Further, it is known that excessive intake of fat causes not only obesity but also diabetes, hyperlipidemia, hypertension, arteriosclerosis and the like caused by obesity. In addition to visceral fat obesity, a condition that includes any two or more of hyperglycemia, hypertension, and lipid abnormalities is called metabolic syndrome (visceral fat syndrome), and there is a risk of developing heart disease or stroke. Due to its high cost, it has been regarded as a problem in recent years. As a therapeutic agent for obesity, for example, Xenical (registered trademark), which has an action of suppressing fat absorption from the intestinal tract by lipase inhibitory activity, is marketed as an obesity-improving drug. Such side effects are reported and are not necessarily safe (Non-patent Document 1).
