Exactly. Fat just makes yoga impossible.  I stayed in an ashram in India for a month(did a teacher/trainer course) a few years ago and there was an obeast staying to do the teacher training course. She couldn't do the majority of poses and whined constantly about not being able to get sugary food or fast food. You're in an ashram on the side of a fucking mountain, christ. This ashram was very strict on what you could eat and when so she ended up loosing weight very rapidly but dropped out after 2 weeks because it was "like a concentration camp". Honestly, next time I'm in India again I'm going back as I just felt that good while there but if a fat can't stuff itself to death it's apparently hell.
