Again, needlessly harsh. She is psychologist with expertise in body image and was likely asked by the reporter for an opinion. Idk why you think she's trying to cash in on anything. It's incredibly cynical.
No, needfully harsh. "body image" is an invented term and "expertise" just means she got some papers published in journals controlled, most likely, by her friends. "Getting quoted in journals" would appear on her application for tenure, if she doesn't have it already.
Also, reporters don't just happen to call up random people and ask for an opinion. You call them and offer it. Get on HARO<haro@helpareporter.com> if you want to be quoted, too.
and neither is she a doctor or biological scientist. Rather, she's trying to get in on a lucrative field which she has no expertise in.
