1. Genetic factors: Adolescent obesity is closely related to parental inheritance. When parents inherit their children's physique, it is not a single genetic factor that determines their children's physique, but a variety of genetic factors. If one parent is obese, the probability of the child being obese is 40%. If both parents are obese, the probability of children being obese will rise to 70% ~ 80%.

2. Psychological factors: In order to alleviate emotional distress and emotional instability, many people also take eating as an outlet, leading to overeating and obesity.

3. Overnutrition: unreasonable food structure, frequent consumption of high-calorie, high-fat, high-protein and low-fiber foods, love to use fried foods and less steamed foods, leading to obesity.

4. Eat too fast: Eating too fast will not only lead to obesity, but also lead to indigestion and stomachache.

5. Insufficient exercise: Children can't eat and consume less energy, which will lead to excess nutrition and energy and lead to obesity.

6. Skip breakfast: Breakfast is very important for teenagers. Within eight hours after breakfast, the body fat will burn faster. If this first meal is omitted, the metabolism of the whole day will be destroyed, and the consequences can be imagined.

The harm of adolescent obesity;

1. Adolescent obesity first manifests as weight gain and a large amount of fat deposition, which makes the body burden and oxygen consumption too large. Obese children consume more oxygen than normal people, which makes them bulky, slow in movement and poor in mobility. Many obese teenagers are often accompanied by flat feet, knee flexion, lower limb flexion, spinal column and intervertebral cartilage injury.

2. Obese children are prone to hypertension, dyslipidemia and abnormal glucose metabolism. In severe cases, they can manifest as type 2 diabetes, thus accelerating the formation of arteriosclerosis and advancing the onset of cardiovascular and cerebrovascular diseases in adulthood.

3. Obesity affects intellectual development. Too much phenylalanine in food often leads to the lack of aminotransferase, which leads to the accumulation of a large number of amino acids in brain cells, forming a fat brain, affecting the activities of brain cells, and leading to intelligence lag behind peers. It is also because obese teenagers have too much fat in their bodies, their oxygen consumption is 30%-40% higher than that of normal people, and their oxygen intake is insufficient, which is manifested as listlessness, fatigue, drowsiness and difficulty in concentration, which affects their learning efficiency and leads to a decline in their grades.

4. Obese children are prone to dyspnea, pneumonia, bronchitis and even severe sleep apnea syndrome. After falling asleep, the breathing interval is prolonged, leading to hypoxia, drowsiness during the day and depression.

Attention: Adolescent obesity is a very serious problem, which does great harm to body and mind. It is imperative to lose weight.
