In today's society, with the development of the economy and the continuous improvement of people's living standards, the number of obese people is increasing. As is well known, obesity is extremely detrimental to human health. The incidence rates of diseases such as hypertension, coronary heart disease, diabetes, cholecystitis, and obesity - related cardiopulmonary insufficiency syndrome caused by obesity are constantly rising. Obesity has become an important factor endangering human health.

So - called obesity is a chronic metabolic disease. It occurs when there is an excessive intake of energy in the body. The excess energy beyond what the human body consumes is converted into fat and stored in the body. When too much fat accumulates in the body to a harmful degree, this chronic metabolic disease occurs.

There are many reasons for obesity. For example, genetic factors, dietary factors, sitting for long periods, and lack of exercise. Certain endocrine and metabolic diseases can also lead to obesity, among which dietary factors are the most common cause.

Excessive food intake

Consuming too much food will inevitably result in an energy surplus, fat accumulation, and weight gain. The energy density of food is closely related to various energy - producing nutrients in the food. For instance, foods high in fat also have a relatively high energy content. Therefore, attention should be paid to fat intake.

Eating too fast

With a short chewing time and large - volume food, people consume an excessive amount of food in a short period. This way of eating does not easily create a feeling of fullness, causing the amount of food intake to greatly exceed the body's needs and leading to weight gain.

Other abnormal eating behaviors

In addition, over - consuming sweet foods, eating when not hungry, eating while watching TV, eating before going to bed, and eating to relieve stress. These abnormal eating behaviors can also promote the occurrence and development of obesity. At night, the body is mainly dominated by the parasympathetic nervous system, and the food consumed will be stored in the form of fat. Moreover, eating too frequently can also lead to obesity.
