Well for some women it will always be impossible to fit into the "western ideal standard" of beauty. Not every girl is tall and blonde and leggy and pretty. But using that to justify obesity is bullshit. Weight is manageable. Height, body shape, skin colour etc isn't.  Body positivity is great when it's aimed at short girls, or really really tall girls, or girls who feel lesser because of their skin colour, and women who have had mastectomies or amputations or birthmarks/scars.  It's not always possible to be 'standard' or 'ideal', but it is ALWAYS possible to be slim. The aim is to love your body the way it is, be it black, white, short, tall, etc, not to poison it with sugar and crap and demand people love you.
