I need a Dr. Seuss for body-image

The world was given a gift with Dr. Seuss sharing the brilliance of:

Dr. Seuss wrote these words and changed how many people approach their real courage. They are able to grasp life in an embrace of freedom. 

However, it's killing me that the sentence ends there. I want Dr. Seuss to enlighten all the ways I sense myself and my world. 

Because of the secret-code-of-femininity into which I was born because of the pairing of my chromosomes, I'm pretty sure I'm not supposed to actually wonder about this out loud. Here's the thing, though, I've been wondering about it silently, internally for months now and am just stirring with curiosity about other's thoughts.

I can't keep it in any longer or I'll burst!

The thought comes in the inquisitive form: what would it be like if each of us could actually be 114% content looking however we look without slaving over constant "adjustments" or "improvements"? Specifically, what would life be like if each of us could simply be the weight our bodies want to be at any given time?

This would be a life without worrying about calories  or exercise as a means of 'transformation' or the number printed on your clothes tag or BMI's. I'm not advocating for obesity to take over the world in some binge-eating free-for-all, but, rather, for a culture in which size truly doesn't matter.

Sadly, I don't think this is possible any time soon. I can't imagine how we would function, how we would compare each other. I'm sure some of you may be thinking "You're too self-conscious. I'm totally fine being the size I am and don't feel like I need to change it." Okay, great, I'm really happy for you. My question, however, runs deeper--would you feel the same way if you were, say, four clothing sizes larger? My guess is no. And the root of my question is, why not?
