I ended up telling everyone, simply for the fact that my wife told her mother. By telling her mother, she gossips and tells everyone's business, including the part of the family I don't care for very much. So I figured if those people knew than everyone I cared about should know. So I posted it on Facebook. When I lost weight before, people thought I had the surgery. So what does it matter.
Also, people who shared that they had the surgery helped me with this decision. Honestly, you can't really fool anybody that you lost weight on your own. Everyone knows Star Jones and Al Rocker had the surgery. Should it be embarrassing that you are trying to help yourself?
