Several researchers have found out that weight gain post quitting smoking is not really a consequence of an increased sense of appetite as is popularly assumed, but because of a change in the composition of intestinal flora after quitting. According to current trends, about 80 percent of the people who quit smoking tend to weigh 7 kilos more on an average. What is even more surprising is that their calorie levels remain the same or may, in fact, fall compared to the level before they quit smoking. So, what is it that is really causing the weight gain? Let’s find out

Changed Composition of Bacterial Diversity in Intestine

Researchers who worked with Gerhard Rogler of Zurich University Hospital attributed the cause of excessive weight gain post quitting smoking to a change in the diversity of bacteria present in the intestine. The researchers pointed out that the bacterial strains that linger in the intestinal flora of an obese person also influence him/her to give up smoking.

How the Study Derived the Conclusion: Comparison of Stool Samples

The team of researchers examined the genetic material of intestinal bacteria that were found in faeces. Alongside, they studied four stool samples per person over a period of 9 weeks. The participants included five smokers, five non-smokers and ten people who had quit smoking a week after the beginning of the study.

The results from analysis reported that even though the bacterial diversity in faeces of smokers, as well as non-smokers, changes little over time, that of those who gave up smoking made the biggest shift in the composition of microbial inhabitants. The test subjects who had quit smoking gained an average of 2.2 kilos even though their eating, as well as drinking, habits did not change.

Researchers further reported that the composition of diverse bacteria in the intestinal flora that changes after quitting smoking, probably provides the body with more energy, making non-smokers gain weight.

Further studies are being done to come to a concrete conclusion.
