I did a gluten-free diet and it helped improving my digestion, but sometimes I felt quite... unsatisfied and hungry even after eating a lot. I have researched the topic and found out that one should be careful with gluten-free diet, if he does not know how to replace the nutrients such as iron that you can find in bread and other gluten products. (You can lose hair when not having enough iron). Currently I eat gluten, but less than I used to and I feel good. It is also a good point to replace (at least partially) white bread with the dark one I believe.
