Fasting has been practiced for thousands of years, documented as far back as the ancient Greeks. Already Pluto was saying “I fast for greater physical and mental efficiency.” Natural practices are important for the future of human health and in recent years, fasting has become more and more popular. If you check the term "fasting" on Google Trends, you can see a significant increase in search results in recent years. It seems that more people are rediscovering the power of ancient traditions which can help us to live healthy and happy lives. As such, fasting has recently been restored as a popular method to help lose weight and improve health. However, not just fasting, which usually takes place over several days, but also intermittent fasting is gaining in popularity. Intermittent fasting is a deliberate eating cycle that includes a period of fasting, most typically between 12 and 16 hours. It is important to remember that intermittent fasting is not implemented solely for weight-loss, but also for its vast range of health benefits.
Now, as we are passionate about Matcha, the question comes up if we can consume and enjoy our favourite drink while fasting? In short, anything that contains any calories breaks your fast, so if you stick to water, green tea, Matcha tea, and even black coffee, then you are fine. It could even be argued that Matcha is beneficial while fasting, as it contains healthy nutrients. When you are fasting, however, you should not add any sugar, milk, plant drink or so into your Matcha, as this will break your fasting.
Anyone with a sensitive stomach, however, may prefer to enjoy Matcha together with some food, or at least not without having some food in the stomach. Green tea in general on an empty stomach can cause an upset stomach. The reason is that green tea has polyphenols (which are healthy), but these can increase stomach acid.
I personally must say that I cannot drink green tea on an empty stomach, as I then get an upset stomach. I can, however, and I do this every morning, drink my Matcha on an empty stomach, and I am perfectly fine.
