What is obesity and BMI?

People's living standards in today's society have greatly improved compared to decades ago, so many fast foods now have become the most common choice for most young people. However, while pursuing convenience, they ignore the calories of these foods. For example, fried foods contain high calories, so eating these can easily lead to obesity. So we need to understand the impact of obesity on normal life in order to stay away from obesity. So what index does our body reach to be considered obese?

The BMI value was originally designed as a statistical tool for public health research. When we need to know whether obesity is the cause of a disease, we can convert the patient's height and weight into BMI values, and then find out whether there is a linear correlation between the value and the incidence rate. However, with the advancement of technology, the current BMI value is only a reference value. To truly measure whether a patient is obese, body fat percentage is more accurate than BMI, and waist-to-height ratio is better than body fat percentage, but the best way to look at it is to look at visceral fat (if visceral fat is normal, even if the waist circumference is large and the body fat percentage is high, the health risk is not high. Many Japanese sumo wrestlers are fat in this way).

Therefore, the role of BMI has gradually changed from a medical purpose to a slimming indicator for the general public. BMI is the abbreviation of Body Mass Index. BMI means "body mass index" in Chinese and is calculated based on your height and weight. BMI is a universally recognized method for grading obesity, and the World Health Organization (WHO) also uses BMI to define obesity or overweight.

3The BMI index is a number obtained by dividing the weight in kilograms by the square of the height in meters. It is a standard commonly used internationally to measure the degree of fatness and health of the human body. So what are the indicators of obese people? The traditional adult weight standard is generally less than 30. If it exceeds or decreases, it is considered unhealthy.

Therefore, we can use this index to judge whether we are within the normal range, so we can make accurate judgments ourselves. We should also use the correct weight loss method to control our diet as much as possible.

We all know that obesity is a relatively common and ancient metabolic disease group. Simply put, when the body eats more calories than it consumes, the excess calories will be converted into fat and stored in the body. If it exceeds the normal range, this disease will occur.

Obesity is not only extremely harmful to the human body, but also has a certain impact on life. For example, many girls who love beauty cannot wear many beautiful clothes if they are fat, and it will also cause other problems. However, the BMI index is not suitable for everyone. For example, it cannot be used for people under the age of 18 or athletes who are doing weight training. Also, this index is not suitable for breastfeeding women or the elderly.
