"The 30-day period of Ramadan triggers a biological transformation. Here is a breakdown of how your body reacts:"
Phase 1: The Transition (Days 1-2)
The body enters the "fasting state" 8 hours after the last meal. Once glucose is depleted, it begins burning stored fats. Initial side effects like headaches and lethargy are common.
Phase 2: Adaptation (Days 3-7)
The body adjusts to the new routine. Fat breakdown accelerates, providing energy but increasing the risk of dehydration. Maintaining electrolyte balance during Suhoor and Iftar is essential.
Phase 3: Healing (Days 8-15)
As the body fully adapts, the digestive system rests. Energy is redirected toward immune functions and cellular repair, enhancing the body’s ability to fight infections.
Phase 4: Detoxification (Days 16-30)
In the final stage, organs like the liver and kidneys undergo a deep detox. Focus and mental clarity peak. When managed correctly, this phase promotes weight loss while preserving muscle mass.
Bottom Line: While a 30-day fast is beneficial for cellular renewal, prolonged starvation can lead to muscle loss. Experts recommend intermittent fasting patterns for long-term health.
