Worrying about gray hair when your weight's soaring out of control is like mowing your lawn while your house is on fire.
Control's a funny thing. It comes and goes. Some days I had it, some days I didn't. It felt like every time I did something healthy, I had this in satiable need to counterbalance it by doing something unhealthy.
My ability to tolerate shame, to compartmentalize it, to swallow it, increased right along with my belt size. it came with the territory of being heavy. Obese people have a lifetime of experience with shame.
The people who can most successfully lose weight and maintain a healthy life style are foodies. When it comes to healthy eating, people who know how to cook and make ingredients taste good have a distinct advantage over those who can't.
