But now Jamil is criticizing the famous family for contributing to toxic diet culture.
On Tuesday, Kim Kardashian uploaded a sponsored Instagram post that promoted "appetite suppressant lollipops" to her 111 million followers — and the photo did *not* sit well with Jamil.
The post featured Kardashian enjoying her own Flat Tummy Co. lollipop.
"You guys... @flattummyco just dropped a new product," Kardashian captioned the selfie. "They're Appetite Suppressant Lollipops and they're literally unreal."
She added the hashtag #suckit.
Immediately, fans slammed Kardashian for promoting unhealthy dieting tactics.
"Eating is good for you, stop convincing people to literally starve themselves of food to get a flat tummy," one follower wrote.
Upon facing backlash, Kardashian quickly removed the controversial photo — but not before Jamil was able to capture a screenshot.
She took to Twitter to sound off about Kardashian's post.
"No. Fuck off. No," Jamil began her scathing post. "You terrible and toxic influence on young girls. I admire their mother’s branding capabilities, she is an exploitative but innovative genius, however this family makes me feel actual despair over what women are reduced to."
