Can I drink other things besides water and herbal tea?

Our Buchinger Wilhelmi FASTENBOX is designed in such a way that you do not need to consume anything apart from water and the yoghurt that is not included in the box. Other than that, you don’t need to add anything.
Anything else you consume will usually have additional calories. With normal Buchinger therapeutic fasting, you have an average of 250 to 400 kcal per day. With our box, it is about 600 kcal per day, due to the oils it contains.
Oils or fats act as a booster during fasting and ensure that the body stays in the ketogenic metabolism and you are still supplied with enough energy to continue doing your everyday tasks.
To stay in fasting metabolism, it is important not to exceed your daily calorie count, otherwise your body will go out of fasting metabolism and you would miss your goal.

If you want to have something with flavour for a change, we recommend reaching for our herbalessence or adding fruit to your water to give it a different taste. On a small scale, low-energy and highly diluted vegetable juices are also fine. Unsweetened teas can also be drunk hot or cold.

Basically, however, we recommend sticking to the fasting plan so that fasting succeeds as it should.
