One example is cholecystokinin, which is produced in response to food by cells in the upper small bowel.

一个例子是胆囊，它是小肠上段细胞对食物产生反应而产生的。

Less energy expenditure makes you more lethargic, less cholecystokinin means more hunger, less leptin signalling means more hunger and more ghrelin also means you're hungrier.

更少的能量消耗更嗜睡，更少的胆囊、更少的瘦信号以及更的胃促生长都增加饥饿感。

The cholecystokinin makes its way to the gallbladder, the thin walled, green sac snuggling up against the liver, and signals it to squeeze out some bile through the cystic and bile ducts into the small intestine.

当胆囊到达胆囊（即位于右方肋骨下肝脏后方的梨形囊袋构造），胆囊在激信息的指引下开始，将胆汁通过胆囊管和胆管排入小肠内。

As an October 2011 study in the New England Journal of Medicine says: " Caloric restriction results in acute compensatory changes, including profound reductions in energy expenditure and levels of leptin and cholecystokinin and increases in ghrelin and appetite."

正如 2011 年 10 月发表在《新英格兰医学杂志》上的一项研究所说：“热量限制导致急性代偿性变化，包括能量消耗、瘦和胆囊水平的显著降低，以及胃饥饿和食欲的增加。”
