This model is not on the cover of health magazine. She's not being shown for her health status.
I'm in the camp of you can't tell anything about somebody's health by looking at them. I also think it's dangerous that we (as a country) automatically say fat=unhealthy and thin=healthy. It's dangerous for all of us. I had a friend who was talking to me about some health issues, I asked if she had been tested for type 2 because it sounded like classic symptoms.
Her response "I can't have type two diabetes, that's from being too fat. Only fat people get that. Everybody knows that." Surprisingly and sadly, she's not the only person I've heard say that. She ended up being diagnosed with her numbers and A1C through the roof and complications already starting. She figured that as long as you stay at the proper weight that you can eat however you want.
If we're going to make health a marker for magazines or celebrity so that we don't "glamorize" something unhealthy then all cover models should be vetted by a dietician, no smoking or excessive drinking allowed, no drug use or risky sex behaviors.
We glamorize plenty of people who have unhealthy habits. How is being on just the wrong side of the bmi so much worse?
