If you are over
weight, it is indeed recommended to lose that extra from your
body. This is must for physical and psychological wellbeing.

the body which gives a feeling of weight loss. But this has
serious effects on health. Water loss from body is not weight
loss. Another serious mistake is to try a drastic weight loss
say for example 15 kg in 40 days. This has major side effects
as body is not able handle such sudden change and body organs
get affected resulting in many chronic diseases. Various nutritional
deficiencies can also result if diet is severely restricted
without giving consideration to necessary body requirements.
This can also result in hormonal and psychological disbalance.
Medically recommended weight loss is 0.5 kg – 1 kg per week or 2 – 4
kg a month. Your weight loss program must answer following
questions :
- What am I losing - fat or water ?
- How much I need to lose ?
- How am I going to lose this ?
- In what duration I will lose this ?
- Will this program affect my health negatively or positively ?
- How will this avoid nutritional deficiency ?
- Are there some hidden / unexplained products or drugs or methods ?
- How will I maintain what I will lose ?

Assessment of Obesity
There are several methods to assess over weight and obesity states. Some are :
-
Height Weight Range : These are easy to use height weight charts for both males and females. It gives a range of recommended body weight. Some charts gives weight for short, medium and big statures.
-
Brocas Index : According
to Brocas Index the ideal weight of a person is equal to
height of the person in centimeters minus 100. For example
if a person’s eight is 170 cm then the ideal weight
would be 70 kg. Above that is overweight and above 20 % of
ideal weight would be obese.
-
Body Mass Index : In
BMI method weight in kg is divided by height ² (in meters)
For example if a person is 92 kg in weight and has a height of 169 cm then the BMI would be 92 / 1.69 x 1.69 = 32.21
BMI is graded as follows
BMI is graded as follows
Less than 25 - Not Obese
25 – 29.9 – Grade I Obesity
30 – 40 - Grade II Obesity
Above 40 Grade III Obesity

-
Skin Fold Test : In
this method subcutaneous fat (under the skin) is measured
using skin fold calipers. The various sites of measurement
are – at
triceps, abdomen, above hip, subscapular upper back, bicep
mid arm etc. For example anything above than 35 cm (females)
and 40 cm (males) at waist is indicator of over weight.
Body fat in %age can be calculated as follows :
| Skin fold in mm |
|
% age of total body fat |
| 15 - 45 mm |
|
8 – 22 % |
| 46 – 75 mm |
|
23 – 30 % |
| 76 – 150 mm |
|
31 – 40 % |
| Normal body fat |
|
upto 22 % males,upto 30 % females |
| Grade I Obesity |
|
upto 40 % fat |
| Grade II Obesity |
|
upto 45 % fat |
Estimation of weight Loss
Estimation of weight Loss
Excess fat is deposited in body as adipose tissue. This adipose
tissue consists of 75 % fat, 23 % water with small amount
of proteins & minerals. Each kg of adipose tissue contains
7700 kcal. This means to lose one kg of this adipose tissue
either one need to burn 7700 kcal by exercise or take a
diet deficient by 7700 kcal over a period of time. Lowest
recommended calories for females is 1200 and for males
1500. Ideal body weight reduction is 0.5 kg - 1 kg per
week.
Weight Management Options
-
Energy Balance : The basic rule of weight loss is to create a negative energy balance i.e. to take less calories than what will maintain weight and burn some. But this should not be done at the cost of depriving body its basic nutritional requirement.
-
Diet : Dieting
is not starvation. Weight reducing diet must be carefully
planned. A diet with 500 – 1000 calories less than daily calorie recommendation is ideal for safe weight loss. It must provide adequate proteins, vitamins and minerals. Lowest recommended calories for females is 1200 and for males 1500. A simple way to calculate calories is current weight x 24 – 500. If your current weight is 85 kg then a diet of 85 x 24 – 500
= 1540 calories would be good. Diet must contain less
fat and more fibres. Food with high glycaemic index
must be avoided. One must be consistent in eating habits
avoiding erratic patterns. Avoid soft drinks, sweets,
cakes, candies, fried food, cream, butter, alcohol,
fruits like grapes, dried fruits, refined carbohydrates
etc. Take whole grains, leafy vegetables, fruits like
apples, salad etc.
-
Exercise : Exercises are must for safe and lasting weight loss. These help in burning calories and improve body metabolism. Low intensity sustained exercises like aerobic exercises are most suitable. To be more effective they must be done under trained professional. Brisk walking, jogging, swimming, cycling are also helpful.

Lifestyle : Develop a healthy lifestyle. Improve your awareness about weight metabolism, food, exercise etc. Having organized life, low stress and positive relationships all help in better weight management. ( See Lifestyle Management)
-
Medical treatment : Diseases which causes obesity must be thoroughly investigated and treated. Conditions like hypothyroidism, hypogonadism, cushing syndrome causes obesity which will be difficult to manage unless these conditions are well treated. Sub clinical hypothyroidism is the cause of obesity in many people which remains undiagnosed.
-
Drugs and Surgery : There
are some medical options available for weight management
like drugs and surgery. But these must be reserved
only for very specific conditions to be decided by
appropriate doctors. They have their own complications
and side effects so must not be used as ‘easy’ way
of weight management.

during and after weight loss. It improves will power
and self esteem which helps in weight management.

homeopathy is useful aid in weight management. Homeopathy
improves body functions & metabolism. It can
help in normalizing appetite, removing food cravings,
correcting psychological disorders like bulimia etc.

major barrier in weight management is negative attitude & behavior. Lifestyle, eating habits, exercise and many emotional conditions associated with obesity has attitude and behavior in background.
