What this study is about

This study will see if a low-cost dietary plan, based on the standard dietary guidelines of the American Society for Metabolic and Bariatric Surgery (ASMBS) and using locally available foods, can help patients lose weight and keep their lean body mass after bariatric surgery. It will also check if this plan can maintain healthy levels of important nutrients such as vitamin B12, iron, and vitamin D. Patients who have undergone bariatric surgery will be randomly assigned to follow either the low-cost diet or the regular hospital diet. Their weight, body composition, and nutrient levels will be tracked at baseline, and at 1, 3, and 6 months after surgery. The aim is to find out if this simpler, affordable diet, which follows international standards, works as well as the regular plan while being easier for low-income patients to follow.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.
