This post was inspired by Beauty Tips for Ministers: At the Weight Watchers Meeting
I've been working on this issue as well-- trying to be healthy enough to do the things I want to be physically able to do. Here are the two things I have come up with (after reading and watching way too much about the issue of weight in America).
1. Shaming people who are not thin and who don't look wonderful in an ab-revealing shirt just encourages said people to hide out in their houses and be inactive. If I feel like I have to lose 50 pounds before I am fit to be seen in public, then I'm not going to be out doing the types of things that will help get and keep me fit.
2. People fixate on the weight loss rather than the fitness (maybe because it is easier to measure) but our bodies change weight and shape all the time given stress levels, hormones, and other factors that we might not even understand yet. I would rather be fit and look overweight than try to force my body into a shape all the photos of my great-grandmothers say is just not in my DNA.
3. We don't do a good job of teaching injury management in our fitness programs. If you are going to be active, you are going to get hurt and having a plan for how to stay active while you recover from normal sports injuries will help keep you active (and should help you recover faster). Learning how to successfully recover from sports injury should be just as important as learning the sport itself.
