一个月一次连续饿48小时

A 48-hour fast is a significant period of abstaining from food and can lead to a variety of physiological changes in the body. It's often undertaken as a form of prolonged intermittent fasting. Here's a breakdown of the effects:

Metabolic Shifts:

 * Glycogen Depletion and Ketosis: In the initial hours of fasting (typically 12-36 hours), your body primarily uses stored glucose (glycogen) for energy. After about 24 hours, these stores are largely depleted, and your body shifts into a state of ketosis. In ketosis, your liver converts fat into ketone bodies, which become the main energy source, especially for the brain.

 * Insulin Reduction: Insulin levels significantly decrease during a fast, allowing your body to access and burn stored fat more efficiently. This can improve insulin sensitivity over time.

 * Increased Fat Burning: With lower insulin and depleted glycogen, your body relies heavily on stored fat for fuel. This can contribute to weight loss.

 * Protein Sparing: While some protein breakdown can occur during prolonged fasting, the body attempts to conserve muscle tissue by increasing ketone production.

Cellular Processes:

 * Autophagy: A 48-hour fast is generally long enough to trigger autophagy, a cellular "self-cleaning" process where the body breaks down and recycles damaged or old cell components. This is thought to have protective effects against various diseases and may slow cellular aging.

 * Cellular Repair: The body takes a break from digestion, allowing it to focus energy on repair and regeneration processes.

Other Physiological Effects:

 * Weight Loss: A 48-hour fast represents a significant calorie deficit, which can contribute to weight loss.

 * Improved Blood Sugar Control: By reducing insulin levels and improving insulin sensitivity, fasting can help manage blood sugar levels and may be beneficial for those at risk of type 2 diabetes.

 * Reduced Inflammation and Oxidative Stress: Some studies suggest that fasting can reduce markers of inflammation and oxidative stress in the body, both of which are linked to chronic diseases.

 * Cardiovascular Health: Fasting may lead to a decrease in heart rate and systolic blood pressure. Some research also indicates improvements in cholesterol levels and protection against free radical damage to the heart.

 * Brain Function: Research on 48-hour fasting has shown increased parasympathetic activity (indicating a more relaxed state), decreased resting frontal brain activity, and improved cognitive functions like mental flexibility. However, some studies also report increased anger.

 * Changes in Hormones: Prolonged fasting can lead to an increase in growth hormone and glucagon, and a decrease in thyroid hormones (T3/T4).

Potential Side Effects:

 * Hunger: This is the most common side effect and can be intense.

 * Fatigue and Dizziness: These are common due to low blood sugar and the metabolic shift.

 * Headaches: Often experienced during the initial phase of fasting.

 * Irritability and Mood Changes: While some cognitive functions may improve, anger can increase.

 * Insomnia: Some people experience difficulty sleeping or frequent waking.

 * Digestive Issues: Changes in digestive patterns can occur.

 * Dehydration and Electrolyte Imbalance: It's crucial to stay well-hydrated during a fast.

 * Muscle Wasting: While the body tries to conserve muscle, some breakdown can occur, especially with very prolonged or frequent fasting.

Important Considerations:

 * Listen to Your Body: Severe side effects like extreme dizziness, exhaustion, or fainting indicate that the fast may be too much for your body.

 * Gradual Approach: It's recommended to start with shorter fasts (e.g., 12-16 hours) and gradually work up to a 48-hour fast to allow your body to adapt.

 * Not for Everyone: Certain individuals should avoid prolonged fasting, including pregnant or breastfeeding women, individuals with underlying medical conditions (like diabetes, kidney disease, heart disease, or eating disorders), and those on certain medications. Always consult a healthcare professional before attempting a 48-hour fast.

While research on the benefits of fasting is ongoing, it's clear that a 48-hour fast induces significant physiological changes. It's a powerful intervention that should be approached with caution and, ideally, under medical guidance, especially for individuals new to fasting or with health concer

饿两天目的是什么呢?

这种瞎抽风的折腾自己一概不赞许。

根据医学研究饥饿48小时后长寿基因开始表达,自吞噬作用开始清理废旧老死细胞,

饿7天器官就开始衰竭。农耕文化的人六三年挨饿是死了不少人的。还是别瞎折腾

哈哈,万一没长寿基因,饿两天岂不启动了短寿基因。。。

多运动点比啥都强

哈哈,不知道启动了什么基因就完了

60,61年左右饿死不少。后来国民经济基本好转,不知道是否启动了没有饿死的人长寿基因

科学还是有一定可信度的

就是让身体生物化学系统休假。身体有脂肪和糖愿可以消耗。而整个系统都不需要忙碌外来食物,做一下内务

握手。我也是一两个月一次48小时断食,每周一两次24小时,没有任何不适,照常健身和上班

只是24小时左右会有想吃东西的cravings, 但过了这个时段就没有了。

Fasting for 24 hours can affect your eyes, primarily due to

dehydration and potential fluctuations in blood sugar. This can lead to dry eyes, blurry vision, and in some cases, changes in intraocular pressure (IOP)

我觉得饿一顿还是可以的,饿两顿就太多了。搞不好会饿出别的毛病来。
似曾相識
沒苦硬吃~~

饿48小时吃草都是香的,那还用去餐馆,门口的草坪就可以解决了。

要不你再找找医学研究,看有多少百岁老人是靠饿48小时表达长寿的?

貌似结果为零。

至少孤陋寡闻的我,没有听说过。

你, 你, 你 。。。 不会血糖太低吗?

当然不会,人体会自动调节血糖,糖原用完了开始分解脂肪,进入ketosis状态

建议你试试,断食时身清气爽的感觉会上瘾的

副作用之一是低血糖,那喝还是不喝糖水?

没想法这个话题对好多老中是陌生的,人家老印一周一天节食非常常见,慕斯林也有白天不吃东西的宗教习俗

其实断食老中自古就有,比如道教的辟谷,佛教的斋戒和过午不食,但现代老中这些年被折腾得特怕没吃的, 少吃一顿像天塌

现在很多研究仅着眼于某个“点”, 属片面“盲人摸象” 缺乏多面整体观。
