A couple of the big ones are a hormone called leptin.

几个大的是一种叫做瘦素的荷尔蒙。

So when you lose weight, leptin levels drop.

所以当你减肥的时候，瘦素水平就会下降。

That makes sense for leptin, since it's based on the amount of fat you have.

那使得瘦素水平很有意义，因为它基于你所具有的脂肪量而产生。

The larger your fat cells are, the more leptin they produce.

脂肪细胞越大，产生的瘦素就越多。

One of the most important is leptin, a hormone secreted by your fat cells.

其中最重要的是瘦素，一种由脂肪细胞分泌的激素。

For example, various hormones like ghrelin, leptin, and insulin affect your hunger and you satisfy the hunger with food.

比如说，各种激素，像生长激素释放肤瘦素、胰岛素等会影响你的饥饿感，你会用食物来满足这种饥饿。

" We know from previous research that sleep deprivation causes leptin to drop and ghrelin to rise, so you're hungry."

从先前的研究得知，缺觉会导致瘦素水平下降，饥饿激素水平上升，所以会感到饥饿。”

This extra insulin can make you feel even hungrier as it will block your leptin signal, like we discussed before.

额外的胰岛素会让你感觉更饿，因为它会阻止你的瘦素信号，就像我们之前讨论的那样。

Insulin stimulates the body's fat cells to make another hormone called leptin.

胰岛素刺激身体的脂肪细胞产生另一种叫做瘦素的激素。

Its partner, leptin, tells us when we are full.

它的伙伴瘦素会告诉我们什么时候吃饱了。
