Today's topic is a off topic. But it is also important for us. So, lets start....
Health is wealth. If anyone is not healthy, he can’t enjoy the
world. Some people don’t have control over their eating. They eat too much. So
, as the result they become unhealthy. Even some people don’t eat what they
need for their nutritive demand. So, we must eat what we need for our nutritive
demand.
But there is a way to know the
exact amount of how much food we need to eat. How much food we need to eat to
be healthy.. We can know how much calories
we need everyday by this process. The process is a type of calculation. The
process is B.M.R (Basal Metabolic Rate)
We all may know what calorie is !
If you don’t know what calorie is then I am giving a short description what it
is.
Calorie(K) is the amount of thermal
energy. We use it to calculate the thermal energy in foods. We are going to
know the amount of food we need to eat by this calorie. 1000calorie = 1
kilocalorie
Now, We are going to describe the
way to calculate our B.M.R.
The theory is-
B.M.R for female = 655 + {9.6xweight(kg)}
+ {1.8xheight(cm)}
- (4.7xage)
B.M.R for Male =666 + {13.7x
weight(kg)} + {5xheight(cm)} - (6.8xage)
Suppose, A woman is 33 years old.
Her weight is 94 kg and height is 165cm.
So, her B.M.R is = 655+(9.6x94)+(1.8x165)-(4.7x33)
=1699.3
Calorie
Physical condition
|
Calorie Standard
|
Not Diligent
|
BMR value x 1.2
|
A little diligent, works 2-3 days a week
|
BMR value x 1.375
|
Diligent, works very hard 2-3 days a week
|
BMR value x 1.55
|
Diligent, works very much (whole week)
|
BMR value x 1.725
|
Excessive Diligent, works very much
|
BMR value x 1.9
|
As an
example, supposing the woman is not diligent and her BMR value is 1699.3, her
Calorie demand is
= (1699.3
x 1.2)
= 2039.16
Means the woman can keep her weight the same taking 2039 Calorie contained
food.
BMR rate depends on age, gender,
food-stuff and body formation. It also depends on our nutritive demand.
BMI (Body Mass Index) is a way to
know you are healthy or not. It depends on Weight & Height. To know your
BMI, There is a theory. The theory is-
BMI = Weight (kg) / Height (cm)
If a boy’s height is 125 cm (1.25
m) and weight is 50 kg then his BMI will be 32.
But how can you know that you are
healthy or not from the BMI. There is a
chart describing the rate’s meaning. The chart is given below-
Rate
|
Description
|
Below
18.5
|
Low weighted, must take certain
food
|
18.5-24.9
|
Healthy
|
25-34.9
|
Excess weight, needs to lose
weight by exercising
|
30-34.9
|
First stage of being fat, should
take appropriate food and exercise.
|
35-39.9
|
Second stage of being fat, should
take enough food and exercise.
|
Above
40
|
Excess fat, probability of death,
must take doctors advice.

So, guys follow this rules and you
will be healthy in scientifical way………
