A study has found that exercise alone may have the power to alter our gut bacteria.
Ok so this initial study was conducted on mice and not humans (as usual!)
But the results found that mice who exercised had increased levels of good microbes present in their gut, in comparison to sedentary mice.
A second study was then conducted to see if the results could be replicated in humans.
This study took a group of both lean and obese people and followed their normal diets, while they underwent a scheduled cardiovascular exercise program.
The results showed an improvement in good microbes for all subjects (although the lean participants responded much more positively to exercises than the obese participants).
I love studies that reinforce the importance of exercise for other reasons than just weight loss!
