I'm on Kaiser Permanente which has HMO down to a science

Over a year ago, I tried their "weight loss program" which basically consisted of going to a weight loss counselor who would give you advice about your diet and exercise and would also weigh you. They also offered medication, meredia and xenical if you wanted. I tried the meredia but after 1 month and an elevated blood pressure, they took me off of it. They also had classes you had to take as well as seminars. The classes were on diet and exercise.
Anyway, when I started the program, they gave me the option of going the surgical or non surgical route, I took the non surgical route. Although I was on that path, the classes and seminars had people doing both things so I was able to talk with a lot of women who were trying to get approved for the surgery. Of course they had more things to do then me like psychological evaluations and such, but the basics were the same, they had to go to the classes and go to the counselor just the same and it was a process that took between 18-24 months for them. So I would say it depends on your insurance and maybe your doctor?
