Jameela Jamil has given her two cents on Serena Williams’ endorsement of the GLP-1 weight loss drug. On August 21, 2025, the tennis legend, in an Interview with PEOPLE, revealed that she had recently used the GLP-1 weight loss drug and lost about 31 pounds.

Williams, 43, emphasized that she did her research on the product to discover its benefits and possible side effects:

“I did a lot of research on it," she told People about her decision. "I was like, 'Is this a shortcut? What are the benefits? What are not the benefits?'

She added:

"I really wanted to dive into it before I just did it. They were super supportive, and it was easy to get the medication. I lost over 31 pounds using my GLP-1 and was excited about that weight loss.”

Jameela Jamil, who never shies away from making commentary on social issues, expressed on her Instagram Story that she was “uncomfortable” with the star athlete encouraging the use of the GLP-1 weight loss product:

"Serena Williams is selling GLP-1s. The thing I feel most uncomfortable about here is that celebrities have access to doctors that most others don't have access to. These 'miracle' weight loss drugs come at a price."

"The side effects can include paralysis of the gastric system, pancreatitis and cancer,” Jameela Jamil warns about the use of weight loss drugs

While Jameela Jamil didn’t specifically mention GLP-1, she warned about the use of weight loss drugs, stating that their use could be disadvantageous:

"These 'miracle' weight loss drugs come at a price. 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, blindness, and they can really wreak havoc on your metabolism."

The British actress, model and activist stated that most people who use weight loss drugs end up gaining back the weight. The 39-year-old added that media advertisements didn’t warn users of the adverse effects.

The multi-hyphenate expressed that she disliked celebrities encouraging the use of such high-risk drugs when they have the means and resources to deal with the impact, as opposed to the ordinary user.
