All participants were weighed every week for 24 weeks, wearing light clothes to the nearest 0.1 kg, using a body composition analyzer. Height was determined during the first clinic evaluation using a fixed wall stadiometer to the nearest 0.1 cm, in standing position.

Intervention: Participants followed a liquid diet plan during the first week after the endoscopic bariatric procedure (Bioenterics Intragastric Balloon - BIB - or Primary Obesity Surgery Endoluminal - POSE -). Subsequently, subjects were randomly assigned either a Mediterranean-style or a protein diet plan. Energy intake was calculated according to the Spanish Consensus on Bariatric Endoscopy.

The hypothesis of this project is to analyze whether the Mediterranean-style diet is more effective compared with the open protein diet plans in weight loss and weight relapse in subjects with obesity who underwent endoscopic bariatric therapies.
