As a fat dude, It is not healthy to be fat, and it is not a choice either.  It is more like an addiction to food.  that being said, saying you should be proud of being fat is ridiculous, you should strive to be healthy in stead of different.  Respecting someones views on religon are not at all the same as saying "Because I am comfertable being fat I am healthy"  It is not healthy to be fat under any circumstance.
