I am not an expert on the movement, but here is an excerpt from the first Google result I got explaining it:
Body positivity refers to the assertion that all people deserve to have a positive body image, regardless of how society and popular culture view ideal shape, size, and appearance.
Proponents say it helps combat discrimination faced by overweight people, while opponents say it promotes an unhealthy lifestyle. What do you guys think about it?
