Dr.
F. Azizi and his associates (ref.9) from the University of Medical
sciences, Tehran, Iran has reported the following. Serum levels
of glucose, bilirubin, calcium, phosphorous, protein, albumin,
FSH, LH, testosterone, prolactin, TSH, TI, and T uptake, as
well as prolactin and TSH responses to TRH were evaluated in
a group of nine healthy men before and on the 10th, 20th and
29th days of Ramadan. Mean body weight decreased from 65.4 +
- 9.1 to 61.6 + - 9.0 kg at 29th day. Serum glucose decreased
from 82 + - 4 mg/dl on the 10th day, and increased thereafter
(76 + - 3 and 84 + - 5 on the 20th and 29th days of fasting
respectively.) Serum bilirubin increased from 0.56 + - 0.17
to 1.43 + - 52 mg/dl on the 10th day, and decreased thereafter
(1.1 + - 0.4 on the 20th and 29th days). All changes returned
to basal values four weeks after fasting. There were no significant
changes in serum levels of Ca, P, protein, albumin, and any
of measured hormones. Prolactin and TSH responses to TRH were
also unaltered. He concluded than termittent abstinence from
food and drink for 17 hours a day for 29 days does not alter
male reproductive hormones, hypothalainic-pituitary-thyroid
axis or peripheral metabolism of thyroid hormones and physicians
caring for Muslims should be aware of changes of glucose and
bilirubin during Ramadan.
Therefore
it is concluded from the above two studies that Islamic fasting
does not cause any adverse medical affect and may have some
beneficial effect on weight and lipid metabolism.
Why
Islamic Fasting Is Different Than Other Types of Fasting (7)
As
compared to other diet plans, in fasting during Ramadan, there
is no manlutrition or inadequate calorie intake since there
is no restriction on the type or amount of food intake during
Iftaar or Suhur. This was confirmed by MM Hussaini (6) during
Ramadan 1974 when he conducted dietary analysis of Muslim students
at the University of North Dakota State University at Fargo.
He concluded that calorie intake of Muslim students during fasting
was at two thirds of NCR - RDA.
Fasting,
in Ramadan is voluntarily undertaken {i.e. although it is
obligatory in Islam, it is not forced upon anyone by another
person or group of people}. It is not a prescribed imposition
from a physician. In the hypothalamus part of the brain, there
is a center called "lipostat" which controls the body mass.
When severe and rapid weight loss is achieved by starvation
diet, the center does not recognise this as normal and therefore
re-programs itself to cause weight gain rapidly once the person
goes off the starvation diet. So the only effective way of losing
weight is slow, self-controlled, and gradual weight loss by
modifying our behavior, and the attitude about eating while
eliminating excess food. Ramadan is a month of self-regulation
and self-training in terms of food intake thereby hopefully,
a permanent change in lipostat reading.
In
Islamic fasting, we are not subjected to a diet of selective
food only (i.e. protein only, fruits only etc.) and carry breakfast,
before dawn is taken and then at sunset, fast is broken with
something sweet (i.e. dates, fruits, juices) to warrant any
hypoglycemia followed by a regular dinner later on.
