"Also, the ability to get to 100 pounds overweight without only mild loss of professional and social status (instead of the severe loss women face) is a male privilege of sorts."

Women don't face a severe loss of professional status if they put on weight, unless their employer enjoys being cleaned out in court. And as for a loss of social status - try being an obese man for a while and see how that works out for you. They get ripped on just as bad as obese women.
