BBC investigation finds AI fitness adverts breach UK rules

The adverts, used to sell fitness app subscriptions, promised users they could lose 40lb in 28 days or look 20 years younger, often without clearly saying the instructors were fake.
The Advertising Standards Authority said it had received about 300 AI advertising complaints in the past year and issued advice notices to advertisers flagged by the BBC over likely unsubstantiated claims.
Experts warned the ads could fuel false hope, body-image harm and injury risks, while Meta and TikTok declined to comment after the BBC found hidden, unclear or missing AI labels.

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.
