FASTING HOTEL Koyarunomori


What is Fasting?


About Fasting 1


What is fasting?

Fasting at our hotel is not a "fasting" program in which you take in no nutrition and only water, but a program in which you take in the minimum amount of calories and nutrients through such items as fermented drinks while avoiding solid foods, so that you can detoxify your body and mind.
Compared to traditional fasting, which often ends in failure and frustration, fasting at Koyarunomori is a detoxification method that can be adopted by a wide range of people because it is less likely to cause hunger, stress, headaches and nausea due to low blood sugar.

The Mechanism of Fasting

When we work hard, we get tired and efficiency decreases.
Just as we need a day off, our internal organs also need to rest.
By resting your internal organs through fasting, you will be able to restore their natural functions.
The enzymes secreted by the body are also the key to fasting.
Digestive enzymes, which are secreted when we eat, and metabolic enzymes, which are involved in immunity and vital activities, are secreted in the body, and one of these two enzymes takes priority over the other.
In other words, by making metabolic enzymes dominant over digestive enzymes through fasting, it is possible to promote immunity and recovery from fatigue.
