Improve triglyceride and low density lipoprotein (LDL) cholesterol levels (harmful to health) and reduce high density lipoprotein (HDL) cholesterol levels (beneficial to health). Visceral fat can reduce the body's sensitivity to insulin, which is responsible for maintaining normal blood sugar level and weight. If you resist the island element, research shows that no matter how hard you try, dieting alone may not help you lose weight permanently. Recent studies have shown that excessive visceral fat is an independent risk factor for heart disease. In addition, it will increase your risk of developing diabetes in the future.
Excessive visceral fat will increase the level of C-reactive protein in the body, thus inducing "silentinflammation". Asymptomatic (painless inflammation). It is the root of some chronic diseases, such as heart disease, obesity, diabetes, dementia and cancer.

People in pear shape store fat in their thighs, buttocks and buttocks. Like pears, they are the largest below the waist. These stored fats are called subcutaneous fat. They are the fat under the skin and above the abdominal muscles. Subcutaneous fat metabolism is inactive, and it is basically a repository. They are presented in the form of fat and can be clearly seen. What you can pinch with your fingers is subcutaneous fat. According to a recent report of Oxford University, people with fat in thighs and buttocks (subcutaneous fat) may live longer than those with fat in abdomen (visceral fat prevention), because subcutaneous fat will intercept harmful fat particles and actively secrete beneficial compounds.
These two fats behave very differently in the body. Tim Church, medical director of the Cooper Institute in Dallas, said: "If you put visceral fat in a Petri dish and subcutaneous fat in a Petri dish and stimulate them, visceral fat will produce more inflammatory molecules, which will increase a person's risk of heart disease and diabetes."
? Detecting obesity
Now many experts are suggesting that it is time to forget to lose weight and pay attention to how to reduce visceral fat, especially waist and abdomen fat, in order to alleviate insulin resistance.
Petri dish is a kind of glassware designed by German R, J, d. Petr. It is a round shallow dish made of thin glass with a lid. It has various sizes and specifications and is used to cultivate microorganisms or animal and plant tissues in biological experiments. Translator's note
? Compared with people who are overweight but have a small waist or stomach, people who are overweight but have a big stomach are more likely to suffer from weight-related diseases and have higher risks.
In short, don't just focus on losing weight, but lose belly fat. Your cells are not sensitive to insulin, which will promote the body to store excess fat in your abdomen.
? There are three ways to determine whether you are obese or overweight. Each method has its own advantages and disadvantages.
? Body mass index (BMI)
For adults, the range of overweight and obesity is determined by a number called "Body Mass Index". This index is used to determine whether your weight is consistent with your height. To calculate your body mass index, divide your weight (kg) by the square of your height (m).
For example, if your weight is 80kg and your height is 1.5m, your body mass index can be calculated as follows: 80÷( 15× 1.5)=355. According to the body mass index, you are considered obese.
? National Institute of Diabetes, Digestion and Kidney Diseases.
Use the following references to define the body mass index:
A BMl below 18.5 is considered underweight.
18.5 and 24.9 are considered healthy.
Is a body mass index between 25 and 29.9 considered overweight? Body mass index greater than or equal to 30 is considered as obesity B.
A body mass index greater than or equal to 40 is considered obese.
? Comments on body mass index
According to a new study, if your weight is normal according to BM, it doesn't just mean that you are not obese. The position of fat in your body is more important than your overall weight. Normal weight alone is not enough. We need to re-examine the whole concept of obesity.
? According to Dr. Steven Blair, an obesity expert at the University of Southern California, "Compared with obese but active and healthy people, people with normal weight who are sedentary and unhealthy have a higher mortality rate."
Robert? Robert Ross is an exercise physiologist at Queen's University in Kingston, Ontario, Canada. He said, "A doctor should carry a tape measure with him besides a stethoscope around his neck."
? Adam, Director of Nutrition Department of British Olympic Association? Dr Adam Carey said, "The problem with focusing on BM is that it makes you focus on your weight, not your body fat." Calculating body mass index will underestimate the body fat content of muscular people, such as bodybuilders or high-level athletes, because their weight is mainly determined by muscle groups. Because the body mass index focuses on excess weight rather than the distribution of fat in the body, experts suggest that waist circumference or waist-hip ratio can be used as an additional method to determine whether people's risk of overweight or obesity-related diseases will increase.
Measure waist circumference
Measuring waist circumference is a simple way to determine how much abdominal fat is wrapped around your intestines and other abdominal organs. The bigger the waistline, the more fat you have in your stomach. This is true even if your weight is within the normal range.
? Wrap the tape measure around your bare abdomen, just above the bone. Make sure that the tape measure is flush with your waist, neither too loose nor too tight. Relax, exhale and measure your waistline.
? According to the data of the World Health Organization, if the waist circumference of men exceeds 90cm and that of women exceeds 80m, they are all obese.
Men tend to be apple-shaped, and fat is likely to accumulate in the abdomen rather than the buttocks. In contrast, women are mostly pear-shaped, with large and full hips and narrow hips.
Waist-hip ratio (WHR)
This is the third method you can use to determine the fat distribution.
Use a tape measure to measure your waist circumference at the thinnest part of the waist, and then measure your hip circumference at the widest part of the hip. Divide the waist circumference by the hip circumference. This is your waist-hip ratio. Waist-hip ratio can also be used to measure abdominal obesity.
Researchers say that if obesity is defined by waist-to-hip ratio instead of body mass index, the number of people at risk of heart attack will be three times that estimated by doctors at present.
How to calculate your waist-hip ratio
The waist-hip ratio is calculated by dividing the waist circumference (narrowest part) by the hip circumference (widest part).
? From a mathematical point of view, waist-hip ratio = waist circumference and hip circumference. For example, if you are a man with a waist circumference of 34 inches and a hip circumference of 39 inches, your waist-hip ratio is about 0.87(34 divided by 39).

? Health risks of male and female animals
Less than 0.9 less than 0.8? Low risk
0.9 - 0.99 ? The risk is 0.8-0.89
? 1.0+ 0.9+ high risk
It is said that both men with waist-hip ratio less than 1.0 and women with waist-arm ratio less than 0.8 are pear shape. This person's fat is stored in thighs and arms (subcutaneous fat).
? It is said that men with waist-hip ratio greater than 1.0 and women with waist-arm ratio greater than 0.9 are both apple-shaped bodies. This shows that their fat is mainly stored in the abdomen (visceral fat), and they are at higher risk of weight-related diseases.
If you want to reduce your waist-hip ratio, it is very important to reduce abdominal fat on the one hand and maintain muscle mass by strengthening exercise on the other. People with more muscles tend to have a larger hip circumference, so the waist-hip ratio is smaller.
A study in Sweden followed up 1400 women for 12 years. The results show that this method of detecting obesity can predict heart disease, stroke and death better than body mass index.
? Now that you know everything about obesity and overweight, let's continue to find out why some people can't lose weight no matter how hard they try.
