"Overweight" is defined as an excess amount of body
weight, including muscle and bone as well as body fat. "Obesity"
is defined as an excess amount of body fat.
Seriously Overweight May Not Mean Obesity
Although most people WILL be obese if they are seriously overweight,
there are exceptions. For instance, the body weight of muscular athletes
is likely to exceed normal weight levels considerably. But the amount
of body fat they have may be less than normal. So while they are overweight,
they won't be obese.
Obesity and Health
A "healthy weight" is simply a weight RANGE that is statistically
related to good health. To say someone is overweight or obese means
that their weight falls into a weight category that is associated with
higher risk of (e.g.) heart disease and hypertension.
Obesity and Healthy Weight
Doctors and health care experts assess healthy weight in three ways.
- By reference to the Body Mass Index (BMI)
The BMI formula is: Weight (pounds) x 704.5 divided by Height (inches)
squared.
A BMI of less than 19 is underweight.
A BMI of 19-24.9 denotes normal weight.
A BMI of 25-29.9 is overweight.
A BMI of 30+ denotes obesity.
- By measuring waist size
Women: Waist size of 35"+ together with BMI of 25+ denotes unhealthy
weight.
Men: Waist size of 40"+ together with BMI of 25+ denotes unhealthy
weight.
- By examining other weight related risk factors
These include:
- Fat distribution
- High blood pressure
- High cholesterol
- High blood sugar
- Arthritis in knees/hips
- Breathing problems
- Family history of obesity/ weight related disease
- Poor lifestyle - smoking, bad eating habits, lack of exercise

Obesity Chart Readings
If you are close to the obesity point for your height, you should definitely
consider losing weight, especially if your weight is on the rise. As
a first step, please consult your doctor.
Fat Acceptance versus Obesity and Ill-Health
Being seriously overweight is not a crime, a sin, or a sign of social
inferiority. It is a physical condition which carries a number of health
risks. You are strongly advised not to accept these risks and instead
to consult your doctor.
Consequences of Obesity
In general, the more you exceed your obesity point, the greater the
health risk. In addition, the higher your proportion of fat to muscle,
the greater the risk.
Waist to Hip Ratio and Fat Distribution
If you divide your waist measurement by your hip measurement you can
find out your waist-to-hip ratio. If it is over 0.8 in a woman or 0.95
in a man there is a higher risk of weight-related health problems due
to unhealthy fat distribution.
Fat Distribution, Intra-Abdominal Fat and Obesity
Recent evidence suggests that WHERE you carry body fat is almost as
important as HOW MUCH fat you have. If you are obese and carry excess
fat around your middle (intra-abdominal fat), your risk of ill-health
is significantly greater than if this fat was on your lower half.
Obesity and Health Problems
Being obese significantly increases your risk of the following:
- Higher blood pressure
- Hardening of the arteries
- Heart attacks
- Varicose veins
- Strokes
- Stomach problems
- Gall bladder problems
- Colon cancer
- Hemorrhoids
- Bladder problems
- Kidney stones
- Prostate cancer
- Movement problems
- Bone & joint problems
- Psychological problems
Causes of Obesity
What causes obesity is not yet fully understood. Hereditary factors
(especially on the mother's side), hormones, domestic environment, eating
habits and general lifestyle all play a part. See also Causes
of Obesity
Solutions for Obesity
Advances in genetic research may yet provide a new generation of drugs
to combat obesity. Bariatric gastrointestinal surgery also has a part
to play. However, it is most unlikely that drugs or surgery alone will
solve the problem. For the foreseeable future, healthy diet and exercise
will continue to be an essential part of any treatment program.
A Practical Approach to Obesity
1. Be positive
You can't change your genetic makeup, or your hormones. But you can
change what you eat and how active you are. Many people with severe
obesity have transformed themselves by making sensible eating and exercise
a priority. You may be obese today, but you don't have to stay obese.
2. Seek help
Your first step is to seek professional help. Consult your doctor and
ask him/her to recommend a suitable program and/or support group. Enlist
the help of family and friends. Remember: no matter how good the program,
having a supportive person in the background will always improve your
chances of success.
3. Learn about food
The less you know about food, the more difficult it is for you to eat
properly. So make an effort to find out all you can about healthy foods
and healthy eating. Don't rely on others to tell you all the answers.
