The objective of this work is to identify biomarkers of interest in patients with insulin resistance leading to early disorders of glycemic regulation. For this the investigators want to assay the insulin resistance marker Insulin Regulated Amino Peptidase serique (IRAPs), the plasma lipidome and inflammation markers in 2 populations of insulin-resistant subjects due to Dunnigan's inherited lipodystrophy or overweight/obesity and insulin-sensitive subjects with or without a glycemic regulation disorder objectified during an Oral induced hyperglycemia. The results of the IRAPs, lipidome and inflammation assays will be compared in insulin-resistant subjects, between normoglycemic, prediabetic and diabetic subjects. Correlations will be made between these markers and the deterioration of glycemic regulation as well as with known insulin resistance parameters (HOmeostasis Assessment Model (HOMA), Quantitative Insulin-sensitivity Check Index (QUICKI),Insulin Sensitivity Index (Isi) MATSUDA).
