3. Treating your body like someone you love will change how you feel about it.
I am whole-heartedly anti-diet. I am also whole-heartedly pro-healthy eating. Imagine if you had a child and instead of nourishing your child, you put her on diet after diet or gave her tons of junk food, made her over-exercise or didn't let her exercise at all -- and verbally abused her through all of this. If we treated our children the way we sometimes treat our bodies, it would be abuse. Treat your body like you love it. Feed it like you love it. Move it like you love it. Talk to it like you love it. Give it rest and treat it kindly.
(P.S. For people who haven't been treating their bodies lovingly for a while, this may result in some physical changes. Funny how that works, huh?)
