Lena Dunham, who’s championed body positivity in Hollywood for years took to Instagram on Thursday to respond to online speculation about her recent weight loss. “I feel I’ve made it pretty clear over the years that I don’t give even the tiniest of shits what anyone else feels about my body. I’ve gone on red carpets in couture as a size 14. I’ve done sex scenes days after surgery, mottled with scars. I’ve accepted that my body is an ever changing organism, not a fixed entity — what goes up must come down and vice versa. I smile just as wide no matter my current size because I’m proud of what this body has seen and done and represented.” Dunham added that her battle with endometriosis led her to start exercise, so she can control the disease and anxiety.
