1. Definition and dangers of obesity
Obesity refers to a state in which excess fat accumulates in the body, causing weight to exceed the normal range. According to the standards of the World Health Organization (WHO), obesity is defined as a body mass index (BMI) ≥30. Obesity not only affects appearance, but also causes a variety of health problems, such as cardiovascular disease, diabetes, high blood pressure, etc.
| Obesity level | BMI range | health risks |
|---|---|---|
| normal | 18.5-24.9 | low |
| overweight | 25-29.9 | medium |
| Obesity | ≥30 | high |
2. Causes of Obesity
The formation of obesity is the result of a variety of factors, including the following aspects:
1. Dietary factors
High-calorie, high-fat, and high-sugar diets are one of the main causes of obesity. In recent years, fast food culture has become popular, and the popularity of processed foods has caused people to consume far more calories than their body needs.
| food type | Calories (kcal/100g) | obesity risk |
|---|---|---|
| fast food burger | 250-300 | high |
| Carbonated drinks | 150-200 | high |
| green salad | 50-100 | low |
2. Lack of exercise
The pace of modern life is accelerating. Many people sit in the office or at home for long periods of time and lack enough exercise. Insufficient exercise will lead to reduced calorie consumption and fat accumulation.
| exercise type | Calorie consumption (kcal/hour) | weight loss effect |
|---|---|---|
| Jogging | 400-500 | high |
| swimming | 300-400 | in |
| take a walk | 200-300 | low |
3. Genetic factors
Research shows that obesity has a certain genetic predisposition. If one or both parents are obese, the probability of their children becoming obese increases significantly.
| genetic status | Probability of children being obese |
|---|---|
| Both parents are obese | 70%-80% |
| One parent is obese | 40%-50% |
| Neither parent is obese | 10%-20% |
4. Psychological factors
Psychological problems such as stress and anxiety may also lead to obesity. Many people consume too many calories by overeating to relieve their mood.
| mental state | obesity risk |
|---|---|
| chronic stress | high |
| anxiety | in |
| depression | high |
3. How to prevent and treat obesity
The prevention and treatment of obesity require comprehensive strategies, including adjusting diet, increasing exercise, and improving mental state.
1. Healthy eating
Reduce the intake of high-calorie, high-fat foods and increase the proportion of vegetables, fruits and whole grains.
2. Regular exercise
Do at least 150 minutes of moderate-intensity exercise every week, such as brisk walking, swimming, etc.
3. Psychological adjustment
Learn to relieve stress through healthy methods, such as meditation, yoga, etc.
4. Medical intervention
For severely obese people, drug or surgical treatment can be carried out under the guidance of a doctor.
Conclusion
The formation of obesity is the result of multiple factors and requires prevention and treatment from many aspects such as diet, exercise, and psychology. Through scientific methods and persistent efforts, the obesity problem can be effectively controlled.
