I had IBS always since going low carb. I did find a number of foods I don't do well with: eggs, tuna, almonds, avocado. Cut out lots and it would get better, but always return.

Inexplicably since doing DDF the IBS-D is mostly gone. I'm wondering if perhaps my bowels didn't like all the fat I was eating when I was low carb. The only 2 things that have changed significantly is I am eating less (quantity), and I am cutting down on fat. Still eating the same foods, more or less.
