如果你不习惯,16个小时不吃东西是很困难的. 24小时不吃东西是完全不可能的. 然而, 有了正确的准备和心态, 患者可以从禁食中获得巨大的好处, 包括优化血压, 改善血糖控制, 健康减肥等等.
我们来看看什么是快, the types of fasting options and the positive results that can be felt when a fast is completed properly.
跳转到一个特定的部分:
什么是快速?
Fasting is the voluntary restriction of food and/or drink intake for a certain period, 通常是16小时或更长时间. 有些类型的禁食可以持续几天甚至几周, 可能还包括摄入某些液体,如水或果汁.
虽然禁食的目的各不相同, one major health benefit of abstaining from calories for a prolonged period of time is the suppression of mTOR to 促进自噬 给身体一个急需的休息,让它重建得更强壮.
“Your gut cells will not rejuvenate if you’re constantly giving them food because they can never rest. 你所有的器官都需要休息,因为那是它们再生的时候. But they also need stress; you have to stress the muscle or organ so it can build back stronger. 给器官施加压力的方法之一是禁食.”
-Dr. 玛格丽特韦斯顿
什么是mTOR?
哺乳动物雷帕霉素靶蛋白(mTOR) is the regulating protein associated with fasting that responds to growth hormones and nutrients, 特别是氨基酸. 禁食时,mTOR活性被抑制,发生自噬. 自噬是机体对受损细胞的自然分解. mTOR也可以通过运动来抑制, 模仿热量限制和药物的补充剂.
“通过回收旧的或受损的细胞,身体变得更有效率. 如果你的细胞部分受损, the body can take those in and the cell will work better; the mitochondria become more efficient and make more ATP and you have more energy.”
-Dr. 玛格丽特韦斯顿
禁食期间的24小时消化时间
- 前4个小时: we use or store what we eat, which is why you don’t want to go to bed right after eating)
- 当它耗尽后,身体就会使用储存在肝脏中的糖原
- 16小时: Your body is using protein to make glucose for a short amount of time before switching to fat as a source
- 最长24小时 & 除了一旦糖原消失, we go into Ketosis — a process in which our bodies burn fat as fuel because the carbohydrate supply is exhausted
Note: Some people have a large amount of glycogen stored which means it can take a day or longer to get into Ketosis. 目标是在正常状态和这种状态之间轻松地来回切换.
禁食时允许吃什么?
这取决于你禁食的原因. 如果你这么做 优化肠道健康任何你需要消化的东西都会打破你的禁食. 黑咖啡和花草茶被认为是好的. 柠檬、醋和苏打水通常都可以.
Stevia and other natural sweeteners may be allowed but this depends on if they spike glucose levels, 这需要测试才能确定. 如果你注意到尖峰,应该避免使用.
骨汤能打破禁食吗?

如何为禁食做准备
如果澳洲幸运10正规官网开奖平台在挣扎, they can increase protein and healthy fat intake to help keep blood sugar levels balanced heading into their fasted state. 知道我们 真的 不用像别人告诉我们的那样每两个小时吃一次东西!
当你的禁食完成后,尽量不要摄入碳水化合物. 这是一个重要的时刻, 如果你这样做了, 你会错过宝贵的重建期, you could experience 脑雾 and you will also likely need to take a nap right away.
“你需要不断练习,不断进步! 慢慢开始是可以的,24小时禁食是一个伟大的目标. Ghrelin – the ‘Hunger Hormone’ — goes up when you’re hungry but goes right back down if you don’t eat. You have the same hunger that you would feel not eating lunch if you didn’t eat dinner. 它不会累积起来. 如果你能保持忙碌,你就能度过难关!”
-Dr. 玛格丽特韦斯顿

打破神话:消除关于禁食的错误信息
![关于禁食的常见误解](http://plfsng.e-mizu-ibaraki.com/wp-content/uploads/2023/12/FOL_4437-819x1024-1.jpg)
“我做不到,因为我的血糖降得太低了.”
This can be indicative of poor metabolic health and they need to fix their daily eating habits and then they would be able to handle it, 但他们必须慢慢开始,花更多的时间准备.
It’s helpful for these individuals to use a continuous glucose monitor to gauge their blood sugar. Knowing that your blood is quantitatively in the right zone can help keep you less anxious and more motivated. Some physical symptoms of “low blood sugar” early on may actually be mental — shaking, 脑雾, 易怒, 等.
你可能会经历皮质醇的增加, 禁食16 - 20小时后的生长激素和去甲肾上腺素. 这会导致更多的能量,并可能导致某人变得摇摇欲坠.
“我要失去所有的肌肉.”
在禁食期间,你的生长激素实际上会增加. 然而,这使得你如何开斋更重要. 你刚刚经历了一些自噬. 你已经分解了你体内的一些坏细胞. Your muscles act like a sponge with the increase in growth hormone — if you give them what they need (lean meats, 健康的脂肪, 更少的碳水化合物)-你会建立更好的肌肉细胞和更多的力量.
“禁食不是又一种时尚吗?”
No — humans have actually been fasting and experiencing the benefits of it forever. We didn’t have grocery stores before and would often go for long periods of time without eating. A recent study found a significant improvement in 10-year coronary heart disease risk among individuals who participated in fasting 作为斋月的一部分. 斋月庆祝活动已经持续了14个多世纪.
“禁食会破坏我的新陈代谢吗??”
事实恰恰相反! Multiple studies have found that we gain a metabolic boost from short-to-mid-length fasts, including this one which found that the metabolism of patients who underwent a three-day fast was 最后上涨了14%.
