Hand's-down the biggest objection I hear from clients about accepting their body is that by accepting it they are either giving up or implying they prefer their body this way.  That's not what acceptance is about at all.  Saying you accept something is not the same thing as saying you prefer it that way.

Consider this, I may not prefer that it's been 90 degrees outside while I'm in my last month of pregnancy, but I accept this to be the case, and I've coped with it just fine.

Body acceptance is about acknowledging and honoring your body's size and shape, even if it's not what you (or society) would prefer.  When you accept your body you are infinitely more likely to treat it well.
