From a reader:

It should also be totally legit if you truly do want to lose 10lbs.  There’s no shame in setting personal goals.  Whether it’s wanting to look superhot in a bikini or have a brilliant and handsome suitor or buy a fancy Chanel handbag—if you’re motivated to get to the end result, I don’t think it’s fair for anyone to derail that by suggesting it’s superficial, egotistical or a bad example.

If it’s what you want to do, then do it and don’t feel guilty or apologetic for it.

I couldn’t have said it better myself.
