Not with regular walking, no, but last year I lost 8 lbs with:

- strength training
- interval training

I then had a leg injury (unrelated to exercise), so I had to stop. I cannot wait to go back now that I have been cleared for all exercise by a physical medicine dr.

but I do believe that walking helps me not gain weight on Zyprexa.

Also, when I did lose those 8 lbs, people commented as if I lost 20 lbs, because it was in the right place - my tummy. So I hope that by going back to strength training and interval training I will have more success.
