous blood will be collected from each patient for glycated hemoglobin (HbA1c), lipids, liver, renal profile, hormones, adipokines, and molecular and metabolomics analyses. The serum microRNA will be measured. A gene expression study of the adipose tissue of different groups will be conducted to compare the groups. The relationship between the 1HNMR-metabolic fingerprint and the patients' lifestyles and dietary practices will be determined. The factors responsible for the excellent remission of T2D will be explored in this study.
