Old school story books. I have some old books from when I was a kid (Serendipity books, late 70s, early 80s. I'm old, shut up), and I let my kid pick one to read for story time. We read every night and I got sick of Dr Seuss, so I got out my old books. One was called Catundra. It's about a fat cat that eats all day, then gets made fun of by the other animals, so it eats more because it's sad. Then a mouse comes along and talks her into losing weight. Makes her run and diet and exercise. Eventually she is a thin, healthy cat and is very happy and the other animals are nice to her.  What I loved about reading this to him, is that there was never a single suggestion that the other animals were bad for picking on her. The story put the onus on the fat cat to fit in to society and not the other way around.  I read my kid this story often, and we talk about why it's so important to exercise and eat right. Ah the good old days, when fat shaming was seen as a valuable public service.
