Fasting in Islam, especially during the month of Ramadan, is much more than just abstaining from food. It is a spiritual and physical journey, a purification of the soul, body, and mind. But what exactly are its effects on our well-being? Through Quranic revelations and scientific studies, let’s explore the hidden benefits of fasting.
Fasting in the Quran: a powerful spiritual act
Fasting is a divine prescription mentioned in several verses of the Quran. It is not just an obligation but also a means to draw closer to Allah and attain piety.
“O you who have believed, fasting has been prescribed for you as it was prescribed for those before you, that you may attain piety.”
(Surah Al-Baqara, verse 183)
This act of worship allows one to control desires, develop patience, and strengthen God-consciousness (Taqwa). By refraining from eating, drinking, and indulging in passions, a Muslim disciplines the soul and purifies the heart.
Strengthening the connection with Allah
Fasting reminds us of our complete dependence on Allah. Deprived of food and water, the believer feels the fragility of human existence and turns more sincerely towards Allah through prayers and dhikr.
The more sincerely one fasts, the stronger the sense of closeness to Allah, a deep serenity that is hard to explain but so powerful to experience.
The benefits of fasting on the body according to the Quran and science
While the Quran highlights the spiritual virtues of fasting, modern science also confirms its remarkable effects on health.
Detoxification and cellular renewal
During fasting, the body enters a state of “deep cleansing.” In the absence of food intake, it activates a process called autophagy, discovered by Japanese scientist Yoshinori Ohsumi, who won the Nobel Prize in Medicine in 2016. This mechanism helps eliminate damaged cells and regenerate new healthy ones.
The Prophet ﷺ said:
“Fasting is a shield.” (Hadith reported by Al-Bukhari and Muslim)
Indeed, it protects the body from many diseases.
Weight regulation and blood sugar balance
Contrary to common beliefs, intermittent fasting practiced during Ramadan can regulate metabolism and help with weight management. A study published in the New England Journal of Medicine found that intermittent fasting improves insulin sensitivity, reduces the risk of type 2 diabetes, and protects heart health.
Interesting fact: A 2019 study revealed that fasting can lower LDL cholesterol levels and prevent cardiovascular diseases.
The impact of fasting on the mind: enhanced mental clarity
Beyond its physical benefits, fasting also boosts brain function. It improves focus, memory, and emotional stability.
Better stress and anxiety management
Fasting reduces the production of cortisol, the stress hormone, promoting a state of inner calm. With fewer material distractions, there is more time for meditation, Quran reading, and self-reflection.
The result? A clearer mind, better focus, and a stronger connection with oneself and Allah.
Increased dopamine and productivity
Fasting stimulates dopamine production, a key neurotransmitter linked to motivation and well-being. This is why, despite the lack of food, many fasters report increased energy and productivity.
Personal experience: Since I started fasting with greater awareness, I have noticed an incredible sense of mental peace, a feeling of control, and better emotional management.
