. Water fasting.
Water fasting isn’t something new, and has even been done during the time of the Prophet (Sallalahu alayhi wasalam). Revisit the hadith in point 6:
It was reported in Sahih Muslim that the Prophet, sallallahu ‘alayhi wa sallam, said to Abu Dhār, who had stayed near the Ka’bah and its coverings for forty days and nights with no food or drink other than (Zamzam): “How long have you been here?” Abu Dhār said, “I have been here for thirty days and nights.” The Prophet, sallallahu ‘alayhi wa sallam, said, “Who has been feeding you?” He said, “I have had nothing but Zamzam water, and I have gotten so fat that I have folds of fat on my stomach. I do not feel any of the tiredness or weakness of hunger and I have not become thin.” The Prophet, sallallahu ‘alayhi wa sallam, said, “Verily, it is blessed, it is food that nourishes.”
{Narrated by Imam Muslim, 2473}
Some of the positive benefits of a 48 hour Zam-zam fast are an increase in the number of blood platelets and increased immunity through an increase in white blood cells, as well as a detoxifying effect on the body. Murwiya (Zam-zam) also increases hemoglobin levels, which result in increased energy levels. Testimonials state that these fasts eradicate morning breath, and hunger pangs, also providing a noticeable nourishing effect on the body.
