14% of people who are thin outside and fat inside are high risk of diabetes

It looks thin, and the index of obesity and thinness commonly used in physical examination also reaches the standard, but you may not be really thin.Experts said that the standard to measure whether a person is fat or thin is the BMI index. Among the people with normal BMI, 14% of them have a serious accumulation of visceral fat, which belongs to central obesity.
BMI is sometimes unreliable
BMI is widely used by the medical community as a standard to measure whether a person is fat or thin. In fact, it is not so perfect.BMI index is calculated by dividing a person's weight (kg) by the square of his height (m).The body weight is normal when the BMI is between 18.5 and 24.99, lighter when it is lower than 18, and heavier when it is higher than 25.On the Internet, there are many BMI index calculators, which are particularly convenient to calculate.
But medical experts believe that BMI is not correct, because it does not consider the nature of a person's weight.Take a football player as an example. Because of his strong muscles, his BMI may be included in the category of obesity, but in fact his body fat is not high.On the other hand, reaching the index does not necessarily mean passing the figure test.
Experts suggest that 14% of the people with normal BMI in China still show a serious accumulation of visceral fat, with more men than women. "Thin outside and fat inside" is also called apple shape
If a person's BMI is normal, but visceral fat is heavily accumulated, then he may be an apple shaped person, also known as central obesity or abdominal obesity, which is also known as "thin outside and fat inside".Although the weight and height of some people seem to "match", there are a lot of belly fat.Scientists have found that many people, especially men who are not exercising, have excessive visceral fat content despite normal body mass index (BMI), which is absolutely harmful to human health.
Some people look fat on the surface, but "inside" is not fat, which is "fat outside and thin inside" body type, such as sumo wrestlers.Japanese researchers found that although sumo wrestlers may have a BMI as high as 56 (generally speaking, more than 25 are obese), their body fat content is very low.The expert explained: "The cholesterol content and triglyceride content in sumo wrestlers are not high, and their fat is stored under the skin, not in the internal organs."
Apple is prone to diabetes
According to experts, in China, the normal fasting blood glucose is 5.6 units, and the postprandial blood glucose is 7.8 units.In case of diabetes, the normal fasting blood glucose is more than or equal to 7 units, and the postprandial blood glucose is more than or equal to 11 units.If it is between the two, it is the patient with abnormal glucose tolerance, which accounts for 15% of the whole population.Half of them will develop diabetes.The apple shaped patients will have an increased cardiovascular morbidity and mortality risk, which is a high-risk group for diabetes.
If people with an "apple shaped" figure control diet and strengthen exercise, then the waist fat will be the first "digestion".The intake of high fat and high calorie foods can be properly controlled, for example, it is better to eat less or not eat fried food.According to Modern Express
Test
Two methods, see if you are "fat inside"
How do you know if you are thin outside and fat inside?First of all, if your BMI is normal, don't be happy. It's safest to measure your waistline.
Measure the waist circumference. If the male waist circumference is greater than or equal to 90cm, the female waist circumference is greater than or equal to 85cm.
The waist circumference measurement method is also particular. The feet are 30-40 cm apart. Use a tape measure at the midpoint of the line connecting the upper edge of the right midaxillary line hip and the lower edge of the twelfth rib, and horizontally circle the abdomen.
Another algorithm is to measure the proportion. If the ratio of your waist circumference divided by your height is between 0.4 and 0.5, congratulations. Your figure is OK.If the ratio is less than 0.4, then you are too thin, and you can consider appropriate fattening.If the result of dividing waist circumference by height is greater than 0.5, then your figure will slowly turn to "apple shape".If the ratio is between 0.51 and 0.6, it indicates that there is a little more fat in your waist, and you can consider slimming. If the ratio is above 0.61, then the fat in your waist has begun to threaten your health, and it is strongly recommended that you slim down.
