The Role Of Diet In ObesityObesity is defined as an increase in body fat. This increase translates into an increase in weight and although not all weight gain is due to an increase of adipose tissue in medical practice the concept of obesity is related to body weight.

How To Classified?

To classify obesity have been used many techniques, both direct and indirect. However, in clinical practice, the degree of obesity is determined by body mass index) BMI), as this is the one that best correlates with the degree of body fat. This index relates the weight in kilos and height in meters squared:

BMI (weight in kg / height in m2)

Following the criteria of the Spanish Society for the Study of Obesity (SEEDO) and the recommendations of the World Health Organization (WHO) accepted the classification of different degrees of obesity as body mass index of adults between 20-69 years

What factors affect the classification of obesity?

Other key issues when evaluating and classifying obesity include: the age of onset of obesity, the relationship with the patient’s usual diet, lifestyle (sedentary lifestyle), administration of drugs that promote weight gain, the psychological status and patient’s emotional response, the presence or absence of associated hormonal and metabolic disorders, family history of obesity, family history of cardiovascular and metabolic disease.

What is the relationship between waist / hip ratio and obesity?

In recent years it has become very important NDE the distribution of body fat, so that the deposit of fat in the abdominal region (android distribution) has been linked to severe metabolic disorders like diabetes mellitus or dyslipidemia and cardiovascular disease. For these reasons, the waist / hip ratio is considered a fundamental aspect in the assessment of obesity and its complications. Individuals with waist-hip ratio greater than 1, in men and 0.9 in women, defined an android fat distribution and related metabolic disorders and referred cardiovascualres. By contrast, men with a waist-hip ratio less than 1 and less than 0.9 women have a gynoid distribution of body fat, which is associated with alterations in mechanical and morbidity of osteoarticular and vascular disorders in the limbs venous inferred.

Some times in life more vulnerable to developing obesity to be taken into account: the prenatal period and lactation period of 5-7 years (rebound fat mass), adolescence (autonomy and change of eating habits), adult Young (decreased physical activity), pregnancy (excessive weight gain), menopause (hormonal changes), the latest period of adult life (again, decreased physical activity).

What is the role of diet in obesity?

A proper diet is the cornerstone to avoid obesity. Therefore, the main objective is that both the general population as obese individuals acquire proper eating habits are maintained indefinitely.

The diet should be balanced, both from a quantitative point of view (the amount of calories you should eat) and qualitative (composition of the food we eat).

Foods contain nutrients that provide the energy needed to develop physiological functions essential for the maintenance of life. The measure of that energy is the calorie. The energy content of food is measured in kilocalories (1,000 calories).

When obesity occurs?

The maintenance of body weight is based on the balance between energy intake and total energy expenditure. If you eat more calories than are spent, their accumulate, leading to obesity.
