In addition to that
不仅如此
There has been some evidence
还有证据显示
That acute stress increases cortisol
短期压力会增加皮质醇的分泌
And among individuals who show the greatest reactivity to the stress
有的人面对高强度压力时
That's been determined as high reactors
表现出更强的反应力
When given the opportunity to eat after the stressor
当允许他们在经历压力之后吃东西时
Have been shown to actually consume more calories
他们摄入的热量也更多
So you can see here that
所以大家可以看出
These are the high reactors in response to a stress session
这里显示的是压力环节中的高压力因素
In this case
那么在这个案例中
It was performing a speech
高压力因素就是发表一次演讲
Kind of a standardized go-to-method for stress researchers
这是压力研究人员的一种标准测试方法
Not so much unlike this
和我现在的演讲没有多大区别
Although you do, you know it's in front of the panel
尽管演讲者面对的是一个专家小组
And it's evaluative in nature
专家小组对他们的表现进行评估
And it causes a robust stress response
所以这项任务会使他们产生强大的压力反应
I will talk more about that in the data that I illustrate
我一会儿会引用研究数据来说明这点
But these high reactors were also the ones
承受了高压力的测试对象
That consume the most calories
在获得进食机会时
When given the opportunity
摄入了更多的热量
This was compared to a controlled condition
这是和没有承受压力的
When they didn't undergo a stress
控制小组进行比较后的结果
And these high reactors did differ
因此高压力因素
From low reactors in the calories that they consumed
确实对人们的热量摄入产生了影响
So there does seem to suggest that
这似乎也意味着
The stress and the cortisol that's produced is also associated
压力和身体产生的皮质醇
With behavioral change in calorie consumption
影响了和热量摄入相关的行为方式
In addition to cortisol
除了皮质醇之外
The other mechanism that I want to note in this selected review
我还要提到的另一个作用机制是
Is the role of neuropeptide Y
神经肽Y抗体的作用
Kuo and colleagues and some elegant studies
2007年的自然和医学杂志上发表的
Published in 2007 in Nature and Medicine
郭及其同事的研究以及其他出色的研究
Showed that stress upregulates NPY
显示在不影响肾上腺糖皮质激素的前提下
In a glucocorticoid dependent manner
如果提高神经肽Y抗体的水平
Leading adipose growth
那么当给老鼠喂食高糖分和高脂肪的食物时
When mice were fed high sugar/high fat diet
它们的脂肪会增加
