Have you guys heard of prebiotic fiber? So a few years back I was at a talk and they actually showed that a lot of what we consider genetic based weight gain actually had to do with bacterial flora in the gut and you could transfer it among mice making fat mice thin and vice versa but transferring fecal pellets. So for a while people thought that probiotics were a great option but the problem is they don't colonize so you have to keep taking them every day pretty much forever for them to work. All of the latest studies suggest that by eating prebiotic fiber....this is stuff you can't digest but bacteria can you can actually change your flora instead of just supplementing it everyday. In most cases this is suggested to be done by introducing a lot of fruits and veg and whole grains instead or processed foods but there are supplements as well. Just wondering if anyone had ever tried anything like this?
