Obesity is a major health issue
in the West because people eat large amounts and get little physical exercise.
Nowadays, in cities especially, people are adopting a sedentary, stressful life.
Over half the population of some industrialised countries is overweight, leading
to increased risk of high blood pressure, diabetes, high cholesterol and
triglycerides, all factors that increase the risk of cardiovascular diseases.
Obesity or overweight is
when energy reserves, primarily in the form of fat, are excessive. It occurs
when the amount of energy obtained through the diet is greater than the amount
of energy expended. It is corrected by ensuring that energy expenditure
(physical exercise, basal metabolic rate, etc.) is greater than energy
A good weight-reducing diet should:
. provide less energy
than is needed to maintain body weight;
. supply adequate amounts of all
. be acceptable, affordable and palatable.
Olive oil and
Olive oil is a nutrient of
great biological value. Like all other fats and oils it is high in calories (9
Kcal per gram), which could make one think that it would contribute to obesity.
However, experience shows that there is less obesity amongst the Mediterranean
peoples, who consume the most olive oil.
It has been demonstrated that
an olive-oil-rich diet leads to greater and longer-lasting weight loss than a
low-fat diet. It is accepted better because it tastes good and it is a stimulus
to eat vegetables.
