Obesity is a challenging health problem in the industrialized world and in recent population studies the prevalence of overweight, obesity and abdominal obesity is constantly increasing, reaching to an epidemic proportions. The excess of body weight is associated with a low-grade systemic inflammation and a cluster of metabolic alterations such as insulin resistance, hypertension and dyslipidemia, which is presumed to play a role in the development of cardiovascular disease and type 2 diabetes mellitus. It is now well-established that adipocytes secrete proteins (adipokines) that actively control energy homeostasis, glucose and lipid metabolism, neuroendocrine and cardiovascular function and inflammatory response. Excessive levels of some adipokines such as TNF-α and IL-6 can disturb the metabolism suggesting the adipose tissue as a link between obesity, low grade inflammation and insulin resistance. In obesity, sustained weight loss has several beneficial effects on lipid metabolism, glucose tolerance and arterial blood pressure. There have been an increasing number of obese patients requiring treatment (bariatric surgery and/or diet) for weight loss. The weight loss induced by bariatric surgery causes a reduction in the inflammatory state, increasing levels of adiponectin and GLP-1, which are all related to beneficial metabolic changes described above. GLP-1 is especially related to insulinotropic properties through induced expansion of insulin secreting B-cell mass and enhanced insulin secretion. GLP-1 acts also in insulin action enhancing B-cell glucose sensitivity contributing to glycemic control after surgical procedure. So our focus in this chapter is to emphasize metabolic and inflammatory profile in obesity and its metabolic changes after weight loss.

Keywords: Obesity, adipokines, inflammatory cytokines, insulin resistence, GLP-1, weight loss.
