I believe that many people have such doubts: what kind of talent needs to lose weight?
In fact, in medicine, there are two measures for whether you need to lose weight, one is BMI (body mass index or body mass index), and the other is waist circumference.
01
How is BMI calculated?
BMI, or body mass index, is currently internationally used as a measurement method to determine whether an individual's weight is within the normal range.
The calculation formula is as follows:
(1) Requirements for measuring weight:
We should try to measure in the morning, empty urine, take off the clothes as much as possible, stand barefoot on the scale, and measure the net weight in the fasting state.
Weight values should be in kilograms.
(2) Requirements for measuring height:
Use a clear height for height. When measuring height, take off your shoes, stand straight, look ahead and measure it, so that you can get your net height.
Height values should be in meters.
After completing the BMI calculation, determine whether the BMI is normal according to the interval range in the following table:
Take a girl with a height of 1.6m as an example, her normal weight range should be between 47.36-61.44kg.
If it is less than 47.36kg, it is underweight, indicating that she is too thin;
If it is higher than 61.44kg, it means that you are overweight, and if it is higher than 71.68kg, it is obese.
Pick up the calculator and calculate, you can know your level, and whether you need to lose weight will have the answer.
Generally, people who exceed the normal value are recommended to lose weight, if they are underweight, do not lose any more, otherwise it is likely to affect the body's immunity, and osteoporosis may occur.
Therefore, it is recommended that people who love beauty must lose weight.
02
What is the normal value of waist circumference?
Some people, even if their weight is within the normal range, but the waist is relatively thick, such people need to lose weight.
In general, the waist circumference should be less than 90cm for men and less than 85cm for women.
If this value is exceeded, there is centripetal obesity, or central obesity.
In this type of person, fat will accumulate too much in the abdomen, often forming an "apple-shaped" body. The risk of chronic diseases, such as metabolic syndrome and diabetes, is also higher than the general population.
And these people sometimes tend to ignore abnormalities in waist circumference because they are not high, so they should be paid more attention.
When the waist circumference of women exceeds 80cm and men exceed 85cm, it should be noticed.
Remind you that when we judge whether we need to lose weight, we should not only look at whether our weight is normal, but also combine our waist circumference for comprehensive judgment.
03
Can I lose only one part to lose weight?
For some girls who love beauty, in the process of losing weight, they will be surprised to find that the parts you least want to lose may be lost the fastest, such as the chest.
Maybe the flesh on the face has not yet fallen, the flesh on the waist has not lost much, and the chest has "become smaller".
Because in the process of weight loss, such as increasing energy consumption through exercise, the fat of the whole body will be reduced together, so simple local weight loss, such as slimming the waist, legs, face, etc., is often difficult to achieve.

If you really see that someone else just has a smaller face and thinner legs, then she is likely to have achieved it with the help of some plastic surgery, liposuction and other means.
04
People with diabetes and high blood pressure lose weight
What should I pay attention to?
People with diabetes or high blood pressure are usually also overweight and obese. So how should these people lose weight?
For diabetics, it is generally desirable to lose 5%-10% of their body weight as soon as possible, which can effectively relieve insulin resistance, and blood sugar may slowly drop.
But weight loss should also pay attention to moderation, ensure three meals, do not eat too little in order to control weight.
When exercising, you should also pay attention to preparing small snacks such as sugar and biscuits at any time to avoid hypoglycemia.
When choosing an exercise method, you should also choose a suitable exercise that is gentle and does not increase the rise and fall of blood sugar, and you should also choose loose and comfortable sportswear and shoes.
For patients with high blood pressure, when controlling weight loss through exercise, it is necessary to pay attention to avoid exercising in extreme weather such as heat and cold.
Especially in the cold winter, if you go out to exercise on an empty stomach, you are likely to have a stroke due to sudden vascular contraction.
In addition, when blood pressure is not well controlled, some muscle-building resistance exercises, such as planks, squatting against the wall, etc., should also be avoided as much as possible, and do what you can when exercising.
It should also be noted that exercise is contraindicated during some antihypertensive drugs, so it is recommended to consult a professional doctor or pharmacist before taking medication and exercise.
