If you're going to accuse someone of putting their child at risk, yes, unless you have some information to back it up, it's bad. It's body shaming, but trendy because it's slamming skinny women instead of fat women. 'You're unhealthy in my eyes, so you should not be seen.'
It really isn't necessarily a skinny/fat thing. People are sensitive about every health claim around pregnancy.
Smoking, drinking, and drugs are the obvious ones, and people will condemn a mother as worse than Hitler if they ever see them doing that. But things like coffee, caffeine, certain cheeses, meats, and fish, etc etc etc are all enough to get complete strangers to give pregnant women lectures on the street.
So for me, it falls more into that category. The idea that focusing so much on staying super skinny while pregnant isn't necessarily healthy for the baby.
We obviously can't prove anything about her specific case based on a photo, but we can make general statements about what she appears to be promoting. If you are going to broadcast a message to a quarter of a million people, you can't be surprised if someone critiques that message.
