Misleading AI fitness adverts breach UK rules and prompt ASA advice
4 articles · Updated · BBC.com · May 7
The regulator said about 300 AI advertising complaints were received in the past year, and issued advice notices after BBC-flagged social media ads promoted implausible results and unclear AI disclosure.
The adverts used fake instructors and before-and-after imagery to sell fitness app subscriptions, with claims including losing 40lb in 28 days or looking 20 years younger.
Experts and trainers warned the content can fuel false hope, body-image pressure and injury risks, while Meta and TikTok declined to say whether users could opt out of AI-generated posts.

ASA’s AI Monitoring Scans Tens of Millions of Ads to Combat Deceptive AI-Generated Fitness Advertising
Overview
A BBC investigation in early 2026 revealed widespread AI-generated fitness ads making impossible claims and using fake instructors, leading to over 300 complaints to the UK's Advertising Standards Authority (ASA). These deceptive ads harm body image, especially among young people, and pose physical health risks by ignoring individual needs. Despite existing advertising rules, platforms like Meta and TikTok inconsistently label AI content, adding to consumer confusion and societal harm. In response, the ASA deployed an AI-powered monitoring system in 2025 that identified hundreds of violations and improved compliance in paid ads. However, policing non-paid influencer content remains challenging. The upcoming EU AI Act encourages transparency, while advertisers must adopt robust processes to ensure truthful, responsible AI advertising.
