Waist-hip ratio is an index to predict obesity in early research. The smaller the proportion, the healthier it is. This is a better way to predict whether a person is obese and at risk of heart disease, which is three times more accurate than the commonly used method of measuring body mass index (weight divided by the square of height). A large waistline indicates that there is fat in the abdomen, which is a signal of greater danger; Moreover, a person's hip circumference is large, which shows that his lower body is muscular and beneficial to people's health.
People with plenty of meat are relatively healthy and have slender limbs, but people with beer bellies are the most dangerous. Judging from the influence on blood vessels, blood lipids and arterial occlusion, the fat accumulated in the waist has a greater impact on health than the fat in the thighs and buttocks. Waist fat will destroy the insulin system, the metabolism of waist fat is quite fast, and it will also produce different hormones, leading to diseases such as diabetes, hypertension and hyperlipidemia. In addition, waist fat can also lead to liver hypertrophy, making it unable to function normally.
The method of measuring waist-hip ratio is very simple, that is, first measure the waist circumference and hip circumference, and then divide the waist circumference figure by hip circumference figure to get the ratio. If the female is below 0.85 and the male is not greater than 0.9, it means that it is within the healthy range. Waist-to-hip ratio of white men >: 1.0, and waist-to-hip ratio of women >; 0.85, for abdominal fat accumulation.
Researchers emphasize that exercise is the best way to reduce fat, and it can also strengthen the muscles of lower limbs; Dieting can not effectively change the waist-hip ratio.
For example, paying attention to the waist-hip ratio can help you know your health status at any time and establish a warning line for yourself, which is a very effective health indicator. Once the waist-hip ratio is too large, it means an increase in health risks. Diabetes and high blood pressure will easily find you; For men, it is more likely to suffer from heart disease.
Generally speaking, fat accumulation in the waist and abdomen is much more harmful to the body than accumulation in the thighs and buttocks. Obesity in the waist and abdomen can easily lead to diabetes, hypertension, coronary heart disease, stroke, hyperlipidemia and other diseases, which is why people often say that "the belt is long and the life span is short". Therefore, the waist-hip ratio is a health indicator, but the body mass index can only be regarded as a rough measure of weight and related health risks.
