1 What is intermittent fasting and how does it work?

Fasting has been a constant of human life since time immemorial. In times of need, there was and still is often a lack of food. Even if this was more like starvation, as it was not known when food would be available again, it can be compared to conscious abstinence, today's fasting. In medicine, fasting was discovered at the beginning of the 20th century to improve quality of life and life expectancy. It is often used as a diet to lose weightbut it can do much more, which we will look at in more detail in the blog article.

Intermittent fasting also has evolutionary roots. In the early days of mankind, the diet depended on what hunters and gatherers could provide. Fasting was later called for whenever harvests failed, natural disasters occurred or hunting success failed to materialize. So there was always a need for days of fasting.

Today it is about controlled days of fasting resp. fasting periods at certain intervals of hours or days, that is, to eat and fast in a very specific rhythm on the day or in the week. Intermittent fasting does not mean that you can indulge excessively during the eating phases. Rather, it is about consciously abstaining from food and eating a balanced diet.

There are different models from which you can choose the one that suits you, your life situation and your diet. everyday life and your everyday life. Important for the success of the intermittent fasting is that you can integrate it firmly into your life and that the days of fasting adapt to your life and not the other way around!

1.1 What is the 16:8 method?

In this model, food intake is limited to 8 hours per day. The remaining 16 hours are spent fasting and only consuming calorie-free drinks. The 16 hours also include the night. Whether breakfast or dinner is omitted during the 16-hour fast can be decided individually. See also the fasting plan at 6.1 and 6.2. This is one of the most popular variants as dietfor weight lose weight or to help with diabetes to keep blood sugar levels low. The other models are also suitable for slimming or for diabetes suitable. The decisive factor is how the variants best fit into your diet. day into your diet.

1.2 What is the 5:2 method?

The 5:2 principle involves eating a normal, balanced diet on 5 days and fasting on the remaining two days. On the fasting days a maximum of 800 calories are consumed. The fasting days do not have to be consecutive and can vary from week to week. On the fasting days you could, for example classic juice cleanse from LiveFresh to fall back on. In the section 6.3 you will also find a suitable example plan with healthy recipes for the 5:2 method.

1.3 What is the 1:1 method?

Another option when intermittent fasting is the 1:1 rhythm or alternating fasting, i.e. days with a normal diet alternate with fasting days on which the calorie intake is reduced to 800 calories or less. The classic juice cleanse from LiveFresh. In this variant, the calorie intake is greatly reduced over the course of the week, so that weight loss can be achieved as quickly as possible. An example plan with delicious and healthy recipes can be found in the section 6.4. The 1:1 variant is also very suitable for switching to the 5:2 or 16:8 method after the initial weight loss.

1.4 What needs to be considered during intermittent fasting?

A longer fasting phase results in lower insulin levels, greater weight loss and a greater reduction in blood sugar levels with diabetics. Therefore, if you have a pre-existing condition, especially if you are taking medication such as diabetes should always consult their doctor and, if necessary, adjust their medication accordingly.

It is also very important that you take your protein requirements into account when 16:8 method during the day and then spread it over the remaining meals. With the 5:2 and 1:1 fasting methods, you should also cover your protein requirements on the non-fasting days in order to prevent cravings and a "yo-yo" effect. On average, an adult needs 1 g of protein per kilogram of body weight. For a 60 kg woman, this means 60 g of protein per day. 20 g of protein can be found in 80 g of uncooked lentils or 25 g of pea protein powder, for example.

You should also always pay attention to how your body feels and try out which type of fasting suits you best and makes you feel most comfortable. Women in particular should make sure that their stress levels do not increase too much as a result of long periods of fasting, which can lead to hormonal imbalances. As a rule, most women feel most comfortable with the 16:8 principle, in which dinner is omitted, due to the hormone balance. Feel free to try out what feels best for you. 

2 What happens in the body during intermittent fasting?

Intermittent fasting is more than just a dietas it is said to have many healing effects. Many users observe an improvement in their body image and a weight reductionwhereby the interfall fasting its good reputation for slimming has gained.

In the best case scenario, this protects us from diseases or bacteria. It is important to provide the body with high-quality building materials during the eating phase, such as protein and healthy fats.

Some fasting enthusiasts also report that they feel fitter, "lighter" and more alert than before - in other words, healthy. The ability to concentrate also benefits many fasting people.

But even when used temporarily Intermittent fasting can be a good impulse for a change in diet, as you develop a much finer feeling for your food intake and for what your body really needs.

3. how long can intermittent fasting be carried out?

Intermittent fasting with the 16:8 and 5:2 methods can be carried out as a long-term dietary change, without a time limit. With the 1:1 principle, the calorie deficit over the week is very large, which is why this variant is a good way to get started and then switch to the 5:2 or 16:8 method in order to slowly reduce or maintain your weight and improve your health and well-being in the long term.

Die häufigsten Fehler beim Intervallfasten

  1. Aussuchen der falschen Variante
    Wer seine persönliche Fastenvariante findet, die sich gut in den Alltag
    integrieren lässt, bleibt auch länger dran. Außerdem kann insbesondere das
    Weglassen von Frühstück bei manchen Frauen über längere Zeit zu einem
    Durcheinander der Hormone führen. Hier ist dann vielleicht eine andere Variante z.B. ohne Abendessen eine bessere Option (siehe Abschnitt 6.2). Finde die für Dich richtige und gesunde Variante.
  2. Falsche Erwartungen und Ungeduld
    Manchmal dauert es etwas, bis sich Dein Körper und Dein Stoffwechsel an die
    neuen, gesunden Bedingungen anpassen. Es können bis zu zwei oder drei Wochen vergehen, bis Du Dich an längere Essenspausen gewöhnt hast. Hab Geduld!
  3. Ungehemmt weiterschlemmen
    Auch in den fastenfreien Phasen sollte Du nicht ohne Ende Schlemmen. Wer
    abnehmen möchte, sollte darauf achten die gesparten Kalorien nicht gleich
    wieder drauf zufuttern. In der Fastenfreien Zeit solltest Du auf nahrhafte
    Lebensmittel mit wenig Zucker setzten und Dich vor allem nicht überessen. Iss
    am besten normal weiter, als hättest Du nicht gefastet.
  4. Zu wenig essen
    Oft ist die Motivation sehr groß und man möchte möglichst viel abnehmen.
    Das hat aber mehrere Nachteile: Wer zu wenig isst, fährt den Stoffwechsel
    herunter und senkt damit seinen Energieumsatz. Später droht dadurch der
    Jo-Jo-Effekt, der sich bei einer Diät häufig einstellt. Darüber hinaus sorgen
    Radikaldiäten dafür, dass Hunger und Unzufriedenheit zu ständigen Begleitern
    werden. Achte auch unbedingt drauf Deinen Eiweißbedarf von 1g/Kg Körpergewicht trotzdem zu erreichen, um Heißhunger und JoJo Effekt zu verhindern (siehe Abschnitt 1.4).
  5. Zu wenig Schlaf
    Schon eine schlaflose Nacht lässt unser Hungerhormon ansteigen und
    verleiten und dazu mehr zu Essen, als wir eigentlich bräuchten.
  6. Zu viel Stress
    Bei Stress produziert der Körper das Hormon Cortisol, das den
    Blutzuckerspiegel ansteigen lässt. Dieses Hormon begünstigt zugleich auch die
    Einlagerung von aufgenommener Energie in Fettdepots. Die Reduzierung von Stress ist somit ein elementarer Baustein, wenn es um das Wohlbefinden und das Abnehmen geht.

Frequently asked questions about intermittent fasting:

What can I eat during intermittent fasting?

During fasting, calorie-containing foods and drinks are avoided. However, make sure you drink enough. Preferably water and unsweetened tea or coffee. Artificial flavors and sweeteners should be avoided. Green tea contains catechins, which are said to have an appetite-suppressing effect.

To maximize the positive effects of intermittent fasting you should make sure you eat a balanced and varied diet during the so-called "eating phase". Plenty of colorful vegetables with a source of protein and high-quality fats form the basis here. Pay particular attention to your protein requirements (see section 1.4). You should avoid ready meals and sweets as much as possible. For a healthy diet you will find many tasty and healthy recipes and more information.

What can I drink during intermittent fasting?

During the so-called "fasting window" you can drink water, unsweetened tea or black coffee. If you feel the need for something salty, you can also drink broth. During the "eating phase" you can also drink other beverages with your meals. Between meals, you should again choose drinks that are as calorie-free as possible to keep your blood sugar levels low.

Can I drink coffee during intermittent fasting?

During the intermittent fasting you can also coffee drink. However, to avoid interrupting your fast, it should be black, i.e. without milk or sugar. For optimal sleep quality, you should drink your last coffee before 2 pm if possible.

How effective is fasting for 16 hours?

The 16:8 method is very effective in many ways. The health benefits are based on autophagy, the cell renewal process that is set in motion. In addition, the insulin level is low, which diabetes diabetes and can also reduce inflammation. The gastrointestinal tract is also relieved. However, the protein requirement for the whole day should still be met so that your body has enough building materials available and cravings are prevented. If your total calorie balance remains below your daily requirement, it is also suitable for weight loss.

How much weight can I lose with intermittent fasting?

How much weight you lose depends on the individual. Severe overweight that has existed for a long time or medication and metabolic diseases such as diabetescan affect the losing weight somewhat more difficult and slower progress. In most cases, a weight plateau is reached after a period of weight loss and you stop losing weight. It can then be helpful if you change your fasting regimen, i.e. the fasting method or your diet during the eating phase.

How long should you do intermittent fasting for?

How long you should intermittent fasting is up to you and your well-being. The 16:8 or the 5:2 variant is suitable for long-term fasting. The 1:1 method should be used more as an introduction to the other intermittent fasting methods or a healthy change in diet, as a very large calorie deficit is achieved.

Which intermittent fasting method is suitable for beginners?

If you have no experience of fasting, the 16:8 method is a good way to start. You can start by skipping dinner 1-2 days a week. After a few weeks, you can then slowly increase the number of fasting days or switch to the 5:2 or 1:1 method. However, if you have already been on a juice cleanse from LiveFresh you can also start directly with the 5:2 or 1:1 method.

How many meals during intermittent fasting?

With the Intermittent fasting after the 16:8 method you can eat 2-3 meals in the 8-hour eating window. It is important that you still cover your protein requirements during the day and then distribute them over the remaining meals (see section 1.4).

What side effects can occur with intermittent fasting?

You may feel hungry, especially at the beginning. However, if you get used to the fasting rhythm, drink enough and follow our other tips below (see question: What can I do if I feel hungry during intermittent fasting?), then your feeling of hunger should soon improve. You may also experience occasional headaches or tiredness, especially if you haven't drunk enough. In most cases, broth or a glass of water with a pinch of salt will help to balance your electrolyte levels. If you feel stressed by fasting, you may not have chosen the right method or it simply doesn't fit into your everyday life. Take another look at the section 5. Who is intermittent fasting not suitable for? . Women in particular should be very careful here and choose the right method to avoid upsetting their hormone balance.

What can I do if I feel hungry during intermittent fasting?

The feeling of hunger does not usually last long, but comes in waves and then disappears again. It helps to keep yourself busy during the fasting phases. During a hectic working day, you won't have much time to think about food.

There are also natural aids that can suppress hunger:

  1. WaterA glass of water first thing in the morning can curb the feeling of hunger. Sparkling mineral water can provide relief from loud stomach noises
  2. Green teaGreen tea contains antioxidants that can stimulate the metabolism, but also catechins that curb the appetite.
  3. CinnamonStudies have shown that cinnamon slows down the digestive process and suppresses hunger. It can also have a positive effect on blood sugar. Cinnamon can be added very well to tea or coffee
  4. coffeeThe antioxidants in coffee have been shown in studies to have a hunger-reducing effect. In addition, the caffeine in coffee can stimulate the metabolism and fat burning.

The most common mistakes in intermittent fasting

  1. Choosing the wrong variant
    If you find your own personal fasting variant that can be easily integrated into your everyday life, you will stick to it for longer. In addition, skipping breakfast in particular can have a negative effect on some women. longer lead to hormonal imbalances. In this case, a different variant, e.g. without dinner, may be a better option (see section 6.2). Find the right one for you and healthy option for you.
  2. False expectations and impatience
    Sometimes it takes a while for your body and metabolism to adapt to the new, healthy conditions. It can take up to two or three weeks before you get used to longer breaks between meals. Be patient!
  3. Continue to feast uninhibited
    Even in the non-fasting phases, you should not feast without restraint. If you want to lose weight, you should be careful not to eat the calories you have saved straight away. During the non-fasting period, you should focus on nutritious foods with little sugar and, above all, not overeat. It is best to continue eating normally, as if you had not fasted.
  4. Eating too little
    People are often very motivated and want to lose as much weight as possible. However, this has several disadvantages: If you eat too little, you slow down your metabolism and reduce your energy turnover. This can lead to the yo-yo effect that often occurs when dieting. In addition, radical diets ensure that hunger and dissatisfaction become constant companions. Make sure you still reach your protein requirement of 1g/kg body weight to prevent cravings and the yo-yo effect (see section 1.4).
  5. Too little sleep
    Even one sleepless night causes our hunger hormone to rise and tempts us to eat more than we actually need.
  6. Too much stress
    Under stress, the body produces the hormone cortisol, which causes blood sugar levels to rise. This hormone also encourages the storage of absorbed energy in fat deposits. Reducing stress is therefore an elementary component when it comes to well-being and losing weight.
