Problem: fat women suffer higher health, financial, and social consequences than men. Obese women suffer more discrimination based on their size than men do, and therefore have fewer resources with which to address health problems.
Solution: Lose some weight, fatties.
That was my interpretation of the article, anyway. Of course, we could try and overcome fat hatred and biases against fat people - maybe even address the institutional problems that contribute to higher obesity amongst those living in poverty - but that would break with the proud tradition of making women responsible for the problems that discrimination brings them.
