The practice of consciously considering gluten is different than passively knowing facts about gluten consumption and Celiac disease.

I'm a 40-something gal, the same age Mom was when she gained 100 pounds. I've got a little extra meat, but it landed in the right places. I work out three times a week, have the energy to walk 60 blocks a day just for fun and can easily touch my toes, nose or most of my other body parts if I so choose.
