Well..realize everyone has an opinion. My suggestion would be to invite her to a support group, have her come with you to a doctor's appointment and have her ask him questions..even better ..have her go to a seminar on it. She may never change her mind, but it just may give her some needed perspective. I am going out on a limb and guess she never had a weight problem? She may have..but if not, remember she doesn't have an idea where you are coming from. My husband was just diagnosed with hyperthyroidism and could eat me under the table and never gain an ounce. We had often talked about it, and he admitted he didn't understand where I was coming from. But I involved him in the process, allowed him to ask tough questions to the providers, and once he learned about the process, sat in a support group, and saw the problems that come with obesity that he had never experience..he began to empathize with me...and in turn became one of my biggest supporters. Maybe that is something she would be willing to do for you as your best friend because she loves and supports you already!
