Dr Amir Khan has a warning about a weight loss drug, telling people: “Do not buy this product”. It comes as weight loss medications have surged in popularity. Millions are now using GLP-1 receptor agonist drugs like Wegovy and Mounjaro
However, alongside widespread use is the risk of fake AI-generated ads, which is the main reason behind Dr Amir Khan’s recent online warning. Taking to Instagram, the NHS GP and ITV resident doctor told his followers that he had seen a fake AI-generated video of himself advertising a particular weight loss medication called ‘Osanix’
In the caption of the video, he said: “Team, I’m so sorry but a company is using a deepfake AI video of mine and making it look like I’m advertising their nonsense product, Osanix – DO NOT BUY IT. I don’t know what it in, it could be riddled with dude effects it probably won’t work – don’t waste your hard earned cash on it

“I’m sorry if you’ve already bought it thinking I was supporting it, I’m not, please spread the message or reshare this video. Thank you for your time I know this is super annoying.”
In the video itself, Dr Amir Khanclaimed that he has had “so many people” message him asking whether they should use it for weight loss. He said he even had messages from family members about it after they saw what they believed was him advertising it
“It’s not me, it’s fake AI. They’re using some old video of mine and rehashing it into a fake”, he said. “They’ve used other celebrities as well, like Peter Kay and Jeremy Clarkson
“It’s not real, do not buy it. I don’t know what’s in it, it could be riddled with side effects. I wouldn’t buy it. I wouldn’t spend a penny on it, I wouldn’t put it in my body.” He also said that if a company “has to use fake AI nonsense and use someone who people trust to sell their stuff, that company and product cannot be trusted.”
He stressed: “Do not buy this product under any circumstances. I hate wasting my time on this, but unfortunately, it’s going to become more and more common, and I will try and call out each fake product as it comes along.”
Many people shared their thoughts in the comment section. One viewer said: “Thank you for sharing this Dr Amir.” Someone else said: “I was surprised when I saw the video… didn’t think for a min it was you.”
Claire Hattrick, who is known online as The Executive Menopause Coach, said: “I hear you Amir! I’ve got 2 companies using my content at the moment and refusing point blank to acknowledge any of my emails!”
What are the risks of fake AI-generated ads?
Artificial intelligence-generated fake ads pose dangers, including financial fraud, identity and voice theft downloads from malicious links, and significant harm to the reputations of genuine brands and public figures they support
Fake AI-generated ads that push weight loss drugs are often unapproved supplements and fake GLP-1 medications. Scammers often use artificial intelligence to imitate voices, impersonate healthcare professionals, and produce deepfakes of celebrities or real doctors to deceive people into purchasing dangerous products

How to be safe if you’re considering weight loss drugs:
To safely use weight loss medications, it’s important to get them from a qualified healthcare provider and have a thorough clinical evaluation instead of purchasing them from unregulated online sites. Well-known drugs such as semaglutide (Wegovy) and tirzepatide (Mounjaro) are prescription-only options that need careful medical oversight to handle side effects and confirm they are appropriate for your health
Weight loss medications aren’t safe for everyone. It’s best to steer clear of them or consult a specialist if you have:
A personal or family history of medullary thyroid carcinoma
Multiple Endocrine Neoplasia syndrome type 2
If you are currently pregnant or breastfeeding
A past of pancreatitis or severe gastroparesis
