Coffee vs. Green Tea with Intermittent Fasting

I once said that the custom of drinking green tea was better for your health than that of coffee drinking, what about it during your intermittent fasting?

One of the reasons I thought the green tea culture was better was that you had tea with pickles while in the coffee culture you had coffee with sweets. However, it doesn’t apply if you drink coffee in the morning during your 16-hour fast because you just drink black coffee without sugar or muffins and donuts.

On the other hand, coffee has slightly more calories than green tea, so if you aim to reduce as many calories as you can, switching to green tea may be better as your morning drink. It probably doesn’t make much difference, so I wouldn’t worry too much about it.

Coffee also has more caffeine than green tea, so if you want to avoid caffeine, green tea is a safer choice.

Green tea has a polyphenol called catechin, and catechin is supposed to be good for autophagy, according to Dr. Tamotsu Yoshimori, the author of Life Science Nagaikisezaruwoenaijidai no Seimeikagakukogi. He was a co-researcher of Dr. Yoshinori Ohsumi, the 2016 Nobel Prize winner in Physiology or Medicine, and is one of the prominent experts on autophagy. If you are doing intermittent fasting to activate autophagy, having green tea might increase the effect.

Both coffee and green tea are considered to have health benefits but they affect different areas. While green tea enhances our alpha brain wave, coffee makes us more alert and energetic. In my case, I drink both.

I have coffee in the morning but in the afternoon, I switch to drinking green tea.

The reason I drink coffee in the morning is that I like coffee and it helps me cope with not eating throughout the morning more than green tea does.

I picked up this habit in France years ago and coffee has always been part of my morning routine.

When I went back to England two years ago, I picked up today’s English custom of drinking coffee in the morning and tea in the afternoon. And now I drink green tea instead of English tea in the afternoon.

Whatever the case is I wouldn’t worry too much about choosing coffee or green tea, if you are already doing intermittent fasting and eating the Ikigai Diet foods, you are doing plenty for longevity, and remember, being easy-going is one of the elements that centenarians have.  So, don’t worry and be happy.
