Jameela Jamil has called out Serena Williams for promoting weight-loss medication

Jameela Jamil has called out Serena Williams for promoting weight-loss medication.

The 43-year-old tennis champion revealed last week that she shed 31lbs using the GLP-1 treatment - which includes the likes of Ozempic and Mounjaro and a plays a key role in regulating blood sugar, appetite, and digestion.

However, Jameela - who has been outspoken on issues including weight culture and body image - has slammed Serena and said she finds it "uncomfortable" that she is promoting a costly drug that could potentially have many side effects and find users re-gaining the weight should they no longer afford it.

The 39-year-old actress penned on her Instagram Story: "Serena Williams is selling GLP-1s.

"The thing I feel most uncomfortable about here is that celebrities have access to doctors most others don't have access to. These 'miracle' weight loss drugs come at a price."

She continued: "The side effects can include paralysis of the gastric system, pancreatitis, cancer, hair loss, osteoporosis, severe malnutrition, muscle mass loss, depression (there have been reports of suicide), thyroid issues, and blindness. If for some reason you suddenly have to come off, many people gain the weight back and then some, fast. And it's much harder to then lose."
