I used to run a really strict diet with fiber being on the low side... The performance at the gym was great, I was able to build muscle while shedding some fat and increase strength a bit too. However, I didn't like eating it, and my GI tract was hating me.

Now, I have a diet that is a little less strict, tastes good, and is super high in fiber/probiotics. I feel much better day to day and my gym performance is still pretty good. I think in the long run my second version of the diet is better because I can stick to it because I actually like it!
