For starters
•
United States and the rest of the
world.
•
Body mass index (BMI) – a
measure of obesity, based on a
ratio of weight to height.
•
Obesity: Body weight that is more
than 20 percent above the
average for a person of a
particular height.
•
The subjectivity of beauty
conception.
The regulation of hunger:
Biological factors
•
Hypothalamus - an important part of the brain
which monitors glucose levels.
•
Injuries to the lateral and ventromedial
hypothalamus.
•
Weight set point – the particular level of weight
that the body strives to maintain.
•
Metabolism – the rate at which food is converted
to energy and expended by the body.
The regulation of hunger:
Social factors
•
Societal rules and cultural
influences.
•
Eating habits.
•
Preference to particular foods.
•
Operant conditioning – food might
be associated with comfort and
consolation.
The roots of obesity
•
Leptin – the hormone which appears
to be designed to protect the body
against weight loss.
•
Weight-set-point hypothesis.
•
Hypothesis of settling point – eating
habits are influenced by a
combination of our genetic heritage
and the nature of the environment.
Eating disorders:
Anorexia nervosa
•
Anorexia nervosa: A severe
eating disorder in which people
may refuse to eat while denying
that their behavior and
appearance – which can become
skeletonlike – are unusual.
Eating disorders:
Bulimia
•
Bulimia: A disorder in which a
person binges on incredibly large
quantities of food and later may
attempt to purge the food through
vomiting or the use of laxatives.
Loosing weight and staying healthy
1.
There is no easy route to weight
control.
2.
Keep track of what you eat and
what you weight.
3.
Eat “big” foods.
4.
Cut out television.
5.
Exercise.
6.
Decrease the influence of external, social stimuli
on your eating behavior.
7.
Avoid diets.
8.
Maintain good eating habits.
9.
Set reasonable goals.
10. Don’t feel guilty!
Conclusion:
Food is especially important in
people’s lives not only in
biological, but also in social and
emotional standpoints. Eating
disorders would be prevented if
appreciation of food and correct
eating habits are learned in the
early childhood.
