Purpose: Even in the Mediterranean countries, the adherence to the Mediterranean diet is every day smaller. The aim of this study was to evaluate the adherence to Mediterranean diet of morbidly obese patients before and after undergoing a sleeve gastrectomy. Materials and methods: A prospective observational study of all the patients undergoing Laparoscopic Sleeve Gastrectomy (LSG) as bariatric technique between October 2010 and May 2012 was performed. All the patients completed the KIDMED index, before surgery and 1 year after the intervention. KIDMED index assessed the adherence to the Mediterranean diet. Results: A total of 50 patients were included in the study. Before surgery, 30% of patients presented a poor adherence to Mediterranean diet, 64% an average adherence and 6% a good adherence, whereas 1 year after surgery 2% showed poor adherence, 58% an average adherence and 40% good adherence (p=0.02). A significant inverse correlation could be established between KIDMED score changes and weight loss (Spearman -0.357; p=0.008), total cholesterol (Spearman -0.442; p=0.003) and LDL-cholesterol (Spearman -0.464 p=0.002). A direct correlation could be established between KIDMED score and HDL-cholesterol increases (Spearman 0.562; p=0.001). Conclusions: Patients with better adherence to a Mediterranean diet showed greater weight loss and improvement of lipid profile 1 year after surgery.
