What are the Obesity Help membership cards used for?  Do I need to print it out to be able to do something special after surgery or to get a discount somewhere?

I think they are used at restaurants so you can eat off the kids menu.  

No, they're not good for anything.

The restaurant card another poster referred to isn't good for anything, either. They're a card anyone, WLS patient or not, can print off at home. Most restaurants that are willing to honor such a card will do the same if you just ASK. And eating off the children's menu is generally a bad idea---it's mostly high-carb, fried, unhealthy food.

Agree, but I do find it helpful to ask to order off the senior or lunch menu for dinner. I still take half or more home, but it isn't as expensive.
