Are there health benefits of fasting that modern science has recognized?

Fasting in Islam is prescribed primarily as an act of worship meant to build taqwa (God-consciousness), not as a health regimen, but researchers have since taken interest in patterns similar to Ramadan-style fasting — extended daily periods without food followed by an eating window. Studies on time-restricted and intermittent fasting have explored potential links to improved insulin sensitivity, cellular repair processes such as autophagy, and general metabolic markers, though this remains an active and evolving area of research rather than settled medical consensus, and results vary by individual and by how the fast is broken (a large, rich iftar can offset much of the potential benefit). It's worth remembering that Ramadan fasting is a religious obligation with built-in exemptions for those who are ill, pregnant, nursing, elderly, or traveling, and it should not be treated as a diet plan. Anyone with a medical condition — diabetes especially — should talk to their doctor before or during Ramadan about how to fast safely, or whether they are religiously exempt.
