多数烟民在戒烟后一年内,其平均体重都会增加4至5 kg,其主要原因是由于戒烟后饮食量增大,导致体重增加。???另一方面,有科学家调查发现,一些烟民在戒烟后卡路里摄取量减少,但是体重仍然有所增加。对此,瑞士科研教授Gerhard Rogler表示,这可能是由于戒烟导致人体的肠内菌群发生了变化,进而影响体重变化。该教授的科研论文已于8月29日在美国科学杂志《公共科学图书馆—综合》(PLOS ONE)上发表。Gerhard Rogler教授指出,肥胖者肠道内存在着两种常见的细菌群,分别是变形菌门和拟杆菌门,这两类细菌极易分解肠 Most smokers increase their average body weight by 4 to 5 kg within one year of quitting smoking. The main reason for this is the increase in diet after quitting smoking, resulting in weight gain. On the other hand, a survey by scientists found that some smokers reduced their calorie intake after quitting their cigarettes, but the weight still increased. In this regard, Gerhard Rogler, a professor of scientific research in Switzerland, said this may be due to smoking cessation led to changes in the body’s intestinal flora, thereby affecting weight changes. The professor’s research paper was published on August 29 in the American science journal PLOS ONE. Professor Gerhard Rogler pointed out that there are two common bacterial groups in the intestine of obese people, namely, the proteobacteria and the bacteroides. These two types of bacteria can easily break down the intestines
