There is something to be said about weight and body size in relation to health. However there is no reason that you should let physical numbers determine your value as a human being.
Women (and men too!) are under pressure every day to look and be shaped a certain way. What that shape is, depends on a lot of things including peers, career, and the media. According to your father’s career he should be rather rotund from eating a lot of donuts but if you ask GQ he should be lean and wearing jeans that cost a couple hundred bucks. However neither of those expectations will ever define or fit your father.
I never want you to fall under the illusion that the only thing valuable about you is your size because it couldn’t be further from the truth. As you get older you will feel it–that pressure to fit some mental image of the way you should look that often times is unrealistic. I just want you to remember that value comes from relationships with friends and family, a faith in what you believe, leaving a mark on this world that will last forever, and living your life with your heart. Obesity isn’t healthy and it can lead to an early death, but plenty of young women have succumb to the illness and tragedy of going too far the other way. Every minute that you spend looking in a mirror criticizing your growing and changing body is one that you are missing out on a world of opportunity away from your reflection.
Already as your mom there is no value that can be placed on your head. You are irreplaceable to me and to God. You need to be irreplaceable to yourself as well. I want you to be healthy and I understand that neither you or I will always love our appearances–I also want you to know that there is much more to your life and to your worth than what you wake up and see in a mirror.
