What is juice fasting?

Juice fasting is one of the methods of therapeutic fasting and is a somewhat milder form of strict water-tea fasting and is therefore easier to integrate into everyday life. You drink a glass of freshly squeezed fruit or vegetable juice five to seven times a day, about one to one and a half liters in total. That corresponds to about 750 kilocalories (kcal). In addition, the body needs just under three liters of water or herbal tea every day.

In the morning, at noon and in the evening you dilute the juices with water and drink them slowly. They should not be washed down quickly; every small sip should be saliva-insulated so that the digestion of the nutrients is easier.

In addition to their typical aromatic substances, fruit and berry juices contain a higher proportion of fruit and grape sugar as well as plenty of potassium, which stimulates the excretion of toxins and acids via the kidneys, lungs and skin.

Make or buy juice yourself

For beginners in juice fasting, there are, for example, various citrus fruits whose varieties are easy to squeeze. Numerous vegetable juices are now also available ready-pressed in bottles or in tetra packs in the supermarket. Health food stores and health food stores offer a larger selection, where medicinal plant juices are also offered in organic quality.

The juices should be natural and unsweetened. You can use a juicer to make these yourself, experiment with it and mix different types of fruit and vegetables, such as orange and carrot or apple and sauerkraut, depending on your taste.

How vegetable juices affect health

Instead of freshly squeezed juice, juices from fermented vegetables are often used, for example sauerkraut juice instead of cabbage juice. If there is a tendency to constipation, they have an increased effect. The combination of nettle, artichoke and potato juice has also proven itself. Nettle flushes the body, artichoke gets the liver going and potato juice regulates digestion and alleviates symptoms caused by too much stomach acid.

Juice fasting with medicinal herbal juices

Juice fasting with medicinal herbal juices is popular. The Swiss plant researcher and pharmacist Dr. Walther Schoenenberger more than half a century of his life. Schoenenberger was firmly convinced that they were helpful against the development of lifestyle diseases such as joint problems, gout and digestive problems, as well as signs of wear and tear and age.

Lose weight with a juice fast

With juice fasting, solid food is avoided, but the fruit and vegetable juices provide the body with all the important vitamins, minerals and trace elements. With a duration of a maximum of three weeks, deficiency symptoms are not to be expected. Time-limited juice fasting is also considered a great way to lose weight.

Due to the heavy water loss, the weight can shrink by up to three kilograms in the first week of juice fasting. After that, progress is slower at around two kilograms per week.

Side effects of juice fasting

As with any other fasting method, the first three days of juice fasting are a bit critical due to the change in metabolism. There may be a fasting crisis with weakness or headache. From the fourth day onwards, these symptoms usually go away and you no longer feel hungry. If you have a sensitive stomach, you can add some oat, rice or flaxseed gruel to the juices, which will make them easier to tolerate.

See a doctor before juice fasting

You shouldn't go on a juice fast for more than three weeks without medical supervision. In addition, a doctor should generally be consulted before each fasting cure in order to clarify whether the individual state of health allows a fasting cure.

If you experience diarrhea, nausea or flatulence after consuming fruit and fruit juices, you may be fructose intolerance. In this case, you should replace fruit juices with vegetable juices. In contrast to fruit, most vegetables are well tolerated if you are fructose intolerant because they often contain much less fructose.
