Saying nothing, not doing much is abit difficult

[OakLeaf]

If your doctor is telling you to lose weight when your BF is 20% (I would've actually guessed lower from your photos) I'd get a new doctor. Unless she's actually telling you to lose muscle, which would be medically supported, but in that case you're as noncompliant as anyone. http://hyper.ahajournals.org/content/30/6/1511.full

But to stay on topic, your health is your doctor's business. Using health as a pretext to body shame peers is not anyone's business. Do we all do it inside our own heads? Probably, just like the saying goes we're all a little bit racist. It's what we say out loud and how hard we work not to express those inner prejudices that counts.
