Cholesterol levels have long been thought to be mainly a factor of diet and liver function . But new research in mouse models shows that changes in ghrelin and in a ghrelin-inhibited receptor in the hypothalamus altered how much hdl went to the liver for processing and how much remained in the blood stream .
Research suggests inadequate sleep is associated with low levels of leptin , high levels of ghrelin and weight gain .
研究表明睡眠不足与低水平瘦蛋白,高浓度生长素和体重增加有关。
When the stomach is empty , it releases the hormone ghrelin , which communicates with the brain 's command centre , the hypothalamus .
当胃里空空如也,它就释放胃促生长素,这种荷尔蒙与大脑的命令中心下丘脑交流。
Food cravings and metabolism are controlled in part by hormones , such as ghrelin , which stimulates hunger and lowers energy use .
食欲与新陈代谢由激素,例如刺激饥饿感和降低能量消耗的饥饿激素部分控制。
And when the study subjects were getting less than six hours of sleep a night , their ghrelin levels rose from 75 nanograms per liter to 84 ng per liter .
当研究对象睡眠少于6小时,他们的饥饿激素水平从每升75毫微克上升到85毫微克。
The hormones , discovered about 15 years ago , are leptin , ghrelin , and the endocannabinoids .
15年前,人们第一次发现了这些激素,主要包括瘦素,饥饿激素,内源性大麻素。
And when the study subjects were getting less than six hours of sleep a night their ghrelin levels rose from 75 nanograms per liter to 84 ng per liter . Levels remained steady when subjects got plenty of rest .
The fruit suppresses the hormone ghrelin , which is responsible for hunger pangs .
果蔬能够抑制胃液的分泌,而这正是饥饿感的来源。
For instance , a gastric hormone called ghrelin , often dubbed the " hunger hormone , " was about 20 percent higher than at the start of the study .
以胃部一种名为生长激素释放肽,常常被称作“饥饿激素”的物质为例,它的含量会比研究开始之初高20%。
At least two factors may be involved : more waking hours in homes brimming with food and snacks ; and possible changes in the hormones leptin and ghrelin , which regulate appetite .
