Narrated Ibn `Umar:
-
Allah's Apostle said, "A believer eats in one intestine (is satisfied with a
little food), and a kafir (unbeliever) or a hypocrite eats in seven intestines
(eats too much
DIAGNOSIS OF
OBESITY

The Difference Between being Overweight and Obesity- How can I Tell?
What is the difference between being overweight and obesity The "overweight"
and "obesity" interchangeably. The two words are not synonymous.
The medical-dictionary definition of obesity describes it as " a bodily
condition marked by excessive generalized deposition and storage of fat." This
means that throughout the body there is an excess of fatty tissue stored beneath
the skin. The key word is Fat.
Weight on the other hand is defined as " a quantity of heaviness " or "relative
heaviness". Overweight, then may be defined as over heaviness.
What constitutes body weight?
-
Your body weight is made up of several components and those such as fat, muscle,
and bone vary according to age, sex and height.
-
What determines the degree of fatness or obesity?
It is the actual amount of "fat" deposited beneath your skin which determines
your degree of fatness or obesity. Doctors often use a simple rule of thumb
which gives them a general idea of the degree of obesity in persons above the
age of twenty-five years. With reference to a standard weight chart, if you are
more than :
-
I.
ideal weight + 20% you are said to have clinical obesity.
-
II.
ideal weight + 40% you are said to have gross obesity.
How does food get converted to fat in the body?
-
Fat stored in the body can be made from any food component - carbohydrates,
proteins or fats. When food is eaten, it travels to the stomach and intestines.
Enzymes break down food into glucose, amino-acids and minute droplets of fats.
The fats travel to the liver and are processed to form fatty acids and glycerol.
From the liver, the fatty-acids enter circulation where they are broken down
further to release energy for immediate use by many organs. Any excess is
reconverted to fatty acids and stored in fat cells under the skin and around the
internal organs.
HOW FAT FORMS
-
Fats stored in the body can be made from any food component (carbohydrates,
proteins or fats). When food is eaten, it travels to the stomach and intestines.
Enzymes breakdown the food into glucose, amino acids and minute droplets of fat.
The fats travel to the liver, where they are processed. From the liver, the fats
enter the circulatory system where they can be used for energy by many organs.
Excess fats will be stored in the fat cells (1). When more energy is needed,
fats are released. If the need continues, the cells will shrink but the nucleus
remains the same (2). The glycerol is converted to glycogen, which is either
broken down at once to release energy or stored in the liver’s glycogen storage
system. When this is full, the glycogen is changed into fat and stored in body
cells, making you over-weight, if a lot is stored there.
What is that makes people fat?
-
Prof. Sir Charles Dodds of the Royal Society of Medicine, conducted the
following experiment :- He took people whose weights had been constant for many
years and persuaded them to eat double or treble their normal amount of food.
They did not put on weight.
He then overfed people whose weights had not remained constant in the past and
found that they became fat.
From Prof. Dodds’ experiment, we learn that two people of the same size, doing
the same work and eating the same food will react quite differently when they
overeat. One will stay the same weight. Why? The answer is that of metabolism.
The first category of people when given extra food responded to over- eating by
increasing their metabolic rate, i.e. the rate of using of the food by the body,
and burnt up the extra food. The second category of people showed no increase in
metabolism, when over-fed, and simply changed the food into fat.
This fact about two people reacting quite differently when they overeat, has
been known to us, and yet this fact never seems to be taken into account or
explained by the various experts who write popular books and articles about
slimming.
Ancient science of Ayurveda on the other hand , was well aware of this
physiological fact, and in their text- book like ‘Bhava Prakash" they mention
certain plants and their products that can successfully and safely combat
obesity.
What exactly is metabolism?
-
Metabolism is the term used to include in one word all the complex chemical
processes within the body which determine the growth and replacement of the body
tissues, the production of body heat and energy necessary for muscular activity
and other vital functions. In a sense then, what lay people call the life
processes of the body, scientists call the meta- bolism.
-
But Doctor, I eat my food in normal quantities, then how do you account for my
problem of obesity ?
The real question that needs answering about obesity is :
What is the cause of the fat man’s failure to use up as much energy as he takes
in as food? It could be that although you only eat normal quantity, some defect
in the way your body deals with food, deflects some of what you eat to your fat
stores and keeps it there instead of letting you use it up for energy.
In other words you have a defect in your metabolism which a person with constant
weight does not have. Too much attention has been paid to the input side of the
energy equation and not enough to the possible causes of defective output. Even
with a low food intake, a person gets fat because his output is small. And this
need not be because of insufficient exercise, but because something is
interfering with the smooth conversion of fuel to energy in his body and
encouraging it’s storage as fat. Which means that something is wrong with his
metabolism. The metabolic rate of every individual is different.
What is metabolic rate? Is there any test to determine it?
-
All individuals are metabolically different. One person’s metabolism may be more
active or less active than another’s. The metabolism, then has a "rate". The
rate may be average, slow, or fast, as the case may be.
Just as you might judge the heat in a kettle by the amount of steam coming out
from its spout, so too scientists have a way of determining the human metabolism
rate.
The amount of carbon dioxide thrown off by the breath keeps pace with the heat
production of the body. A apparatus has actually been devised to measure this
output. A person’s internal heat production can be determined by taking into
account his /her height and approximate skin area in relation to his/her
carbon-dioxide output.
You can take a metabolism test usually twelve hours after you have eaten a light
meal of about 70 degrees F. and when you are at absolute physical and mental
rest. The result of this metabolic test is called the "Basal Metabolism Rate’.
Doctors call it the B.M.R.
You must have seen a fire burning brightly and quickly in a draft. Well, in a
sense, the basal metabolism rate is the draft in which the bodyfires burn -
scientifically, ‘oxidation’ takes place. It is by oxidation that body heat is
produced - that warmth of life, the 98.6 degrees F. temperature that your body
has in health.
The rate of your basal metabolism has much to do with the question of food and
body fat accumulation. Basically, body fat is food, which has not been burned
into heat or energy. Now if food is the fuel source of humanbody heat, and
metabolism the medium that converts food into heat, there must be a definite
relation between basal metabolism rate and fat production - and there is, a
decided one.
A normal metabolism rate helps you greatly to stay just about normal in weight.
A slow metabolism rate makes you tend to put on kilos, and a high metabolism
rate is apt to keep you thin.
But my Doctor says that I have normal metabolism rate,
then why am I fat?
-
To my mind, this is not strange because the basal metabolism rate, is a
comparatively crude measurement of the "total" metabolism. A component of the
total, such as fat metabolism, may be functioning abnormally without affecting
the complete picture, just as an aberration of sugar metabolism in diabetes, is
not reflected in the basal metabolism rate.
-
Doctor could there be any other reason for my obesity other than my metabolism ?
The underlying reason in more than 95 per cent of all cases of obesity, is an
imbalance between energy output and energy intake. That is, the body in carrying
out its functions, does not expend as much energy as it takes in through food
and liquids. This is a disturbance in metabolism, and it shows up in three ways
:-
-
-
1.
The body forms fat at a rate that is faster than normal.
-
2.
The body stores fat at a rate that is faster than normal. Fat formed in the
digestive system quickly reaches the arms, the thighs, in the form of fat
deposits - the deposits that stretch your skin and distort your shape.
-
The body disposes off stored fat at a rate that is slower than normal. This is
why it is so difficult to lose weight from the places you want to lose it. The
body that is forming and storing fat can’t get rid of the fat already stored as
easily as it should. The disturbance in your metabolism therefore works on you
in three ways, all very damaging.
Health HAZARDS OF OBESITY
Why should I reduce?
-
The success of a weight-reducing programme is based on extreme co-operation and
motivation on the part of an obese person. You have to want to reduce.
Anyone who wants to reduce must feel strongly enough about it so that he will
adhere to a reasonable reducing-regimen and adhere to it full time. One cannot
follow it five days a week and hope for results. As you will see my plan for a
Balanced-Nutrient Diet requires certain adjustments in eating habits. Nothing
drastic. Just sensible eating. Perhaps substituting fruits for fried foods as a
snack. But you have to make these re-adjustments rigidly. You have to build up
your will-power. You have to realize that fat is not just a matter of not
looking good or a cosmetic problem. It is a major health problem to millions and
millions of people in every area of life.
According to research studies carried out by the Metropolitan Insurance Company
of America, the death-rate for obese men ranged 75 per cent higher than that of
men of normal weight. For obese women the rate was as much as 61 per cent above
normal.
People 7 to 10 kilos overweight have a death rate 10 per cent higher than
normal. The rate grows proportionately higher with additional kilos. So every
extra kilo you put on increases your chance of dying before your time. If you
are 40 kilos overweight, you have 85 per cent greater chance of dying earlier
than does a person of normal weight.
There is more than glamour in keeping slim. It can be a matter of life and
death.
What will extra kilos do to my blood pressure?
-
In general your blood pressure tends to go up as your weight increases. A survey
on the effects of weight was made on 22,741 officers in the United States Army,
both men and women. It showed that among men and women of every age group, blood
pressure increased steadily in proportion to their body weight. Hypertension,
the medical term for high blood pressure, develops in overweight people two and
a half times as often as it does in people of normal weight.
Fat people have higher blood pressure probably because the extra fat puts a
special burden on the circulatory system; there is more tissue for the blood to
reach. Fat people suffer from arteriosclerosis or hardening of arteries. No one
is quite sure of the reason, but doctors are sure that a relationship between
this disease and obesity exists.
Based on various research studies of blood pressure measurements of 746 men who
worked for Chicago utility company; the United States Department of Health has
concluded :
-
1.
More hypertension ( high blood pressure ) exists among the obese than among the
non-obese.
-
2.
The obese person with high blood pressure experiences a greater risk of coronary
heart disease and heart attacks than the non-obese person with high blood
pressure.
-
3.
Death rates for obese persons with high blood pressure are higher than those for
persons who are only obese and those with high blood pressure, without the
complicating obesity.
-
What is diabetes? How is it related to my obesity?
Diabetes mellitus is today the third major killer of human beings. In India
alone, there are over 15 million persons suffering from the disease and an equal
number who are not even aware of it.
There are several distinct varieties of diabetes. Diabetes affecting young
children called Juvenile Diabetes is usually insulin-dependent type. These
children succumb to their disease if not treated with insulin. Diabetes
affecting most adult, the Maturity Onset Diabetes is usually not insulin
dependent. It is also heartening to note that 95% of all the diabetics in our
country belong to the non-insulin dependent group. They can survive without
insulin. The juvenile diabetic is more often thin than fat, whereas the Maturity
Onset Diabetic is more often fat than thin.
Research studies have shown that eight out of ten persons - the Maturity Onset
Type, are obese when symptoms first appear and that among people who are forty
or over, nine out of ten who are down with diabetes are overweight. Diabetes
often described as a "fat man’s folly" is a reasonable name.
Amongst the non-insulin dependent diabetics, the lean or normal weight patients
are very different from the obese diabetics. The undernourished diabetics often
have marked rise in blood sugar and although not dependent on insulin for their
survival, they often require oral drugs or even insulin to achieve normal sugar
levels. The obese diabetics, in contrast hardly ever require insulin. The
fasting blood sugar is often normal and only the "post" meal blood sugar is
mildly or moderately elevated in the obese diabetics. Experimentally it has been
shown that the obese Maturity Onset Diabetics most often have an abundance of
insulin in their blood. But in the presence of obesity the action of insulin is
blunted and the body fails to use sugar properly. It is fairly easy to achieve a
"cure" for diabetics in this group. Even a modest weight loss causes a distinct
improvement in their diabetes. If the weight loss is maintained , the "cure" of
diabetes is permanent. Although we do not talk in terms of cure in other forms
of diabetes, obesity-related diabetes is indeed curable. Of course we assume
here that the obese patient has lost weight and is able to maintain this weight
loss.
Does too much or too less of a hormone cause obesity or is
it the other way round?
-
Let me explain this with an example.
When certain people are under tension, their system puts out more of an adrenal
gland secretion called hydrocortisone which tends to increase the appetite.
These people are stresseaters. They feel better when they eat. This leads to
overindulgence of food. Result, Obesity.
On the other hand, if a person is overweight, this might alter his body’s
metabolism, so that the adrenal glands tend to be over responsive in stress
situations leading, to increase in appetite, overindulgence of food and
resultant obesity. But the question is, what has led to obesity ? Has increased
amount of hydrocortisone caused obesity or has obesity caused increase in
secretion of hydrocortisone? In short, it is difficult to say, "Which is the
cart and which is the horse?" with regard to over weight and obese individuals.
