my wife's weight issues

In the last year, my wife decided to use a trainer and get on a good diet. It has been like a religion to her. To her credit, she has lost over 50 pounds, but if anything she has overdone a good thing. Now I barely see her eat anything. When my kids and I eat meals, she putters around the kitchen and says she's not hungry or that she'll get something later. She is so obsessed with her body image that I'm worried that she could have an eating disorder or be anorexic.
I don't want our teenaged daughter to go down the path of extremism but I fear she is also picking up on her mother's obsession with her body.

i agree she may be setting a bad example to your daughter. i would sit down with your daughter and explain how people can tend to overcompensate on a "good thing" and that just becaue mom does it, doesn't mean it's the right thing to do.

My sister had a similar situation and her husband was very diplomatic in discussing good eating habits and self-discipline with their kids. You have to be both open and gentle.
