Summary

In this research, we hypothesize that post-operative monitoring implemented with a connected scale after the 1st year (weight nadir period) post obesity surgery (i.e. sleeve and RYGB) would reduce the percentage of patients with excessive weight regain (\>10% regain of lost weight) by improving the quality of follow-up and long-term results. To do this, we are carrying out a comparative study on 182 patients, controlled, randomized per patient, ratio 1/1, open, in two parallel arms. Patients will be followed for 12 months and divided into one of the following two groups: * Control group: Standard follow-up * Interventional group: Standard follow-up + weekly weighing with the "Body Comp Pro" connected scale During their follow-up period, patients in the intervention group will have to weigh themselves at least once a week using the "Body Comp Pro" connected scale. The information will be transmitted to the investigation team via a secure platform available 24 hours a day. Alerts will be generated from a weight regain \> 5% of the baseline weight, allowing early management of weight regain.
