The body positivity movement has its roots in the fat acceptance movement of the 1960s and 1970s. However, it wasn't until the 1990s that the movement gained momentum, with the establishment of online communities and social media platforms. Body positivity advocates argue that societal beauty standards are unrealistic and unattainable, leading to body dissatisfaction and negative body image. The movement seeks to challenge these standards, promoting acceptance and self-love instead.
