Change our bodies/change their minds: which is easier?

Change our bodies or change their minds
Lindsay at babble has this thought posted: They want us to change our bodies because they think it’s easier than changing their minds.
My thoughts on this (because of course I have an opinion, I have an opinion on everything, ya know?) are that the "they" that want us to change our bodies are all the fat-phobes who have bought into the conventional (and unproved) wisdom that says fat is always unhealthy, no matter if it's 20 lbs or 400 lbs. Those fat-phobes aren't just the common man out there, they're also the researchers that begin a study looking for reasons to vilify fat and willingly ignore everything that doesn't back up that theory. They're also the doctors that ignore research showing that being fat isn't any worse for a person's health than being thin (all factors being equal).
Why don't they want to change their minds? Could it be that then they would have to admit that they've been wrong all along? That they weren't smart enough to see through the lies they've been fed? That they started out with an erroneous assumption and ignored the results that showed they were wrong and they just can't admit that they would do something like that? That it's never been about health? That it's always been about aesthetics and selling a product we don't need, that we never needed? That it's been about greed? The more they can make us unhappy with our bodies, the more money they make off us, selling us diet plans, the perfect hair color, the tanning salons so we can have that perfect tan, the designer clothes, the wrinkle cream, the plastic surgery, the gym memberships to tone that body, all so we can meet that unattainable ideal (which keeps getting smaller and smaller). Never be satisfied with who you are or how you look, because if you ever do decide to love yourself as you are, they will cease to have a reason for existence, and you will be royally pissed about all the time, effort, emotion, and money you wasted trying to be something that you aren't and can never be, at least not permanently.
How easy is it to change our bodies to meet their ideal? Well, from my personal experience, it's more time and effort than I want to expend. I don't want to have to obsess about every bite of food I can't eat for the rest of my life. I don't want to have to live with starvation for the rest of my life. I don't want to have to spend half of my waking hours exercising like a hamster on speed trying to get thin while I'm starving myself. I have a life to live, a husband to love, books to read, movies to see, grandchildren to play with, crafts and sewing to do, shopping to do, housework and meals and laundry to do, friends to enjoy. If I'm exercising half my waking hours and starving myself, I'm not living, I'm existing. Sorry, I would rather live happy and fat, than miserable, starving, and thin. I think I'll live longer if I'm happy than I would if I was miserable, no matter what my weight happens to be. If the world of fat-phobes can't accept that, too bad, sucks to be you.
