Several researches has reported that diets rich in anthocyanins can prevent metabolic diseases. Obesity is caused by a long-term difference in energy intake and expenditure (i.e. positive energy balance), which leads to a rise in body mass and the accumulation of subcutaneous and visceral fat. Despite the fact that obesity is a risk factor for a variety of diseases, numerous human studies have found that visceral fat, or fat in the viscera, is the fat that is most closely associated to a variety of health problems [1,2]. Insulin resistance (IR) has been associated to a number of metabolic issues, including insulin resistance, non-insulin-dependent diabetes, hypertension, and dyslipidemia. Moreover, the pathophysiology of IR in obesity, as well as the processes that cause it, remain unexplained [3]. Under normal physiological settings, the insulin and glucagon levels of glucose in equilibrium are within a small range. It was assumed that it had been managed. The perception of the presence of a more complicated multihormonal system has shifted in recent years. The metabolism of glucose and lipids are also implicated. Adipokines (leptin, adiponectin, visfatin, resistin, and adipsin) secreted from adipose tissue, as well as GLP-1, ghrelin, and glucose-dependent insulinotropic polypeptide (GIP) secreted from the intestinal tract, all play a role [4].
