Baloney!! I knew an opera singer, fairly tanky. She could not afford to exercise too much (she suggested) because body bulk gave the best accoustics. I also have heard the skinniest soprano sing the most beautiful aria ever. I think it's baloney.
I did see one opera in which the well-padded heroine rolled onto her back like a pillbug and could not get up. for a moment. due to her bulk. A scene which will forever be etched in my brain.

Dear bboop,
I'll just point out that the article merely said that vigorous singing promotes a chemical that increases appetite. That does not inevitably lead to heft.
