Scientists say that the ratio of sugar in the blood begins at 80-110 mg/100 cc, which is the normal ratio of sugar in the blood. But after fasting for six hours, this ratio goes down.
Here a marvelous miracle of the human body takes place, as the brain sends fast messages to the endocrine glands for help and energy supply.
The supra-renal gland produces a special hormone that incites the change of starch in the muscles and liver into sugar; and the thyroid gland also produces a special hormone that incites the sugar stored in the muscles and liver to get out and get consumed.
All of this happens because the ratio of sugar in the blood goes down after a six-hour Fast. Another gland, the pancreas, also produces a special hormone that incites the stored sugar to get out and get consumed.
If man were to consume all the sugar that he has stored in his muscles and liver, the fats, stored in the body, are broken down into sugar to be consumed by the body.
Scientific research confirms that the burning of fats increases during fasting hours, and so does the consumption of fats accumulated on the different parts of the body.
The amazing fact about the human body is that each 1kg of fat tissues needs 3km’s of capillaries through which the blood flows.
This is a heavy burden on the heart, for if a person’s weight is 10kg’s above normal, this means that he has 300km’s extra capillaries that have to be provided with blood by his heart.
Scientists confirm that physiology of the human body necessitates that man should abstain from food for certain periods of time enough for the first and second stages of food digestion to take place and to allow operations of the third stage to work well.
Fasting eases the first stage’s processes of food digestion and absorption, the second stage of food storage, and the third stage’s steps of burning and consumption of the stored energy in the body.
This means fasting is indispensable for mankind! And that is why Allah, Most Gracious, Most Merciful, says, “O you who believe! The Fast has been prescribed for you, as it has been prescribed for those before you, so that you may attain self-protection.” (Surat Al-Baqarah: 2:183).
