When Kardashian shared her latest Instagram post promoting Flat Tummy Co's meal-replacement shakes, which claim to help with weight loss goals, Jamil commented with a scathing response telling Kardashian to "be smarter than this."
Jamil's comment begins by calling out Kardashian's access to possible additional help, such as a personal trainer and nutritionist, and suggests that the reality TV star should consider how her posts could "hurt other girls."
"It's incredibly awful that this industry bullied you until you became this fixated on your appearance," the actress wrote. "That's the media's fault. But now please don't put that back into the world, and hurt other girls, the way you have been hurt. You're a smart woman. Be smarter than this."
Jamil also goes on to list what she says are potential side effects of Flat Tummy Co products, including "cramping, stomach pains, diarrhea, and dehydration" from its Flat Tummy Tea.While no side effects for the meal-replacement shakes promoted by Kardashian appear on Flat Tummy Co's website, some of the possible side effects Jamil lists on Instagram are mentioned by the brand as potential side effects of drinking Flat Tummy Tea .
"If you're too irresponsible to: a) own up to the fact that you have a personal trainer, nutritionist, probable chef, and a surgeon to achieve your aesthetic, rather than this laxative product...And b) tell them the side effects of this NON-FDA approved product, that most doctors are saying aren't healthy. Side effects such as: Possible Flat Tummy Tea side effects are cramping, stomach pains, diarrhea and dehydration... Then I guess I have to," Jamil wrote.
According to the company's website, "there shouldn't be any crazy side effects" because the "tea cleanse is 100% natural and doesn't have any nasties in it." However, the company says that its "Cleanse (evening) tea does work to help detoxify your body and may help you go to the bathroom," adding that consumers shouldn't be concerned as "it's really gentle."
The company also mentions experiencing possible dehydration. "You might find if you don't drink enough water that you'll get a little dehydrated so make sure you keep the water up," its website says.
A representative for Jameela Jamil declined to comment further. Representatives for Khloe Kardashian and Flat Tummy Co did not immediately respond to INSIDER's request for comment.
