Irish researchers from the University College of Cork revealed that exercise can increase the percentage of good bacteria in a person’s gut, which might help in keeping obesity at bay. Obesity chances increase due to decline in gut bacteria and also lead to weaker immune system. Athletes were found to have lower levels of inflammatory markers and better metabolic profile than the men in the comparison group. The presence of wide range of gut bacteria was higher. The number of different bacteria types was also higher. They particularly had much high proportions of Akkermansiaceae, a species of bacteria that are associated with lower rates of obesity.
