Fasting - the science of not eating

Fasting - the science of not eating

Imagine if you could completely reset your body. Not directly to baby, but rather to completely renewed functions, processes and programs. All the old burdens would be removed and you would be as fresh as a daisy on the inside. What would you give for that?

You can have it for free! This is the credo of many people who swear by fasting as a healing or detox method. It has now become a trendy topic, although it has actually been practised and recommended since time immemorial. And since then, opinions have been divided on self-imposed abstinence from food. What is the benefit, what forms there are and what you should look out for if you want to try fasting for yourself.

The following sections look at various fasting methods. We will discuss what they can do and what you should pay particular attention to. If you would like to try a fasting method, it is best to talk to your GP about it first and make sure that there is nothing to stop you from reducing your diet.

Between religion, myth and hype

Fasting. A term that is often simply associated with starvation. But if you delve into this world, you will discover a multifaceted concept that is shrouded in historical, religious and health legends. Losing weight, stopping ageing, cleansing the bowels or clearing the mind - these and many other sensational effects are said to be achieved by fasting.

The practice of fasting, which is deeply rooted in many cultures, has taken on different forms and meanings over the course of time. In its traditional form, fasting is often associated with spiritual or religious practices. It is considered a time of reflection, cleansing and new beginnings.

Modern approaches to fasting distance themselves from strictly religious aspects and instead focus on the physical and mental benefits. The approach has now achieved a status that is also finding more and more followers in today's health practices. They swear by it: It's not just about simply not eating. For them, fasting is a conscious decision to give their body a break and allow its functions to rest. They see the body as a system that can only really regenerate when it is not constantly busy digesting. Fasting as wellness for the organs.

What's the real benefit?

Fasting is not just a method for shedding a few kilos. Research is still ongoing, but it is believed that these health benefits, among others, are actually linked to abstaining from food:

  • Accelerate metabolism
  • Increase mental clarity and focus
  • Strengthening the immune system
  • Improving blood values, e.g. B. cholesterol and urea
  • Reduction of inflammation in the body
  • Improvement of heart health
  • Enhancing brain function
  • Increasing insulin sensitivity
  • Improvement of digestive health
  • Above-average longevity
  • Detox effects
  • Slowing down cell ageing

Sounds like an immense payoff - for literally not having to do anything about it. But stopping eating just like that? It's going to be difficult without a system.

The main thing is that the plan fits

Not all fasting is the same. There are actually different ways of eating nothing or little, and each has its own special features. The best-known methods are:

Intermittent fasting: The clear star among the fasting methods. Here, eating phases and breaks alternate in a specific pattern. The 16/8 method is popular, where you don't touch anything for 16 hours a day and eat normally for the remaining 8 hours. This is particularly convenient for anyone who simply wants to try out fasting without having to jump straight into the ice-cold water. There are countless variations of this method, including 20/4 (20 hours of fasting with a 4-hour eating window), 5/2 (i.e. five days of normal eating and two days of fasting), 24- or 36-hour fasting or alternate-day fasting (alternating days of eating and fasting).

Full fasting: This is where it gets more serious. Full fasting involves completely abstaining from solid food for several days to weeks. Water, unsweetened teas and selected broths from time to time are all that is allowed. This method is particularly intensive for beginners and should only be done with prior consultation.

Juice fasting: If you can't do without your fruity sweet tooth, this approach is best for you. Because instead of solid food, freshly squeezed juices are the order of the day here. You can use the colors as a guide: a colorful mixture of fruits and vegetables provides the body with the most important nutrients. But please don't cheat: Sugared juices from the supermarket are taboo here. We're talking about natural, unprocessed juices, preferably from your own blender.

Teildetox: A relatively gentle form of fasting. Here, certain foods such as sugar, processed foods or caffeine are removed from the plan. This is also ideal for the first steps into fasting, as this form is more like a change in diet. It definitely relieves the body.

Each of these methods has its advantages and disadvantages. The most important thing is to get to grips with the concept you have chosen and not fall into harmful patterns. After all, it's not about who can go the longest without eating. So if you're going into fasting territory, you should know that there are a few things to bear in mind.

Better not just go for it

As with everything to do with health, you should know what you are doing. Here are a few tips to ensure that fasting really works
and has no undesirable side effects:

Gentle preparation: Before you start fasting, your body should be slowly prepared for it. This means eating a little less after and
after each fast before going into a full fast. Because cutting out everything from one day to the next is unnecessarily hard. It's better to ease into it gently.

Individuality counts:What works for one person doesn't have to work for everyone. Allow yourself a few test phases and find your own fasting style.

Listen to your body's signals:Every body reacts to fasting differently. It is important to pay attention to your own physical signals.
If you feel weak or unwell, you should take this seriously. Fasting is not a competition and it is not about torturing yourself.

Enjoy and relax:Fasting can also be a time of rest and enjoyment. Take the opportunity to focus on yourself.

Drink enough:Water is your best friend during
on-fasting times. It helps to keep the body hydrated and supports the cleansing processes. So, drink water, sweetened teas or broths regularly.

Seek medical advice:Especially if you have a medical condition or are taking medication, it is advisable to speak to a doctor beforehand. Fasting can have an impact on various bodily functions - so it is better to be on the safe side.

Re-enter cautiously:After fasting, it is important to slowly get your body used to solid food again. So don't plan a
five-course meal straight away, but first try some easily digestible food.

With these tips in mind, fasting can be an enriching experience.
But what to do if it's tougher than you thought? Don't worry. Especially at the beginning
you should be gracious with yourself and not force the change on your body. The task is to learn to understand your body and give it the time-out it needs to cope well. To ensure that the nutrient traffic light doesn't turn completely red or that there is a risk of a short-term drop in performance, you should always keep an eye on a few nutrients.

Nutrients for the basic supply

Vitamins and minerals:Vitamins and minerals such as vitamin C, potassium and magnesium should never be neglected. A few dried fruits will keep you replenished.

Good fats: Yes, fats are important, even when fasting. The unsaturated fatty acids found in nuts in particular are essential for the body. They provide energy and support the brain.

Fiber: Even if you eat less, you shouldn't forget about fiber. It helps digestion and keeps the system running smoothly. Dried fruit is another proven source here.

Protein: Nuts are little powerhouses when it comes to protein. During fasting, a little protein kick can help keep the body going.

Be careful with the quantity: Although nuts and dried fruit are great sources of nutrients, especially during fasting, you shouldn't overdo it. Because they are not stingy with calories either, which can mess up your fasting mode.

Nothing beats body awareness

Fasting can be a fascinating journey that helps you to become more aware of your body and do it good. With the right information and optimal preparation, you can get off to a good start. But whether you want to give it a try or not - listen carefully to your body and find out whether going without food can really do you good. Either way ... the main thing is that you feel good.
