Impact of a Low-Calorie, High-Protein Diet Before Bariatric Surgery for Adults with Morbid Obesity

What this Trial Is About

Obesity is a growing public health issue that can be difficult to treat through diet, exercise, and managing psychological challenges alone. Bariatric surgery is an option for patients with a body mass index BMI of 40 or higher, or 35 or higher with related health problems like type 2 diabetes or sleep apnea, when other treatments have failed. A common surgical challenge is the increased fat and size of the liver, which can complicate the procedure. This research evaluates the effects of a low-calorie, high-protein diet taken for four weeks before bariatric surgery. One group will follow this diet to reduce liver fat and size, while another group will not follow the diet. The diet aims to make surgery easier and safer by reducing fat load and improving surgical conditions. Participants will be monitored before and after surgery with assessments of diet tolerance, weight loss, muscle strength, quality of life, physical activity, digestive tolerance, and surgical outcomes such as operating time and complications. The study includes follow-ups up to three months after surgery and tracks hospital stay length and post-surgery complications, with the total observation lasting four months after surgery.
