Controlled Trial Evaluating the Efficacy of Protein Supplementation in the Short Term After Bariatric Surgery (PROTISLEEVE)

Randomized Controlled Trial Prospective Single-center Open Evaluating the Efficacy of Supplementation (Adapted to the Post-operative Period) Current Protein After Bariatric Surgery Like Sleeve Gastrectomy

The main objective will be to evaluate the effect at 5 weeks of nutritional management associated with protein supplementation (adapted to the post-operative period) on the maintenance of lean body mass at the whole body in obese patients after a sleeve gastrectomy.

Secondary objectives will assess protein intake, food safety, the effect of protein supplementation on body fat in the entire body and the metabolic rate and the impact on quality of life and post-operative joint pain.

Study Overview

• Status: Completed
• Conditions: Obesity
• Intervention / Treatment: Other: protein supplementation

Detailed Description

The main objective will be to evaluate the effect at 5 weeks of nutritional management associated with protein supplementation (adapted to the post-operative period) on the maintenance of lean body mass at the whole body in obese patients after a sleeve gastrectomy.

Secondary objectives will assess protein intake, food safety, the effect of protein supplementation on body fat in the entire body and the metabolic rate and the impact on quality of life and post-operative joint pain.

There is still no study evaluating the protein supplementation adapted patients after sleeve gastrectomy on maintaining lean body mass.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
No Intervention: usual dietary management; Control group: usual dietary management Following the intervention, the stomach of patients underwent many changes
Experimental: care of with usual dietary protein supplementation; Intervention group: Usual dietary management with protein supplementation (30g) in addition to the usual inputs	Other: protein supplementation; Protein supplementation : Protein intake of 30 grams of protein in addition to the usual inputs (to the recommended amounts of 60 to 120 g per day), upon the resumption of oral intake until the fifth week after sleeve gastrectomy.
