"How well could she be eating? She needs to drop a few," psychiatrist and Fox News commentator Dr. Keith Ablow said on the Fox program "Outnumbered" earlier this week.
Ablow was talking about Michelle Obama. He and some of the other commentators on "Outnumbered" were complaining about the first lady's campaign to make school lunches healthier.
So what responsibility do TV doctors like Ablow have to their audience? Brian Stelter asked Dr. Gail Saltz, a psychiatrist, author and television commentator.
"When you carry the label of M.D.," she said, "you're putting forth the idea that you are going to act with integrity; that you are going to go by, frankly, American psychiatric guidelines, which is not to diagnose someone that you have ever met," etcetera.
"To be criticizing people kind of willy-nilly is - I don't think meets the Hippocratic oath. And it undermines the way the public sees mental health professionals, which is what concerns me the most."
