People who are significantly overweight with an
excessive amount of body on the breasts, belly, arms, bottom,
thighs and even under the chin is a condition called Obesity.
It may be due to over eating or other causes. To check if you
are obese, individuals with a BMI of 25 to 29.9 are considered
overweight, while individuals with a BMI of 30 or more are considered
Overweight refers to increased body weight in relation
to height. However, overweight may or may not be due to increases
in body fat. It may also be due to an increase in lean muscle.
For example, professional athletes may be very lean and muscular,
with very little body fat, yet they may weigh more than others
of the same height. While they may qualify as "overweight"
due to their large muscle mass, they are not necessarily "over
fat," regardless of BMI.
As for obesity, it is defined as an excessively
high amount of body fat or adipose tissue in relation to lean
body mass. The amount of body fat (or adiposity) includes concern
for both the distribution of fat throughout the body and the size
of the adipose tissue deposits. Skinfold measures, waist-to-hip
circumference ratios, or techniques such as ultrasound, computed
tomography, or magnetic resonance imaging can estimate body fat
BMI stands for Body Mass
Index. It is a number that shows
body weight adjusted for height. BMI can be calculated with simple
math using inches and pounds, or meters and kilograms. For adults
aged 20 years or older, BMI falls into one of these categories:
underweight, normal, overweight, or obese.
Body Mass Index calculation using metric with this
BMI = [Weight in Kilograms / (Height) x (Height)]
For example, a person who weighs 99.79 Kilograms
and is 1.905 Meters (190.50 centimeters) tall has a BMI of 27.5.
Body Mass Index calculation using pounds and inches with this
BMI = [Weight in Pounds / (Height in inches) x (Height
in inches)] x 703
For example, a person who weighs 220 pounds and is 6 feet 3 inches
tall has a BMI of 27.5.
Check your BMI against the chart below to determine
your weight status:
18.5 – 24.9
25.0 – 29.9
30.0 and Above
Remember that two people can have the same BMI,
but a different percent body fat. A bodybuilder with a large muscle
mass and a low percent body fat may have the same BMI as a person
who has more body fat because BMI is calculated using weight and
All persons who are obese or overweight should try not to gain
additional weight. In addition, those who are obese or who are
overweight with other risk factors should consider losing weight.
Whatever your BMI, talk to your doctor to see if
you are at an increased risk for disease and if you should lose
weight. Even a small weight loss (just 10% of your current weight)
may help to lower the risk of disease. Physical activity and good
nutrition are key factors in leading a healthy lifestyle and reducing
risk for disease.
There are a variety of factors that play a role in obesity. Behavior,
environment, and genetic factors may have an effect in causing
people to be overweight and obese. Obesity and overweight are
chronic conditions. We discuss some as follows:
· Overweight and obesity result from an energy
imbalance. This involves eating too many calories and not getting
enough physical activity.
· Body weight is the result of genes, metabolism,
behavior, environment, culture, and socioeconomic status.
· Behavior and environment play a large role
causing people to be overweight and obese. These are the greatest
areas for prevention and treatment actions.
Genetics -How do genes
Science shows that genetics plays a role in obesity. Genes can
directly cause obesity in disorders such as Bardet-Biedl syndrome
and Prader-Willi syndrome.
However genes do not always predict future health.
Genes and behavior may both be needed for a person to be overweight.
In some cases multiple genes may increase one’s susceptibility
for obesity and require outside factors; such as abundant food
supply or little physical activity.
People may make decisions based on their environment or community.
For example, a person may choose not to walk to the store or work
because of a lack of time or walk ways. Communities, homes, and
workplaces each shape health decisions. With fewer options for
physical activity and healthy eating, it becomes more difficult
for people to make good choices.
Lacking in activity
Our bodies need calories for daily functions such as breathing,
digestion, and daily activities. Weight gain occurs when calories
consumed exceed this need. Physical activity plays a key role
in energy balance because it uses up calories consumed. The belief
that physical activity is limited to exercise or sports, may keep
people from being active. Another myth is that physical activity
must be vigorous to achieve health benefits.
Physical activity is any bodily movement that results
in an expenditure of energy. Moderate-intensity activities such
as household chores, gardening, and walking can also provide health
benefits. Confidence in one’s ability to be active will
help people make choices to adopt a physically active lifestyle.
Genetics and the environment may increase the risk
of personal weight gain. However, the choices a person makes in
eating and physical activity also contributes to overweight and
obesity. Behavior can increase a person’s risk for gaining
Weight gain is a result of extra calorie consumption, decreasing
calories used (physical activity) or both.
Other Causes - Diseases and
Some illnesses may lead to obesity or weight gain. These
may include Cushing's disease, and polycystic ovary syndrome.
Drugs such as steroids and some antidepressants may also cause
weight gain. A doctor is the best source to tell you whether illnesses,
medications, or psychological factors are contributing to weight
gain or making weight loss hard.
