To lose weight one must expend
more calories than is consumed.
To gain weight excess consumption
of sufficient calories is all that is required.

by the DGCA for pilot use.

Maintaining ideal weight is best achieved with diet and activity
combined; increasing activity while decreasing food intake.
Maintaining your ideal weight reduces the risk for many diseases and
may prevent premature death.
HOW DO I DETERMINE
MY IDEAL WEIGHT?
(1) Measure your
waist circumference.
Excessive body fat
in your waist area increases your risk for many health problems.The waist circumference should be measured just above the navel.
A high-risk waistline is defined as more than 35 inches (88 cm) for
women, and more than 40 inches (102 cm) for men.
(2) Calculate your
Body Mass Index (BMI).
The body mass index
is a formula to assess a person's body weight relative to height.
It's a useful, indirect measure of body composition, because it
correlates highly with body fat in most people. Weight in kilograms
is divided by height in meters squared (kg/m2). In studies by
the National Center for Health Statistics,
- BMI values
less than 18.5 are considered underweight.
- BMI values
from 18.5 to 24.9 are healthy.
- Overweight
is defined as a body mass index of 25.0 to less than 30.0.
A BMI of approximately 25 kg/m2 corresponds to about
10 percent over ideal body weight. People with BMI's in this
range have a moderate risk of heart and blood vessel
disease.
- Obesity is
defined as a BMI of 30.0 or greater (based on criteria of
the World Health Organization). People with BMI's of 30 or more
are at high risk of cardiovascular disease.
- Extreme
obesity is defined as a BMI of 40 or greater.
Most highly fit
people have a high BMI score but very little body fat. For them the
waist circumference, the skin-fold or fat-fold measurements, or more
direct methods of measuring body fat may be more useful measures.
Ideal Body Weight - CALCULATING YOUR
Body Mass Index
To calculate
your exact BMI number, multiply your weight in , divide
by your height in meters, then divide again by your height in
meters.
