After a bariatric surgery, food intake is reduced. Patients should favor proteins to avoid loss of muscles. The guidelines recommend a minimal protein's intake of 60g per day. But this goal is achieved only for 55 to 60 % patients 4 months after surgery and 50 à 65 % patients at one year.~Protein assistant is a software which can calculate the amount of proteins eaten per day and can propose solutions if the intake is insufficient.~The main objective of this study is to evaluate the effect of the use of Protein Assistant on the daily protein intake in obese patients who underwent a bariatric surgery (in the 3 months following surgery).~Protein Assistant is suggested 1 month after bariatric surgery on a digital tablet. The patient is educated to use Protein Assistant. The patient has to complete a dietary record every 2 weeks during 2 months. The aim is to intake 60g per day. If the aim is not reached, Protein assistant suggests qualitative and/or quantitative solutions.
The aim of this study is to evaluate the effect of the use of Protein Assistant on the daily protein intake in obese patients who underwent a bariatric surgery (in the 3 months following surgery).
