What the trial is, and whether it could suit you
Disruption of white adipose tissue (WAT) homeostasis during obesity is central to the development of associated cardiometabolic complications. Dietary supplementation with oleic acid in obese patients can limit these complications. Experimental data, obtained in preclinical models, suggest that the beneficial effects of oleic acid may protect the TAB by increasing cholesterol esterification. The NAMICO study aims to test this hypothesis using TAB biopsies collected from obese patients undergoing bariatric surgery who had previously undergone dietary enrichment with either a conventional oil or an oil rich in oleic acid.

* Bariatric surgery performed at Nantes University Hospital (CHU de Nantes).
Exclusion Criteria:
* • Modification of diabetes treatment within the past month.
* Ongoing or planned insulin therapy before bariatric surgery.
* Modification of lipid-lowering treatment within the past three months.
* Systemic corticosteroid therapy.
* Antiviral therapy (HIV).
* Dietary supplementation affecting lipid metabolism, including proactive margarine, Danacol, polyunsaturated fatty acid supplementation, or any other substance identified by the investigator.
* Exocrine pancreatic insufficiency.
* Pregnancy or breastfeeding.
* History of organ transplantation.
* Individual deprived of liberty or under legal protection (guardianship or trusteeship).
* Any clinical condition in which the investigator considers that inclusion in the study may harm the patient's health or compromise the proper conduct of the study.
