For some specialists, weight changes promote development of obesity. For regulation of the mass is an extremely complex mechanism. In general, our body can maintain a stable weight, with maximum variations of one to two kilos. But sometimes the system can deregulate and obesity appear.
For Prof. Abdul Dulloo, of the University of Zurich, the machine packs because of fluctuations on the scale. Thus, dieting and regain the pounds quickly often leads to a higher weight than that of departure: the body reacts by building up reserves, because he has just experienced a period of “famine”. This useful mechanism there is still a century, playing against us now … Especially when the spiral is the yo-yo, which leads every time a little later in the overweight.
Obesity do you get?
We often speak of an epidemic of obesity. This has scientists thinking: what if the disease had an infectious origin? Because we know many viruses that cause animal weight gain importance. At the 12th European Congress on Obesity (ECO 2003), a particular DNA viruses, the Ad 36 has been implicated. Injected into chickens, mice or monkeys, it causes an accumulation of fat up to 40% extra! But this virus has been found in obese subjects. In some studies, one third of overweight people were antibodies against the infectious agent that is to say they had been in contact with this virus at least once in their life. It seems that accelerates the formation of fat cells. For cons, the modes of contamination are still mysterious. While it is clear that no one can accuse of being a virus responsible for the epidemic of obesity, it opens an interesting avenue of research, which should certainly help to better understand the mechanisms of overweight.
