Numerous studies have shown that drinking lukewarm water on an empty stomach is very important for maintaining health, but no one really knows why the Japanese believed in these recommendations while there was not such a mass response elsewhere.

Studies, summarized by practically all media (print and online), explained that regular drinking of water on an empty stomach helps with headaches, heart and vascular problems, asthma, gastritis, diarrhea, bronchitis ... And that's just the tip of the iceberg. Only when the Japanese started massively following the water diet did the real benefits show.

What is the Japanese water diet?

Before you brush your teeth, try to drink 640 ml of water. Yes, that's more than half a liter! The number is important because it is the average free volume in the stomach on an empty stomach, and it is important to fill the stomach with water, which is the only thing that has no calories (not even negative ones that would take energy away from the body).

The success of this diet is backed by statistics. In Japan, there was a significant decrease in the number of cases of gastritis, diabetes, and arthritis last year, all of which are diseases that can only be treated with water. Detailed analyses have shown the following:

• High blood pressure: To normalize your blood pressure, drink water on an empty stomach for 30 days. The first effects will be visible after one week.
• Gastritis: Drinking water for 10 days will be enough. Then wait 10 days and continue if necessary.
• Diabetes: Drinking water on an empty stomach for 30 days significantly reduces blood sugar levels.
• Arthritis: Drink water on an empty stomach for 3 days, then wait a week, and if you don’t notice any negative effects, continue drinking for at least two more weeks.

If you have more serious problems, consult your doctor about your intentions, as too much water in the body can cause other concerns.
