Exercise Boosts Healthy Gut Bacteria
Exercise not only to get fit but also to boost the healthy bacteria inside your gut. Researchers studied 32 sedentary adults without diabetes, ages 20 to 45. Half of the participants were lean, while the other half were obese. For six weeks, they rode stationary bikes or used treadmills for up to 60 minutes three times a week. Then they stopped exercising for six weeks. The researchers took fecal samples at intervals to determine the number of gut bacteria that aid in the production of short-chain fatty acids. These fatty acids help improve insulin sensitivity, reduce inflammation, and curb appetite. Exercise boosted the number of such gut bacteria by an average of 137 percent for lean participants and 31 percent for those who were obese. How’s that for an incentive to lose weight? But you must keep up your workout regimen: The gut benefits disappeared once participants returned to the couch.
