Fifty percent of the population of industrialized countries is overweight or obese. Approximately1.6 billion people are in this situation, and this population is steadily increasing. Three hundred million people are considered obese with a BMI greater than 30. Also the weight gain in youth is steadily increasing and this data is of greatest concern given that the number of adipocytes that we possess is determined in childhood and adolescence and remains relatively constant in adulthood, in the lean as well as in the obese with stabilized weight. Some causes have been identified as early dietary imbalances, poor balance between the intake of calories and calories burned, or an adverse socio-economic state, genetic, environmental, etc.. causes.
The contemporary way of life easily lends itself to the influence of advertising, fast food, ready-made without discernment. It then becomes more and more evident that nutritional health education, in a broad sense, must take a prominent place in education. For many years we have considered fat as a more or less inert storage depot. We now know that this is an really live organ, that unfortunately affects the brain, kidneys, the heart, etc.. Fat interacts with the entire PNEI system and can contribute significantly to our ruin. According to the NHANES, 78% of men and 68% of women older than 60 years are overweight or obese (BMI ≥ 25 kg / sqm). This represents the highest prevalence of all age groups. The risks of morbidity and mortality have greatly increased, among these:
• hyperinsulinism and glucose intolerance
• neurodegenerative diseases
• respiratory failure
• orthopedic issues
• metabolic syndrome and type 2 diabetes
• not to mention rheumatology and cardiovascular disease
• non-alcoholic liver overload (persistent side effects related to overweight and obesity).
There are different types of fat: brown fat, good fat, around the shoulders; and sex-linked subcutaneous fat around the hips for women; or abdominal fat, very rapidly harmful in quantity, linked to inflammatory diseases.
Women naturally mobilize fat with more difficulty than men because they have less testosterone, and especially because their fat cells are metabolized much more slowly than men, 3 to 7 times less. But a slight excess of fat is necessary for women as a reserve tissue in pregnancy. On the other hand, fat also normally increases a bit after menopause; in fact, women secrete estrogen, which would partially compensate the secretion of estrogen by the ovaries.
