I added a couple to the post above. The link with "women" in the title also includes data on men under the data tab. The gist - poor women are more likely to be gluttons than non-poor women, no big difference among men.

You've added a couple of links on obesity. Nothing on "gluttony" or the generosity or lack therof of the US welfare program.

Five minutes' Googling will make it abundantly clear that "they're fat because they have a moral failing" is a seriously unhelpful point of view.

(For anyone interested - the phrase "obesity-poverty paradox" is a good place to start.)
