Heavy bloating after any meal. (fit and active, small waisted)

Hey,

I get really extreme bloating but no gas so to speak. Can't figure out what is causing it and i've isolated many foods to try and find the cause but any food seems to do it!

It is not painful but it can be very uncomfortable and persist for atleast two days!

Any ideas? Any advice would be greatly appreciated!
