Good leg fat, the dangerous belly fat
The position of the flab can decide on the health. According to a recent study older women’s diseases a reduced risk for cardiovascular, if your fat deposits lie on the legs. The fat sits on the belly, rises ill the probability to.
For the study, the researchers examined data from women who were of normal weight and the change had. How much the fat contained in your body, overall, had little effect on the heart and circulation. Important is the location of the fat depots, was alone, the researchers report Qibin Qi from the Albert Einstein College of Medicine in New York in the “European Heart Journal”.
A total of nearly 2,700 women participated in the study, were observed for 18 years. To the beginning of the study none of the participants nor a proven cardiovascular disease. Within the observation period, but developed 202 of the women to have a heart attack or other disorders of the coronary arteries, 105, had a stroke.
Worst combination: a Lot of fat on the belly, hardly any fat on the legs
When the researchers analysed the cases of illness in connection with the fat distribution of the women showed:
- The quarter of women with the most abdominal fat had to develop at almost twice the risk of serious cardiovascular disease than other participants.
- In the case of the legs, the tendency was the opposite: women’s, deposited there a lot of fat, had fat an almost 40 percent lower risk for cardiovascular disease than women with very little Leg.
- The highest cardiovascular-risk women, where a large part of the Fat was deposited in the belly and only a little in the legs. The risk was more than three times as high as in the case of women, to the contrary, the distribution of fat.
“People should, in addition to the weight control also on the distribution of body fat, even if you have a healthy body weight and a normal BMI,” said Qi according to a communication from the European society of cardiology, the journal publishes. The company points out that the fat distribution is due in part genetically, but also through diet and exercise can be influenced.
X-ray technique for fat determination
For the analysis, the researcher is not just the leg or the abdominal circumference. Instead, they determined the fat content, with a special x-ray technique (DXA). However, women had legs with a high waist circumference also tends to be more fat on the belly, and those with high hip circumference and more fat on the top. In addition, the researchers included in their calculations, factors such as age and ethnicity of the women, which can affect the weight.
The current investigation is according to the researchers, the first such study with normal-weight women beyond the menopause, the results are limited only to this group of people. In addition, the scientists with the data were able to show that fat distribution and heart disease are linked but not sure show that the distribution of fat is also a disease is the cause of cardiovascular. However, previous studies have shown that a reduction in abdominal Fat to better heart can lead to values.
Legs: “the ideal place to store Fat”
There is evidence that the legs were “store is an ideal place for Fat,” write the researchers. Why the fat is there a protective effect could not yet been clarified. It is clear, however, that the fat may intervene on the belly in important metabolic processes and the risk of diseases increase.
Fat deposits in the legs could save unnecessary calories without harming the body, write to Matthias Blüher and Ulrich run out of the University of Leipzig, in a comment on the study. Although is also conceivable that it will produce healthy substances, still it was but speculation. Even if a certain distribution of fat seems to be positive, it should be a lot of research work is necessary to understand the mechanism and the connection to the corresponding diseases.
Many experts now see the waist circumference in addition to BMI as a significant factor to determine the risk of disease of a Person. The scope should not exceed, according to the German society for nutrition in women is 80 and for men 94 cm.
