Doc tells me to beware of the inevitable weight gain I will experience when quitting smoking. I rarely need to see a doctor, but I do have a primary care physician whom I check in with once a year just to make sure I"m good. Recently my primary care moved locations, making it a 2-hour round trip to see him, so I switched doctors. A few days ago I went to my new doctor and decided to ask him for advice on quitting smoking. (I know, I know, judge all you want, I have no excuses) We talked about nicotine patches, but then he started asking me questions about my weight. For the record I have a BMI of 18.6. I weigh myself every morning just to make sure I'm maintaining and I am very careful about what I eat. I am petite and only need around 1400 calories each day, so every calorie counts, would rather kill myself than be fat, etc. So I really like this doctor, but not what he had to say next. First he asks me, "How do you feel about your body now?". I said I felt great, had no physical complaints, love being active, sick of knowing that I'm hastening my own death by smoking, etc. Then he starts talking about how nicotine is an appetite suppressant and that even though it is extremely important that I quit smoking, I should be prepared for the inevitable weight gain. He says, "You could stand to gain a few pounds anyway, you are underweight.". I said, "No, if I lost a few pounds I would be underweight, but I maintain my weight very strictly so that won't be a problem." He continues on that line of reasoning anyway. He says he just wanted to warn me because he didn't want me to become discouraged and go back to smoking just because I might gain a little weight. I just said, "Why would I gain weight if I don't change my eating habits? I mean, I understand that it may be more of a challenge, but weight gain will not be inevitable because I won't eat more than I need even if not smoking makes that more difficult, at least at first." He says, "Don't be overconfident and sabotage yourself.". Sigh. I get where he is coming from, I really do, but honestly I overcame alcoholism, I kind of have an idea of what I'm in for. But I'm willing to do it because I'm not willing to continue being a fucking idiot with my health. It's just discouraging when even doctors don't know what they're talking about when it comes to weight gain.
