What is obesity?
Obesity is a pathological and chronic inflammatory disease of moderate severity. It is characterized by an excessive accumulation of fat in the human body. In addition, obesity increases the risk of serious illnesses such as arterial hypertension, type 2 diabetes, coronary artery disease and cancer.
Nowadays, advances in science and technology have radically changed the way people live. Food, clothing and technology have become more affordable than ever. As a result, people began to devote less time to cook to spend more time on leisure.
Why cook if you can put the bag in the microwave and get a ready meal in 5 minutes, or you can order your favorite dish from the restaurant and in 15 minutes, the delivery guy will bring it to you, still warm and flavored.
This craze for processed and high-calorie foods has put people at high risk of weight gain and obesity. According to the World Health Organization, by 2016, many countries have witnessed the prevalence of obesity among their citizens and the number of obese people worldwide reached 650 million. This figure has tripled since 1975.

- A study by the National Health and Nutrition Examination Survey found that approximately 19.3% of children and adolescents in the United States between the ages of 2 and 19 are obese, including 6.1% who are severely obese.
- In 2016, US health care spending on chronic diseases driven by the risk factor of obesity and overweight accounted for $ 480.7 billion in direct health care costs, with an additional $1.24 trillion in indirect costs.

Genes can determine the level of a person’s predisposition to obesity. However, the disease can manifest itself under the influence of various factors of development, behavior and the environment. For example, malnutrition, smoking, alcohol abuse, illness, stress at work, etc.
Another reason people can become obese is an energy imbalance caused by consuming more calories than a person spends for their daily activities. As a result, excess energy is stored in the human body in the form of fats. And excess body fat leads to obesity.

Because it is a fast and reliable way to indulge yourself by using different flavors of your favorite dishes.If stressful conditions persist for a long time, it can lead to overeating and excess fat accumulation.
Nowadays, high technology has become an integral part of our life. More and more people can make money from the comfort of their homes, sitting at their laptops and drinking a cup of coffee. Thanks to the advent of computers and smartphones, people can buy food in just a couple of clicks, talk to their friends, who are on the other side of the planet and watch their favorite movies. And this is usually done while lying on your favorite couch.
All this leads people to an imbalance in their natural way of life. Many people have forgotten about the need for physical activity to keep their bodies fit and healthy.
Remember, the less physically active you are, the fewer calories you burn.
The lifestyle and habits of a person are largely determined by many different factors, including the social environment of a person, the traditions of his family and personal goals. All this also affects the culture of individual nutrition and the level of physical activity.

If, for example, a family has a low income or lives in a not very prosperous area with limited access to sports grounds and supermarkets. It may affect a child’s ability to lead a healthy lifestyle and receive healthy, balanced meals. Obesity can be a side effect of this phenomenon caused by excessive fast food consumption and decreased physical activity.

Health problems associated with obesity
Obesity is a serious disease that can lead to various complications if the necessary measures are not taken in time to treat and prevent it. Obesity is often associated with several health complications that can be life-threatening:

Healthy diet plan
One of the reasons a person’s body accumulates a lot of fat is because a person consumes more calories than they need to keep their body active.
Therefore, one of the methods of treating and preventing obesity is a properly formulated diet. Typically, such a diet should eliminate high-calorie and hard-to-digest foods high in trans fats and sugars from your diet.
For example, you can use a low-carb diet such as the ketogenic diet or the Atkins diet. Low-carb diets are all about limiting the number of carbohydrates you eat. It should help your body switch to a special state called ketosis. In this state, the body begins to process fats into special substances called ketones. It allows the body to switch to using fat as the primary source of energy for the body.
You should consult with your doctor or nutritionist to help you plan the correct nutritional diet.
Medicines are another way to treat obesity. They are usually used as an addition to a diet and exercise plan, or in extreme cases when all other things do not help. It is also worth remembering that medications have many side effects that can lead to new diseases.
If you still want to take medication, consult with your doctor and do not self-medicate.
Bariatric surgery may help when a person is severely obese and other treatments no longer work. The idea behind this surgery is to restrict the size of the stomach or small intestine to reduce the number of calories consumed.
There are several main criteria for determining the need for surgery:
- Your BMI reaches 40 or higher
- Your BMI is in the 35-40 range and you have type 2 diabetes, hypertension, or heart disease.
There are many different types of surgical intervention in such cases and the most basic ones are described below.
- Gastric band – involves putting a silicone ring on the upper part of the stomach and this helps to reduce the stomach size. A smaller stomach fills with food more quickly and a feeling of fullness appears.
- Gastric bypass – The surgeon makes the stomach smaller by dividing it into the upper and lower parts with staples. Then the small intestine is attached to the top. As a result, the body absorbs fewer calories.
- Sleeve gastrectomy – the volume of the stomach is reduced by removing part of it, and as a result, you feel satiety eating less food
Hormone treatment can be another way to treat obesity. Scientists in 2014 have noticed that the beneficial effect of bariatric surgery is associated with changes in intestinal hormones. Hormones, in turn, are responsible for the feeling of hunger, the rate of absorption of nutrients, etc.
Therefore, at the moment, scientists are actively looking for new methods of influencing intestinal hormones.
