I'm sure the artist had the best of intentions and believes the above ideas -- most people do these days. I'd like to put the artist at the table of a family who is trying to raise a young person with a predisposition for an eating disorder. Or even a family without that, just one that believes in a balanced approach to eating and does not engage in size-shaming.
UPDATE: The hospital has pulled down the image and apologized. The image came - thank you to anonymous for finding this - from a years-old DVD cover by an organization promoting vegetarianism. See comments for link.
