Assessment of Protein Intake in the First Three Months after Sleeve Gastrectomy in Patients with Severe Obesity.

An adequate protein intake prevents the loss of fat-free mass during weight loss. Laparoscopic sleeve gastrectomy (SG) jeopardizes protein intake due to post-operative dietary restriction and intolerance to protein-rich foods. The purpose of this study is to evaluate protein intake in the first three months after SG.
