These 11 things will help explain why your belly's been growling. 这11个原因帮你解释为什么你的肚子一直在咕咕叫。 You're dehydrated 身体缺水了 "Mild dehydration is often masked as feelings of hunger, when really your body just needs fluids," says Alissa Rumsey, RD, spokesperson for the American Academy of Nutrition and Dietetics. The confusion happens in the hypothalamus, the part of the brain that regulates both appetite and thirst. 注册营养师兼美国营养与饮食学会的发言人艾丽萨·拉姆齐说：“当你的身体真的需要补充水分时，轻度脱水经常让人感觉好像是饿了”。这种混淆的感觉发生在下丘脑——大脑里控制饥和渴的部分。 When dehydration sets in, wires get crossed in the hypothalamus, leading you to grab a bag of chips when you really need a bottle of water. "Prevent it by staying on top of your fluid intake, starting with a glass of water first thing in the morning," advises Rumsey. "If you feel hungry, and you haven't drank much that day, try drinking a glass of water and waiting 15 to 20 minutes to see if your hunger subsides." 当身体开始脱水，传送信号的神经在下丘脑交叉混乱，导致你其实只需要一瓶水、却抓了一包薯条。拉姆齐建议说：“你可以通过优先补充水分来避免这种情况，早上一起来就先喝一杯水。如果你感觉饿了、这一天喝水又比较少，那么喝杯水试试，再等15-20分钟看看饥饿感是不是减轻了。” |
