很多肥胖者总有“吃不饱”的感觉,哪怕饭后也抑制不住胃口。最新研究发现,其原因在于肥胖者体内控制食欲的胰高血糖素已经失效。人体血糖低时,胰高血糖素分泌增多而胰岛素减少,血糖高时胰高血糖素分泌减少而胰岛素增多。此外,胰高血糖素还可以影响体内调节食物摄取的关键激素——胃饥饿素,通过调节人体的饥饿感来控制食欲。德国柏林沙里泰大学医疗中心研究人员对11位肥胖者、13位I型糖尿病患者和13位瘦人进行对比试验,随机给他们注射胰高血糖素或安慰剂,
Many obese people always have “enough to eat” feeling, even after a meal can not suppress the appetite. The latest study found that the reason is that in obese people control appetite glucagon has failed. When the human body is low in blood sugar, the glucagon secretion increases but the insulin reduces, the high blood sugar reduces the glucagon secretion and the insulin increases. In addition, glucagon can also affect the body’s key hormone regulating food intake - ghrelin, by regulating the body’s hunger to control appetite. Researchers at the Salih Carey University Medical Center in Berlin, Germany, compared 11 obese subjects, 13 type I diabetic patients and 13 lean subjects with randomized injections of glucagon or placebo,
