Lee, arguing with these women is an exercise in futility. As this discussion has amply shown, many overfat women live in denial, both about their responsibility for why they are overfat and how it affects their attractiveness to men. And it is this denial that prevents them from making changes. We can reason with them until we are blue in the face, but they wont see until they are ready to see.
As I mentioned earlier, thats one huge difference Ive noticed between the typical overweight man and typical overweight woman. The man has no delusions about his excess fat, and that clarity of thought is what allows him to make a change. In your case, for example, if I asked you how you got fat, you'd say what you said earlier - that you sat around and ate too much and didn't move enough. Ask a typical woman (typical, not all women) how she became fat, and you'll get a very different response. If you are blind as to your role in bringing about a particular situation, you won't see how you have the power to change the situation.
Ethyl, you understand the math now? Or are you going to continue to berate me about how Ive got it wrong?
And if you've comprehended what I've written in this thread, you'd know that a man has no need for a BMI calculator. His eyes and brain are wired to do the relevant processing. I'd explain it, but if you didn't get it the first time, you won't get it the second time either.
I didnt expect to change any womans mind here. The whole overweight/body image thing is such an intensely emotionally-laden subject for most women that many create their own little alternate reality (e.g., ask a fat woman what she ate that day) and there is no piercing that bubble, and attempts at doing so are typically met with aggressive defensiveness. It will only come down when the woman is ready to have it come down.
What I do get out of these types of discussions is a better understanding of how to avoid a woman who, while currently not fat, is likely to get fat down the road (after marriage, kids, etc.). It is not a random luck of the draw (except in the small % of cases where hormones get screwed up by meds for some illness, etc.). The signs are usually there, if one knows what to look for.
