I don't mind calling myself yogi because i like yoga and I practice ahimsa and am vegan.  I'm under no delusions that the Yoga I practice with weights in a heated room and that has lots of cardio mixed in is not traditional yoga.  That's OK.  As for the fat girl on the left in the photo.  She embraces nothing of the yoga lifestyle.  Just look at her.  And yes that's probably not a very yogi thing for me to say.
