Obesity and its treatment

The definition of an obese person is a person who has excess fatty tissue and a body mass index (BMI) value above 30. BMI is an indicator that measures weight compared to height.

Excess adipose tissue may have severe health consequences such as diabetes, high blood pressure and high levels of lipids in the blood.

Obesity is one of the most common medical conditions in Western society today, and one of the most difficult to treat and treat.  

Relatively little progress has been made in treating obesity (except for lifestyle changes), but much information has been collected regarding the medical consequences of obesity.

Causes and risk factors for obesity until recently, obesity was associated with a sedentary lifestyle and a persistent excess consumption of calories.  

But today, it is known that these causes of obesity are important, but there are also various genetic factors that play a role in the occurrence of obesity.

As evidence of this, in adoptive children we see a pattern of obesity that is more similar to that of their biological parents than we see in their adoptive parents.  

Research with identical twins has also shown that there is a greater influence of genetic factors on BMI than the influence of environmental factors on it.

The estimate is that between 40% - 70% of obesity can be attributed to various genetic factors, not environmental or lifestyle factors.

As research on mice showed, the presence of 5 genes related to appetite, these genes are the ones that lead to obesity.  

These genes are also present in humans. One of the main genetic factors in obesity is the hormone leptin.

Today, obesity is believed to be a combination of certain genes and not just the result of a defect in one gene.

The increase in obesity in the past decades is mainly due to environmental influences such as lifestyle and dietary habits.

Obesity diagnosis :

As mentioned earlier, obesity is defined as excess adipose tissue.  
Accurately measuring the amount of body fat is complex and needs professional evaluation. 
However, by doing a simple physical examination, it is possible to easily detect the presence of excess fat.  
Body mass index (BMI) provides a relatively good estimate of the amount of adipose tissue (in people who are not very muscular, such as professional bodybuilders).  
BMI is calculated by dividing weight in kilograms by the square of height in meters.

Obesity and its treatment

Indication of BMI values:

 > 18.5-24.9  A normal weight.
 > 25-29.9  Overweight.
 > 30-34.9  Grade 1 obesity.
 > 35-39.9  Grade 2 obesity.
 > Over 40 means obese.

Obesity treatment :

Different diet techniques can be followed, which leads to weight loss and excess fatty tissue.  
Studies have shown that only 20% of patients, are able to treat and remove 6 kg of their weight, and maintain the new weight for two years.

Dietary instructions for patients, for the treatment of obesity are similar to ordinary people:

1- Excessive intake of unprocessed food that is given in the diet.
2- Limit consumption of fat, sugar and alcohol.
3- Eat foods rich in fiber.

There was not, according to research, a significant and healthy preference for one method of treating obesity over another method.

However, there is great importance in educating patients for the treatment of obesity, regarding how to plan early the daily menu, and record the meals eaten. Behavioral education in the treatment of obesity is the cornerstone on the way to lose weight in a correct manner.

Exercising is necessary to maintain weight loss and treat obesity in the long term. Physical activity causes an increase in the consumption of calories in the body.

It is important to point out and emphasize, that exercise alone leads to a small weight loss. The main advantage of exercise is that it helps maintain weight loss over time. Today, it is recommended to engage in moderate-strenuous physical activity for an hour a day.
