Obesity is defined by the World Health Organization (WHO-WHO) as “abnormal or excessive fat accumulation in the body that will impair health”. We can state that obesity, which comes from the Latin word ‘obesus’, has been accepted as an element of reputation for many years in the historical process. Overweight, sometimes described as an abnormal condition, began to be considered disrepute in the following years. The fact that 1.9 billion people around the world are overweight reveals how common this problem is. 300 million of these people are considered as medical cases.

What are the causes of obesity?

The most common cause of obesity is lack of movement and eating disorders. Since more calories are taken with nutrition, obesity appears. Because excess calories begin to accumulate in the body as fat. The widespread use of fast food consumption in recent years is also among the causes of obesity. Studies show that stop smoking is one of the causes of obesity for some people. There are many different studies on this subject, but we can state that this is the general opinion.

Weight gain may also occur if women do not pay attention to nutrition during pregnancy. Sometimes medical problems can cause weight gain. Of course, we should not forget the age factor in this regard. Because as age progresses, weight gain also increases. The socio-economic status of the people is extremely effective on their eating habits. Therefore, it should be noted that the socio-economic situation is very closely related to weight gain.  One of the most common causes of obesity is genetic factors. At this point, it is necessary to mention some drugs such as anti-depressants that are used for a long time. Because it is known that some drugs can cause obesity. Finally, it should be pointed out that after frequent diets, weight can be gained again.

First of all, one should not confuse “overweight” with “obesity”. Although these two concepts are used interchangeably in everyday life, they are actually different from each other.

Technology has developed over time and people started to eat at night, especially with the availability of electricity.

Therefore, there was an increase in non-genetic obesity. In the next stage, convenience foods and fast food entered our lives and obesity became a much more common problem. In the 20th century, although varying by country, obesity rates reached 40%. Obesity-related deaths began to occur.
