"we should all be happy with our bodies the way they are, and so on."

Utter tripe. If you are overweight, out of shape and are at risk of being obese, with its own host of related problems, you don't celebrate that. You change your habits and get into shape in whatever way works. If you are obese or in the vicinity thereof, repeating this shallow and meaningless mantra is guaranteed to fail. It speaks volume of the equally empty culture of platitudes we're so ensconced in, no doubt reinforced by these self-helpers intent on jumping the bandwagon. If you are 80 pounds overweight and promoting "happiness" with that body, you are celebrating death. Think about it.

"And to be honest, I’d feel a lot more comfortable with this question if the sexes were reversed and it was a wife complaining about a husband."

Why are you more comfortable offering advice and criticism towards a male instead of a female? Grow a pair, Eddie.

Losing weight and getting into shape leads to real confidence.
