How rude!

I had a close friend ask the same question;  I just stated that while I can lose the weight, it just returns, as she well knew.  The WLS is a tool to help keep that from happening, plus this is to get your health back.

This is the result of an actual medical diagnosis:  Metabolic Syndrome.  Look it up on Google.

If she choses not to understand that reasoning, it's her problem, not yours.  Who knows, maybe your success will motivate her!

Good luck!
