Excess body fat increase the workload of the body frame, heart and lungs
Hypertension
Diabetes
High Cholesterol
Atherosclerosis

Sedentary Lifestyle
Poor food habits
Hereditary plays a role, however; the link between generations is unclear

Underweight- 10% or more below the normal weight



Has little body fat as an energy reserve
Less nutrients that the body stores
Increase in health problems; harder to fight off infection
Diets and Eating Disorders

 Fad Diet- is an approach to weight control
that is popular for a short time.


Ex. Grapefruit or the cabbage soup diets

Fasting- not replenishing the body’s nutrients can
be dangerous. Without food, the body starts to
use its own muscle tissue as an energy source.
Liquid Protein Diet- high protein, low carb liquid
diets can have serious side effects; consult doctor
before using this as your only form of weight
loss.
Diet Pills- burn, block, or flush the fat;
researchers have yet to find a pill that can do this
safely. May help in suppressing energy, but can
have other serious side effects.

Extremely low caloric intake; Obsession with exercising;
Emotional problems; Unnatural interest in food; Unrealistic
or distorted sense of body image; Denial of an eating
problem
Most are in their teens or twenties

Quickly eats large amounts of food followed by selfinduced vomiting or purging through abuse of laxatives
Trying to obtain the “perfect figure”
Often very secretive
Vomiting and diarrhea can lead to dehydration; Kidney
damage; Irregular heartbeat; Vomiting erodes tooth
enamel; Tooth decay; Damages tissues in the stomach,
esophagus, and mouth; Nutrient deficiencies can occur
from laxatives not allowing digestion or absorption;
Laxatives can also damage composition of blood
