Need ideas for friend activities

I'm 55 and am trying to lose weight (a great gift from the meds)! What kind of activities can I do with my women friends that don't involve a lot of food? I am sick of the movies. I live in a large city so most things should be available. Thanks so much...my head gets so full from medicine I can't think!

Here are some things I do. I try to keep up with the listings in a few different papers because I like random, strange (and free) events.

Visit museums/attractions/gardens
Walk/Hike/Visit parks and beaches
Attend lectures at libraries, museums, university, etc
Attend musical performances
Go to plays/readings - especially on pay-what-you-can nights.
Volunteer gardening

Hiking and other outdoor recreational activities, like kayaking and whatnot! Also, workshops or classes for shared interests would be fun to take with friends I'd guess. Karaoke? Maybe make your own book club with them or something?

go to the art galleries

I walk with friends. We have plenty of time to chat then and afterwards we visit a little longer with a bottle of water each. That's all. But it's something we look forward to ...

Bowling
Minigolf
Volunteer as a group for something (walking animals for a shelter, playing cards/visiting at a nursing home)
Play cards
Concerts(lots are free. check out your local newspaper should have listings)
learn a craft together(knitting, crocheting, painting etc.)
