Fasting: the old remedy splitting doctors and forum users

Fasting: the old remedy splitting doctors and forum users

Does going without food for days actually do anything? That question runs through a discussion that starts with a lecture posted on a forum and, message by message, turns into a tug-of-war between those who see fasting as a health tool with centuries of backing and those who consider it a fad with no scientific basis. The starting material is a video nearly an hour and a half long, one hour and twenty minutes of lecture, defending fasting as a central practice in all religious traditions and as a method for cleansing the body. From there, the topic branches out: metabolic benefits come up, along with personal experiences, supposed gurus of dubious credibility and even electronic devices that supposedly kill parasites with frequencies.

What the lecture that opens the topic says

The starting point is a video presented as a lecture on the benefits of fasting. Whoever shares it describes it as highly instructive and highlights three ideas: the relationship between the brain's energy demands and the stomach, the idea that all religions and the teachers of humanity have prescribed fasting, and a reflection on the awareness and sensitivity of the marginalized. It gets watched in parallel with other tasks, because the format allows it.

The first criticism comes quickly: the lecturer never talks about breakfast. For the person trinc the video, that is a crucial point, because reintroducing food after the fast determines the outcome. The complaint is no small matter: breakfast is the meal that breaks the fast, and nobody explains how to do it.

Those who fast and tell it in first person

The most detailed experience comes from a 36-year-old participant, slim and athletic, who trains in athletics and swimming with demanding routines. He did a fast with no prior preparation, guided by a couple of articles, aiming to eliminate toxins from a past of tobacco and alcohol abandoned six and twelve years earlier respectively. He had been a vegetarian for a year. His testimony, including doubts about how to reintroduce food, is the most complete in the material.

Another, briefer experience comes from Germany: an acquaintance does a fast of 15 days every year, takes vacation for it, undergoes a medical check-up beforehand and gets the doctor's approval. The results she describes are remarkable: more vitality, better hair and skin. The detail of the prior check-up marks an important difference from those who fast on their own.

The skeptical front: no evidence, no paradise

The opposition is organized on several fronts. The first is the lack of scientific evidence: they openly ask who these teachers of humanity are and where the studies are. The second is compatibility with physical work: how do you explain to someone digging ditches in August that they shouldn't eat until the afternoon? The third is muscle mass: they doubt that a prolonged fast is compatible with keeping an acceptable minimum.

Some also point out that the postwar generation went through hunger and hardship and, in many cases, lived very long lives. The paradox is used in both directions: some read it as proof that restriction lengthens life; others, as mere coincidence with no causal link.

The fasting business: gurus, courses and gadgets

The topic drifts toward the market that has sprung up around it. A supposed guru is mentioned who claims to absorb the water he needs from the air, refuses to be monitored in a center for two weeks and charges 900 euros for a few days of teachings in which he barely appears for a couple of hours. The conclusion of the person telling it is blunt: a charlatan.

In parallel comes the world of zappers, frequency devices based on Hulda Clark's theories. One person built one for 0 euros with components and a sound card, and another fell asleep with it on and proge up with a very unpleasant sensation. The usual protocol is 7-minute cycles with 15-minute breaks, and the advice is not to leave it on all night because the palms of the hands and feet conduct better and the risk increases.

Extreme diets and the problem of both extremes

The thread also discusses transition diets that end in fruitarian and raw food eating. One commentator is credited with claiming that starch is not digested, that nuts are not assimilated either and that avocado is poison. On nuts, the observation is empirical: if not chewed well, they come out whole in the stool. On avocado, it is noted that it is toxic to most animals except humans, who would have an enzyme to neutralize the toxin.

The most balanced position in the material comes at the end: stuffing yourself with sugars, refined flours and ultra-processed foods to exhaustion is as extreme as prolonged fasting, and both take a toll on health. The conclusion is that the problem is not fasting itself, but turning any practice into a religion.

In the end, the discussion leaves a curious picture: people who have gone days without a bite for years and swear they feel better than ever, alongside people who have never fasted and are convinced it is madness. The data still hasn't shown up. The convictions, on the other hand, are in ample supply.
