Many cultures and religions around the world fast throughout the year. While the duration, practice, and specific reasons differ, all fasts have the similar goals of showing sacrifice and cleansing oneself.
Religions and philosophies that practice fasting include: Buddhism, Christianity, Islam, Judaism, Taoism, Jainism, and Hinduism.
Muslims fast this month - Ramadan - from 10 minutes before Daybreak to sunset – about 15 hours – abstaining from eating, drinking and sex.
Do you practice fasting or do you like trying it ?

I live in a Muslim country but I am not a muslim. I tried to follow the fasting....nehh I didn't last long

Good try
Quran says; O believers! Fasting is prescribed for you—as it was for those before you—so perhaps you will become mindful ˹of God˺.
˹Fast a˺ prescribed number of days. But whoever of you is ill or on a journey, then ˹let them fast˺ an equal number of days ˹after Ramaḍân˺. For those who can only fast with extreme difficulty, compensation can be made by feeding a needy person ˹for every day not fasted˺. But whoever volunteers to give more, it is better for them. And to fast is better for you, if only you knew.

I believe (as I understand it) fasting is focused more on clearing ones mind than removing indulgence. If removing the indulgence is the focus, the fasting is a useless gesture.

Fasting is a method of centering oneself. Accompanied by meditation and chanting (aka prayer).
Non-religious people center themselves in similar ways.
Sitting in the dark listening to soothing music works for me.

Most of us in today's world exist in a life of turmoil, hustle and bustle.
Fasting/meditation allows us to bring our minds to a restful center of being.
If your goal is religious, it might mean it allows you to connect, with greater focus, on your God.

I can understand how fasting/meditation can be advantageous to sanity.
It defragments you.

Health Benefits of Fasting
Although fasting can be challenging and sometimes uncomfortable, the mental and physical benefits can:
• Boost cognitive performance
• Protect from obesity and associated chronic diseases
• Reduce inflammation
• Improve overall fitness
• Support weight loss
• Decrease the risk of metabolic diseases
• Benefit cancer patients — A recent study with mice and cancer showed that fasting during chemotherapy jump-starts the immune system and exposes the cancer cells. Ridding the body of old, toxic cells and replacing with new, healthy ones may be just the answer. Traditionally, cancer patients have been told to increase nutrients and caloric intake while undergoing chemotherapy treatments but this approach might now be under review.
If you are interested in trying fasting, please consult your doctor.

While food fasting is beneficial in many aspects. Water fasting for an extended period of time is definitely harmful. It's even funny how health articles in the Arab and Islamic world promote drinking water all the year and suddenly disappear during Ramadan

Scientific papers say;
No detrimental effects on health have as yet been directly attributed to intermittent negative water balance at the levels that may be produced during Ramadan fasting.
