What is the standard for mild obesity?

In daily life, we can see people who are obviously overweight everywhere, but some are only slightly obese, while some are very severely obese. If you have mild obesity, you should lose weight quickly, because mild obesity has many harmful effects. For example, mild obesity can cause vascular dysfunction, such as arteriosclerosis. In addition, mild obesity can also affect a person's appearance. So how is mild obesity judged scientifically?

Standards for mild obesity:

The standard for obesity is based on the body mass index (BMI), which is closely related to body fat. BMI=weight (kg)/[height (m)]2, is a commonly used indicator to determine the degree of obesity. The BMI cut-off point is artificially set, mainly based on statistical data obtained from the population or the increased incidence and mortality rates as body fat increases. Normal value of body mass index: 18.5～23.9kg/m2; overweight value: body mass index>23.9kg/m2; obesity value: body mass index≥28kg/m2.

The World Health Organization recommends the following classification criteria for overweight and obesity in Asians:

Standard weight of children (kg) = age × 2 + 8

Standard adult weight (kg) = height (cm) - 105. If your weight exceeds the standard weight by 20% to 29%, it is called mild obesity; if your weight exceeds the standard weight by 30% to 50%, it is called moderate obesity; and if your weight exceeds the standard weight by 50%, it is called severe obesity.

1. Diet control

A scientific and reasonable diet is the basis for weight control. The basic principles of a weight loss diet are low energy, low fat, moderate high-quality protein, and complex carbohydrates (such as cereals); increasing the proportion of fresh vegetables and fruits in the diet. A low-calorie diet is recommended for weight loss: 1000-1200 kcal/d for women and 1200-1600 kcal/d for men.

2. Increase physical activity and exercise

Oxygen consumption within a few hours after exercise is greater than that at resting levels, indicating that exercise can increase energy metabolism. Energy is mainly provided by burning body fat during exercise, but there is no need to perform strenuous exercise to lose weight.

Obesity is a multifactorial chronic metabolic disease caused by excessive accumulation of body fat that threatens health. A high-fat diet, a sedentary lifestyle and heredity are the main causes of obesity. In the interaction between genes and environmental factors (including dietary factors), environmental factors may be more important. When the human body consumes more calories than it consumes, the excess calories are stored in the body as fat. The amount exceeds normal physiological needs and when it reaches a certain value, it develops into obesity. Among the obese population, mildly obese people account for a large proportion. The assessment criteria for mild obesity are: Obesity degree (%) = [actual weight (kg) - standard weight (kg)] / standard weight (kg) × 100%. Obesity degree exceeding 20% ​​to 30% is called mild obesity.
