Why not? My July 4th goal is going to be 215. I am at about 227 right now, and had started at 237 a little over three weeks ago. I guess I qualify for the challange now, I am single, but will be getting married in October...so this is helping me get slimmer for those wedding pictures that will be floating around the family homes for years...at least in twenty years I can be embarassed about my clothes or haircut instead of how much I weighed.
