1. How to determine various body shapes
The answer is as follows: Height is mainly considered when determining body shape. , weight, BMI, waist and hip circumference and other indicators. Different body types have different judgment standards.
1. Thin type: low weight, BMI less than 18.5, small difference between waist and hip circumference.
2. Standard type: moderate weight, BMI between 18.5-24, reasonable difference between waist and hip circumference.
3. Obese type: overweight, with a BMI greater than 24 and a significantly increased waist circumference.
4. Muscular type: Overweight, with a BMI between 24-28, well-developed muscles, and a relatively coordinated waist-to-hip ratio.
5. Slender type: taller, lighter in weight, with a BMI below 18.5 and a relatively small waist-to-hip ratio.
6. Fat and short type: short in height, overweight, with a BMI above 24, and a relatively small waist-to-hip ratio.
7. Short and fat type: short height, overweight, BMI greater than 28, waist-to-hip ratio is obviously uncoordinated.
RequiredPlease note that the above classification is only a common judgment standard. Different people\’s body shapes are also affected by various factors such as genetics, diet and exercise. Therefore, when judging your body shape, you should make an assessment based on your actual personal situation.
2. What does medium to high weight mean
1. Weight score It is normal, on the low side and on the high side. If a person is overweight, he or she needs to lose weight.
2. People who are overweight will generally have body fat. High blood pressure usually easily leads to obesity, and is easily complicated by hypertension, hyperlipidemia, arteriosclerosis, coronary heart disease, diabetes and other diseases.
3. Unhealthy lifestyles should be corrected in time. You can reduce your body fat rate through a reasonable diet and increased exercise. Or you can eat high-protein foods, such as fish, eggs, etc., and you can also eat high-fiber, high-vitamin foods, such as broccoli, carrots, etc., which can help delay the accumulation of fat in the body. Try not to eat or eat less spicy and exciting food, and at the same time, you should also exercise more regularly, such as skipping rope, running and other sports
3. Age, height and weight, which category do they belong to together
Height<165cm: Height (cm)-105 (male)
②Northerners=(height cm-150)×0.6+50
Moderate obesity:=SW+SW×（ 0.31～0.30)
Severe thinness: =SW-SW×0.20 (and above 0.21)
Severe thinness: =SW-SW×0.20 (and above 0.21)
The standard weight of men (kilograms) = length (cm) – 100
The standard weight of women (kilograms) = length (cm) – 102
p>
Adult: [Height (cm)-100]×0.9=standard weight (kg)
Male: height (cm)-105=standard weight (kg)
Female: height (cm)-100=standard weight (kg)
The above two calculation methods have basically been widely adopted.
In addition, the Academy of Military Science recently introduced a method for calculating the ideal weight of Chinese people:
The ideal weight for northerners = (height cm-150) × 0.6 + 50 (kg)
The ideal weight for southerners = (height cm-150) × 0.6+48 (kg)
This calculation method seems to be more suitable for Chinese people in the north and south.
The simple way to calculate the standard weight of children is:
1 to 6 months : Birth weight (kg) + age in months × 0.6 = standard weight (kg)
7 to 12 months: birth weight (kg) + age in months × 0.5 =Standard weight (kg)
Over 1 year old: 8+age×2=Standard weight (kg)
1. Subtract 100 from your height in centimeters and multiply it by 0.9. The answer you get is your standard weight in kilograms. It is normal to be 10% lower or higher than the standard weight
2. Body mass index = weight (kg) / body height (meters) squared. The normal range is 18.5-22
The results calculated by the two formulas are similar, because they both have a range, and as long as it is within the range, it is considered normal. The quantitative phenomena of all living things have no absolute value, such as hemoglobin value, blood sugar value, weight, height, etc.
4. Height ÷ How to calculate weight squared
Answer: Height divided by weight squared is a person\’s body mass index. The weight unit here is kilograms, and the height unit is meters. For example, a person weighs 50 kilograms and is 170 centimeters tall, which is 1.7 meters. Then, the person\’s body mass index is: 50÷1.7^2=approximately equal to 17.3.
5. How to judge from height and weightIs a person fat or thin
People can be fat or thin. If they are underweight, they are thin, and if they are overweight, they are fat. So what standard is used to measure it? Is it fat or thin? Of course, there must be a reference value. We call this reference value the standard weight. At present, there is no unified standard weight data in our country. There are two commonly used calculation methods:
One is: Adult: (height (cm)-100]*0.9=standard weight (kg )
The other is: Male: height (cm) – 105 = standard weight (kg),
Female: Height (cm) – 100 = standard weight (kg)
The above two calculation methods have basically been widely used.

In addition, the Academy of Military Science also launched a method to calculate the ideal weight of Chinese people:
Ideal weight for northerners Weight (kg) = (Height in centimeters – 150) x 0.6 + 50. The ideal weight for southerners (kg) = (Height in centimeters – 150) x 0.6 + 48. This calculation method seems to be more suitable for the standard weight of Chinese children in the north and south. The simple method for calculation is: 1 to 6 months: birth weight (kg) ten months of age * 0.6 = standard weight (kg); 7 to 12 months: birth weight (kg) ten months of age X 0.5 = standard weight (Kilograms); Over 1 year old: 80 years of age There are differences, and there will be certain changes at different times on the same day. In addition, the geographical location (such as the reason for gravity), the season, the climate, and your own situation will also have a certain impact on your weight, so it is difficult to fully meet the requirements. Standard weight. In other words, it is difficult to express it as a constant value, but it should be a numerical range. We call this numerical range the normal value, which is generally within +-10% of the standard weight. It can be called abnormal weight. If the measured weight exceeds the standard weight, but the excess is less than 20%, it is called overweight; if the measured weight exceeds the standard weight by more than 20%, and the fat percentage (F%) exceeds 30%, it can be diagnosed as overweight. Obesity. Those whose body weight exceeds 30% to 50% of the standard body weight and whose F% exceeds 35% to 45% are called moderate obesity; those who exceed the standard body weight by more than 50% and whose F% exceeds 45% are called severe obesity. /p>
6. Know how to calculate volume based on height and weight
The largest proportion of the human body is water, so Just calculate it according to the density of water, just divide the mass by the density of water 1000kg/m3!
OK, this article ends here, I hope it will be helpful to everyone.
