The British Imperial College of Technology recently issued a news bulletin saying that a new study by the school shows that obesity has different cardiovascular effects at different ages, and young people ’s blood vessels have enough adaptability to compensate for the effects of obesity. However, after middle age, this ability to adapt will gradually disappear. With the accumulation of fat, the arteries will gradually harden, which increases the risk of cardiovascular disease.
The blood flow rate in the human body will vary due to changes in blood vessel elasticity. The blood flow rate in a hardened blood vessel will be faster than the blood flow rate in a blood vessel with good elasticity, so by measuring the blood flow rate, the degree of blood vessel hardening can be calculated. In this study by the Imperial College of Technology Medical Research Council Clinical Science Center, the researchers measured the aortic blood flow rate of 200 volunteers with a magnetic resonance scanner. After comparing the data, they found that young people have too much fat , Does not cause arteriosclerosis, but when the age is over 50 years old, the effect of excessive fat on the elasticity of blood vessels begins to appear, and the degree of arteriosclerosis is significantly improved, and this effect does not vary according to gender. Based on this, the researchers believe that the body fat ratio is more closely related to arteriosclerosis than the body mass index (BMI). Body fat ratio can be measured by micro-current, under normal circumstances, the average value of male body fat ratio is 21%, female is 31%.
The leader of the study, Dr. Declan Oregen of the Imperial College of Technology, pointed out that the new research shows that the effect of fat on the body will change with age, and is related to the length of body obesity after adulthood. Therefore, for obese people, the length of obesity time and when to start losing weight will affect the final effect of weight loss.
