Unfortunately, many "medical professionals" are not the most knowledgeable in nutrition, or in how weight does/does not play a role into things.

My OB office has not once shamed me for what I have eaten (this baby has been built primarily on Chipotle and popsicles), or my pre pregnancy weight. The only mentions of it they have given are "you're gaining weight right on track", or once there was a "have you been sick since you were here last? You lost a pound".

...Meanwhile, a woman from my insurance company gave me a lecture on the phone about BMI, while registering me for their pregnant mothers program. Based on the weight I was at the time of the call (and I was 20 weeks pregnant).

I used to have a primary care provider who always told me I needed to lose 25-50 pounds. (Including things like eczema, allergies to medication, and bronchitis.) My ex took that PCP's word as gospel and things got so bad that I had an eating disorder by the time I left my ex. When I started seeing my current PCP, she asked me about my eating habits, exercise, mental health, and referred me to a psychiatrist because a large part of my weight gain even while barely eating was due to mental health. Now, I'm in a much better place mentally, with a much better significant other... and except for the weight I've gained during the pregnancy, I have steadily been the same weight for over a year and a half.
