Changes in Intestinal Bacteria Leads to Weight Gain among Smoke Quitters

Changes in Intestinal Bacteria Leads to Weight Gain among Smoke QuittersIt has been unveiled that people gain weight when they quit smoking. Previous studies have concluded that on an average when people quit smoking they gain between four to five kilograms in the first year of quitting smoking.

Recently, a study has been carried by a group of researchers from Zurich University Hospital. As per the research, it has been unveiled that quitters are gaining despite the fact that they have not increased their calorie consumption after quitting.

The study, which has been publsihed in the scientific journal PLoS One, has been supported by the Swiss National Science Foundation. Study researchers were of the view that there are instances where quitters have even reduced their calorie intake, but then also they have been gaining weight.

One of the possible reasons for the same can be change in the composition of the intestinal flora of smokers. Study researchers carried out an experiment in which they studied the genetic profile of intestinal bacteria in faecal samples.

In total, samples of 20 volunteers were studied in the course of nine weeks. There were 5 non-smokers, 5 smokers and 10 people who had quit smoking. A great shift in the bacterial biodiversity was witnessed in Proteobacteria and Bacteroidetes in quitters.
